Eyepiece | 6.4mm Plossl | ||
Observing notes: |
This was my first chance to view Mars. After all the hype I was quite looking forward to this session. My last view of Mars over a year ago was very disappointing. Not this time. I immediately observed Mars with the 6.4mm plossl. At first Mars seemed very bright and featureless but as my eyes became dark adapted detail started to emerge. The first thing I saw was the polar cap, a bright white patch arcing over the top of the planet. I then picked out the grey shading on the planet stretching from east to west and from the center of the band it went south forming a large, flat 'Y' shape. I spent quite some time viewing this detail looking for anything extra but nothing else was seen.
Ricoh RDC 6000 digital camera hand held to
a 6.4mm eyepiece.
I then tried to find Uranus but failed miserably. I kept star hopping to the same point
and even on highest power all I had was a point of light. I thought if I had viewed
Uranus I would have seen a small disk at least! Oh well another time....
Whilst I was out I took the opportunity to check out some old favourites. M13 was looking good in the 6.4mm
resolving many stars and chains of stars outside the main halo. M57 was easily visible and showed up well. The
double cluster looked good in the 32mm as did M32.

My new 10mm eyepiece is giving good details
of mars. The low level means that any higher magnification is almost useless. The southern polar cap is prominent as is the dark triangle of
syrtis major.
M27 showed a hazy smudge, although it did seem to have a bit of an
hourglass shape.

Viewing conditions: | 5, Mediocre |
Telescope | 6" Newtonian f/6.83 Indian make |
Eyepiece | 25mm , 12mm Astro, 6mm Super Astro and 1.5x, 2x Barlows |
Observing notes: |
First observation of Mars at these times of
the spectacular opposition. After a slight manoeuvring of the scope,
Mars slowly drifted into the field of view. The detection was done using
a 25mm Plossl eyepiece.
Immediately after capturing, power was raised to 85x using a 12mm
ASTRO eyepiece and some light and dark features of Mars became evident. At
first, the Southern Polar Ice-cap was not visible, but a slightly more careful observation and perhaps a little dark adaptation by that time
made the ice cap visible.
The ice-cap was spectacular, bright white covering a small area in the
form a perfect arc shifted to the left (East) from perfect south in the
scope. That is probably because of the tilt in the axis of Mars.
Apart from the ice cap, a pattern of dark areas was also visible.
Running from the eastern side of the planet to about half the distance across
was a broad "gully", first bifurcating at the eastern end (where it
starts) and then bifurcating into two arms, one going to the south pole
and almost touching the ice cap and the other one forming an arc towards
the west. I could be wrong to some extent in discerning the exact shape
of these areas, because of several factors, including poor
transparency, poor seeing and eyepieces not being perfectly clean.
To my surprise, Mars resisted 170x and stood magnificently in the
field of view. In fact at 170x, colours of Mars were very clear. The areas
other than the dark ones, were light rust (slightly reddish). This
colour contrast was not discernable at lower powers. In fact, at lower
powers, the whole planet other than the dark areas was yellow in colour.

Observing notes: |
Took the chance to use my colour filters on mars and found that the yellow helped bring out detail very well although I am still confounded by the atmosphere as it is so low in the sky. When mars disappeared behind trees I looked at the moon and found that it was taking x320 magnification quite well so for a laugh I put in my old Tasco 4mm ramsden eyepiece and my barlow( x600!!!). Unbelievable! Te view was perfect and so close I thought I could rake trough the regolith with my fingers! The detail in the crater walls was breathtaking. I cant wait to see how it performs in better conditions! |

I saw M13 and M92 resolve into stars for the first time. M27 was clear
and apple core shaped, I saw the m29 and 39 clusters in Cygnus and the
double cluster in perseus which literally took my breath away. M71 was
just visible and M31 and 32 were showing more detail than I have ever
seen before.

At the moment Mars is visible between my neighbours two trees for about 30mins or so after midnight. I have had a
couple of successful sessions and have seen the southern polar cap and
some vague dark markings although it looks like it is dust storm season
to me!
After mars was out of view I tied to find the north American nebular
and once again failed miserably! moving on I found M57(cearest and
brightest ever) and M13 (also brighter). I did find M92 in my 10 times 50
binoculars but cloud covered it before I could aim my telescope.
Moving back to lyra I could not find M56 so I moved on to m29 the open
cluster which was not terribly impressive. By then the clouds were
rolling in and the moon was rising so I finished with some always
wonderful highpower lunar observing.
Comment: All in all a mixed evening with regards to success but I am
improving my observing skills! |

Viewing conditions: | average |
Telescope | TAL 2 M 6" f8 reflector |
Eyepiece | 40mm plossl, 25mm plossl, 7.5mm plossl |
Observing notes: |
I have been using this telescope for a
month or so and have been amazed at the images of Jupiter and Saturn. I
could view these perfectly at 320 times magnification.
However from my back garden deep sky objects fainter than M42 are
almost impossible. Finally though after a hell of a lot of trying I star
hopped my way to M57, the ring nebular. It is incredibly faint and it took
me along time to make sure it was actually there and not just my eyes!
It looked like a faint circular smudge with the insides just fainter
than the rest.
Encouraged by this I looked for M13 which all the books describe as a
very bright and obvious globular cluster. Not from Hull it's not!
It is perhaps a smidgen brighter than M57 but shows no detail and
certainly no individual stars as promised!

This was the first time i used this scope
or any scope to look at mars. I tried 3 different eye pieces to get the
best view. With the 25mm and 12.5mm used with the 2x barlow I could
make out the polar cap and very faint dark marks on the planet. I could
not get the 10mm or 7.5mm to focus clearly. I plan to send more time on
Mars as the months go by. You are right it is difficult find good
information when choosing a scope.

Viewing conditions: | Clear and cool (50 degrees) |
Telescope | 6" Bushnell Voyager Dobsonian Reflector |
Eyepiece | 26mm Super Plossl and 6mm Plossl |
Observing notes: |
SATURN--disappointing, I know I should have
left the scope out to cool down. It was 50 degrees and Cassini's
Division was near impossible to see. Rhea and Titan were visible and many
stars were near, one of Titan's exact brightness. M35 was very near and
bright, seen in finderscope even! It's hard to detect moons as easy
with Saturn being in such a rich star field. Rather annoying actually!
Jupiter--Io and Europa formed another tight pair. Ganymede and
Callisto were visible in the finderscope. From the time when I first went
out, through when I went in, I could easily see the change in position of
Io and Europa. They switched places.
I tracked Jupiter until 8:00 a.m. when I bumped the scope off-course.
The sun was clearly up over the horizon, and I could still see Jupiter
in the finderscope even! Naked eye visibility remained for a
surprisingly long while (when knowing right where to look). The best part of
all is when I looked at Jupiter for one of the final times around 7:30
and I could still see Io and Europa! I didn't look for Ganymede or
Callisto for I was too excited at the fact I could see these two moons AFTER
the sun was above the horizon! For 5th Magnitude objects, this is
amazing!
Jupiter never looked any less appealing or fuzzy due to the sunlight.
Actually, it looked nicer with more defined markings as did Saturn a
few weeks ago. They both take on a greyish look but are still quite
nicer (in some aspects) nonetheless.

Observing Location: | St. Louis Missouri suburbs |
Object Observed: | Jupiter and Saturn |
Viewing conditions: | Normal/clear |
Telescope | 6" Bushnell Voyager Dobsonian Reflector |
Eyepiece | 26 and 12.4mm Super Plossls, 6mm Plossl, 2x barlow |
Observing notes: |
Jupiter's moons--at 5:02 a.m. EDT: Europa
and Io were to be apart by only 2". This would not work for me because
at that time (4:02 a.m here), Jupiter (Mag. -1.9, 33.9") would still be
too low. I still got up at 5:20 though. The moons had separated but
were still close, nonetheless. From when I first went out, til the end,
I could notice the difference in distance between the two moons. The
largest separation between Jupiter and Callisto I have ever seen took
place, too.
I went inside to get on the computer because Io was so close to
Jupiter, I suspected a transit to be occurring, if not soon. As it turns out,
it was in transit (shadow).
I did not know if I could see it in the 6mm (200x) but I tried anyway
and did see it. If I knew exactly where it was, and looked there, my
eyes might tell me I'm seeing it when I'm really not, so I looked for it
through the scope and THEN confirmed it to be where I noticed it by
checking the computer. It was fairly easy to see, but I knew which side
of the planet to look on.
The speck of a shadow was SO black! It looked foreign and almost as if
it was invading on the surface of red and white. The GRS did not look
like a cavity in the bands as it did the first time I saw it, but I
knew there was a red bulge there--whether it was the GRS, I do not know.
One hemisphere looked redder than the other end. There was a hint of
festoons between the NEB and the SEB. The Io shadow transit was
somewhat above (below in reality) the equator.
Saturn (Mag. 0.1, 18.8") was quite impressive tonight because of the
moons. I was thinking of how there's four or five present and this must
be a record for me! Titan was the brightest by far. Cassini was
simple as always. I looked for the Crepe Ring and I had no luck. Saturn is
just too bright to see it, I believe. Try again next time. Iapetus
(Mag. 11.1) was the hardest to see. Titan (Mag. 8.3) and Rhea (Mag. 9.7)
were easy as they usually are. Dione (Mag. 10.4) was not so hard to
find. If I would have looked harder, I could have seen Tethys and
Enceladus probably.
Comment: Shadow transit seen through the 6mm (200x). I do not remember
if the 12.4mm or the 6mm with the barlow showed it or not.

Observing Session Details : Saturn was as bright and sharp as I've ever

"moons" of the same brightness as Titan and only one was Titan. Rhea
was near too. The disk, or ball, looked just like a crystal-clear,
yellow-white-grey marble with a brownish band. Cassini's Division was
superb. This was as close as I have come yet to a textbook picture! Using
the 2x barlow and the 6mm, magnification is pushed up to 400X, that's
67x per inch of aperture. Far beyond the traditional 50 or even 60x
rule, and it was still definitely worth viewing.
M45 (Pleiades) were unimpressive. The clouds made for may varying
stars! I could see the Double Cluster with my naked eye. M42 and M43
(Orion Nebula) were not good because of the rising sun.
No Jupiter yet.

Telescope | 6" Bushnell Voyager Dobsonian Reflector |
Eyepiece | 26mm Meade Super Plossl, 12mm Meade Super Plossl, 9 and 6mm Plossls, Meade 2x barlow |
Observing notes: |
I don't know why the Pleiades really aren't
exciting in the eyepiece...??? Only naked-eye do they seem enjoyable.
Anyway, Saturn was wonderful! There were four moons this time! Twice
as many as ever before. Rhea, Titan, Tethys, and Dione.
SATURN: Mag. 0.0, 18.3"
Excellent Cassini Division with planet shadow on rings and stars all
around. After checking with computer programs, I need to make in-field
drawings and look for Iapetus next time. Titan blended in well with
everything else, not overwhelmingly bright...I don't know why. I viewed
Dione well into the blue sky! It was amazing how long it lasted despite
sunrise. I could have kept tracking it into the daylight longer but
having to do it manually was just taking too long and I ended up getting
distracted and stopping at 7 a.m. At that point, it still held a
spooky grey look at 200x. I lost it in the finderscope by then though.
Saturn's detail on the globe itself was even easier to tell in the
daylight.
Even before daylight, it would hop around a bit and then become crystal
clear, which is rather surprising because of how many moons I could
see. However, I did not let my scope cool off which would make a
difference I am sure. Also, these moons were not illusions, they were present.
At the powers of 133x and 200x, a couple of these moons needed averted
vision and came and went from view. However, with the barlow at 400x,
the moons were for sure "real" and not just illusions. This
combination of 6mm Plossl and 2x barlow made for difficult focussing but a rather
large view of the planet. It's worth at try for sure.
JUPITER: Mag. -1.9, 33.0"
Behind the trees still (I live on a hill)...only two bands seen. Three
of four moons seen too. Better observing when it gets higher.

Object Observed: | Jupiter, Saturn, moon |
Viewing conditions: | Average for a suburban location, light pollution |
Telescope | 90mm Celestron C-90 |
Eyepiece | 9mm |
Observing notes: |
This is just a reply to Jeff's comments and
my own observations with the Celestron C-90. His observations were
almost 3 years ago and he was very unsatisfied with the views he got of
Jupiter and Saturn. I got my C-90 back around 1980 and have gotten great
use out of it.
Jupiter as viewed by Jeff at 80X and 159X - no detail on Jupiter- no
clouds, no red spot, no nothing. My comments - I routinely used a 9mm
ortho on Jupiter and even under poor seeing condition I could always see
at least 2 belts, under very good conditions 4 and sometimes 6 cloud
belts were visible. Never seem the great red spot though.
Saturn as viewed by Jeff at 80X and 159X - At 80X Saturn was so tiny
you can just make out the rings, but just barely, one moon visible, no
detail at all, not very bright. My comments, using the same 9mm ortho
Saturn is impressive in this small scope. Under good conditions Cassini's
division is easy and on occasion the polar hood and rarely a cloud
belt.
A side remark. I have seen 2 cloud belts on Jupiter with a 40MM
refractor working at 60X as well the Cassini division with the same scope.
Both Jupiter and Saturn are bright and clear. I will say that until you
get used to focusing the C-90 it can be hard to get a sharp focus.
Comment: I still have this scope and have it mounted on a photographic
tripod for impromptu observing. I had in mounted on a equatorial for
several years when I used it as the main scope when I taught beginning and
intermediate astronomy in Adult Education for 7 years. I say all this
to show that the little C-90 is a nice scope and had served me well. I
suspect that Jeff had very bad conditions or was a very inexperienced
observer when he got his C-90. It does take time to get used to any scope
and to become an experienced observer. I am not in any way connected
with Celestron or own any of their stock.

Viewing conditions: | Clear, no Moon |
Telescope | Orion Europa 6" reflector |
Eyepiece | 32mm Sirius Plossl, 25mm + 9mm Kelner, 6.4mm Plossl, 2x Barlow |
Observing notes: |
I've been wanting to find NGC6543 (Mag 9.0) for quite some time now and had my star charts ready. I started off
by trying to star hop from between Chi Draconis and Aldhibah but I kept losing my way! Scanning
the area with binoculars I came across a 'fuzzy' patch and through the scope this asterism
looked just like a mini cassiopea! It's between and slightly above Chi Draconis and Phi Draconis. Nice....
From here I star hopped to what I thought was the right area using the 32mm eyepiece but I could see nothing.
I increased the power by using the 2x barlow and there it was! A small (and I mean small) round smudge that
was quite bright! Using the 25mm kelner and the barlow the object remained very bright and was incredibly round.
I tried all sorts of magnifications on this object and the 12.5mm and 9mm powers gave the best views with the hint of a
fainter edge surrounding the nebula using the 9mm. Beyond that the object was 'lost in the contrast'.
Viewing at low power with the 25mm the nebula looked like a faint star with a hint of nebulosity that gave the impression
of being blue or at least a blueish tinge. I lost this impression of colour at higher powers.
Next I decided to try and split Polaris (I'd read that it was a double but didn't recall any other information). Easy to locate,
I bumped up the power to 230x magnification. I could see a faint star just of Polaris and I thought that this was the double. On
checking my charts when I was back inside I was dissapointed to find that this wasn't the double star! I don't think I
split polaris with the maximum power I have available to me... oh well, maybe another day!

Observing notes: |
Wonderful night! The only reason I went
down to the field was because of how bright the sky was. I have never
noticed the Milky Way here at home before. This was truly spectacular!
I went first for M4 in Scorpius because it was low. Interesting
globular with a line of bright stars cutting through the center. M22 and
M15 (globulars) were also seen. All of them were easy to resolve (the
stars in them) perhaps M4 was best. I compared these to M13, and the
difference is the compact brightness of M13. None were disappointing.
The Lagoon (M8) and Trifid (M20) nebulae were disappointing though.
The Lagoon could be seen well but not the Trifid. Both were seen
together as a naked eye fuzz. (No color of course through eyepiece or naked
eye.)
I scanned the Milky Way and through the finder found M11. This
instantly became my favorite Messier with tight stars which all could be
resolved as stars easily. There was one bright one in the cluster that
stood out most though. Other open clusters were M103 and one labelled "Tr1"
in my Peterson's Field Guides of Stars and Planets. The Double Cluster
(NGC 884 and 869) was nice. M24 is a large and quite "naked eye"
cluster in the Milky Way. It was quite nice and surprisingly large. M16
was a small cluster with NGC 6611 (Nebula) very faintly detectable. M17
was a neat nebula that looked like a small comet with an additional
tail like Hale-Bopp had.
I tried for M51 but once again for some reason, it was hard to find and
all I saw was small, double fuzz hardly detectable.
Uranus looked disc-like.
M76 and M33 were misses...I failed, unfortunately, on these.
It was also too late for M6 and M7 by now which I tried for
anyway--only to find them below the trees.
M31 (Andromeda Galaxy) was somewhat interesting with a long and narrow
surface with a bright core. I was looking at it through the 6mm (200X)
when I didn't realize I wasn't using the 26mm (46X) and found a small
galaxy near it. There was a great debate with myself as to which
satellite galaxy it was and as it turns out, it was M32. I could not even
see M110.
Also, I saw three meteors--must be early Perseids.
Comment: All observing of deep sky objects on this list can be done
quite well with a low-power eyepiece such as my 25 or 26mm eyepieces.
However, globulars are best found in the low-power and then upgraded to a
higher power (9 or 6mm). When the higher power is in, almost always,
stars will be seen then within the globular cluster.

Observing notes: |
Uranus--
I tried for Uranus first because it was brighter (thinking it would
help in finding Neptune). This one was found in the binoculars and then
the scope. It was tiny and I could surprisingly see the disk but only
because I knew what to look for. It is fun seeing "stars" that aren't
on the map knowing they don't belong there and are actually planets. I
feel like Galileo did when he found Neptune but ignored it even though
it was not on star charts. It showed a bluish-green hue.
Neptune--
harder to find and NOT seen in binoculars. I was fortunate that I was
guided to it without really trying. Not really disk-like though.
Comment: 26mm (46X) is good for finding, and then switch to 9mm (133X)
for larger views. 26mm is the best though...it's all which is really
needed.

Observing notes: |
Titan was clearly visible. Rhea was seen
easier than it used to be (April 28). Sometimes it took averted vision
to see Rhea...at times I thought there were other (moons possibly) to
the right. To the unaided eye, Saturn was quite orange as was it
through the eyepieces.
The background was a beautiful blue due to the rising Sun. The
Pleiades weren't too impressive in the dawn.
With the barlow at 400x, I couldn't focus on Saturn very well but Rhea
was undoubtedly there.
Cassini Division not seen but a dark band near the equator was.
Quite exciting to see Saturn again.
Comment: Jupiter not visible yet.

Viewing conditions: | Normal/Clear |
Telescope | 6" Bushnell Voyager Dobsonian Reflector |
Eyepiece | 25mm (48X) Kellner |
Observing notes: |
I started out with my normal hop to M57 and
it was normal. When deciding what to find next, I looked in my
Peterson's guide and saw that M56 was near, so I went for it. It took careful
star hopping but I soon found it. Everytime I am in the right area, I
am looking and expect to find something smaller than it really is.
This time it was small and fuzzy, but neat none-the-less. I could not
find it in the 9 or 6mms well. Only the 25mm was productive. It is small
compared to M13.
The scope's up and down movement sticking caused other eyepieces to be
too hard to use. On smaller objects such as this, the barlow is going
to be too hard to use (plus its small field of view).
Next, I went over to M27 (Dumbell). It was now high enough--which I've
been waiting for. I knew the general area where it was going to be
(from star charts) and I thought to myself how funny it would be to find
it on accident and sure enough, I went to check out this nearby star
grouping and just randomly scanned to the right and there it was. So to
make sure I could get back to it again, I tried it and it worked. M27
was very big compared to M57. Noticeable notches near corners. Quite
impressive and big!
Earlier, when I first received my scope, I could not find M39, but
tonight I did. It had about 30 brilliant blue stars--the most amazing
stars I've ever seen! They were all the same color. This was so amazing!
It is my new favorite Messier. I never thought of open clusters as
being so amazing, but this was my first and it was wonderful. Thank you,
God for Your artwork!
Also, I gave Albireo a try . I keep reading about the blue and orange
star contrast and it was nothing spectacular, but it was a very
interesting double star because of such a color difference.

Viewing conditions: | Clear |
Telescope | 6" Bushnell Voyager Reflector Dobsonian |
Eyepiece | 25mm Kellner (48X), 9mm Plossl (133X) |
Observing notes: |
I observed my "usuals" (M57 and M13) and
showed my father M57, he liked it a lot. When I went to show him M13, I
couldn't find it because it was at our zenith and too hard to try for
because of the movement of the Dobsonian mount. I danced around Cygnus
(a new constellation for me) for a while and found M29--a small open
cluster. It was very unimpressive but now I can say that I have one more
Messier added to my list. M29 appeared to shape a "V" or a misshapen
"X" and took up just a small section of the field of view in the 25mm
(48X)...wish I would have tried the 9 or 6mm. After that, I tried for
M39, also in Cygnus, but with no such success at finding it.
(NOTE: Two weeks earlier, I observed Jupiter for the last time on May
25 and 26, but the full moon dims everything out so significantly. M57
and M13 were barely visible. Jupiter showed three bands and darkening
near the top.)
Comment: When confirming what I have seen, the National Audubon Society
Field Guide to the Night Sky is a very useful tool. I use Peterson
Field Guides: Stars and Planets' charts with stars down to the 7th
magnitude to find the object and then confirm it with Audubon's gallery of
Messier object pictures. The picture of M29 in it is a very accurate idea
of what it looks like.

Viewing conditions: | Fine |
Telescope | 6" Bushnell Voyager Reflector Dobsonian |
Eyepiece | 25mm Kellner (48X), 9mm Plossl (133X), and 6mm Plossl (200X) |
Observing notes: |
Moon was at quarter phase. Tried many
different eyepiece and moon filter comos. The best one (but not best
magnification) was with the 9mm (133X). The 6mm (200X) did provide some
amazing views! On the moon, my father and I focused on Montes Apenninus
near Mare Imbrium. At quarter phase, this range was right on the edge
and showed some peaks slightly inside the shaded region that were in the
sunlight, so they appeared as two bright stars on the surface of the
moon--perfect timing there! Near it, there was a steak on the surface
that I assumed was an angled meteor strike, but after seeing the lunar
maps, it is a valley: Vallis Alpes.
Also, I looked at Mizar A and B. This is an easy double to see both
stars. The gap between them is noticeable in all eyepieces but obviously
so much more in the 6mm. Recommended easy double for anyone.
Comment: When I read about collimation of the Newtonian, all articles
always talk about concentric cirlces...I have never seen them! When I
put the star during a star test out of focus, I do not see these
circles, but instead the 4 spokes holding the secondary mirror. Is this bad?
Why don't I see these circles?

Viewing conditions: | Thin whispy clouds |
Telescope | 6" Bushnell Voyager Reflector Dobsonian |
Eyepiece | 25mm (48X) and 9mm (133X) |
Observing notes: |
I had some time to kill, so I tried to
detect sunspots by projecting the sun through a low power eyepiece onto a
2'x 2' piece of posterboard--and it worked! There were three distinct
areas of spots and one near the right edge. Also, near the edges, I
could see the granularity that is present. (The following day I observed
one spot that was near the edge and it rotated with the sun to the left
slightly, so now it was no longer almost wrapping around the edge.
Venus was near the moon, so I gave it a shot...and sure enough, there
it was! VERY bright! Quite surprising considering the thin clouds
floating through. Couldn't ever get it in the telescope though. It is
easiest when it is near the moon as a reference. Interesting observing
session...
Comment: It is now July, and since then, I have tried 5 or 6 times
since then to find Venus in the daytime...and no luck. It is only easily
done if it is near the moon, I believe...I could be wrong though???

Viewing conditions: | Clear |
Telescope | 6" Bushnell Voyager Reflector Dobsonian |
Eyepiece | 25mm (48X) and 9mm (133X) |
Observing notes: |
Ikeya-Zhang was brighter, fuzzier and
larger through the binoculars than before, but it seems dimmer and smaller
in the eyepieces this time. However, through both eyepieces, M13 was
better. Definite stars were seen! (Almost seems to form an "X"...)
I then took a swing over to M57 (Ring Nebula), like always. It was no
different, with the center not being really seen through the 25mm
(48X), but in the 9mm (133X), it was seen. Overall, M57 seems the same size
as Jupiter.
Ahh, now for the tricky one! M51 always escapes me and I never get to
find it...this time, I did though. It was hard to see well...big but a
lot of dimness. Only in the 25mm (48X) could I see it and it was
distinct what I was looking at. (9mm was a useless view) No spiralness
was detectable but they were both very large, therefore I was impressed.
M51 cannot be seen without noticing its companion NGC 5195. They were
connected by a bridge of fuzz. Overall, with this new one, I am
pleased. They will bring nice views at a darker sky site.
Comment: Low power is the only way I can imagine finding M51 (Whirlpool
Galaxy). I have seen it one other time since then (and I am writing
this in July) and it was barely visible (not sure why). It is a tough one
for me--maybe because there are no stars to hop with that I have found.

Eyepiece | 25mm (48X) and 9mm (133X) |
Observing notes: |
I find myself disappointed because Saturn ducked behind the trees within a moment after I began looking. Titan was far away from Saturn on the left. There was noticeable darkening on upper left and right of the disk and with an overall slightly yellow tint to the planet. Jupiter was the best seeing ever--I thought I was seeing more belts than ever too but my eye may have been playing tricks on me! This was the second time I saw three belts (NEB, SEB, and the little one below the NEB). Also, I could see the hollo cavity where the GRS until recently was. Jovian moons blended in with stars somewhat, which is odd, but I could tell which ones they were for sure. Truly wonderful seeing tonight! With Comet Ikeya-Zhang, I didn't see it for the first time until well after its peak-brightness. It was below one of the "squares" in Draco. It took me forever to find it but finally did in the finderscope of all places! and when I saw it in the eyepiece it was a small cotton ball the same size as M13 with it's brightest part near the low-center area of it. Glad to finally get to say I saw it and not have missed out on this popular comet. M13 was again found in the finderscope just like Comet I-Z. It was the same size as the comet and almost identical in all ways. At 133X with the 9mm eyepiece, with averted vision, some stars could barely and briefly be seen, it is mostly a big fuzzed-out area. A successful and high quantity and quality night. THANKS, GOD FOR SUCH WONDERFUL ARTWORK! Comment: By all means, anyone reading this who finds it useful, let me know. Encouragement helps us all :) |

Wow! What can I say?! The entire time,
all I could think was: "This is nothing short of spectacular."
Compared to last night's attempt through the trees with the 9mm, this was far better of an idea of what I truly should see. The 9mm (133X) showed the SEB and NEB and Jupiter was about the size of a pencil eraser. In the 25mm (48X) Jupiter was small and crisp with both bands very prominent on the disc. (Both views, of course, showed the moons with two on each side of the planet.) When it came to Saturn, the spectacularness was ever more amazing! The view of this planet was rather wavy--as if looking across a barbeque pit. Occasionally a moon could be made out around 1-2 o'clock from Saturn. I first began to suspect it and later confirmed it by seeing it better. This must be because the eye is becoming used to the light. Titan was clearly visible much farther away and about 5 o'clock from the planet. After checking positions of the moons on the Solar System Simulator website, the moon turned out to be Rhea. On the left portion of the rings, I MAY have slightly seen the Cassini's Division. Atmospheric conditions prevented further seeing. On the top portion of Saturn (South), there were darkened areas noticeable around both left and right edges giving it a more rounded look. Mars and Venus did not yield much excitement. Venus was mostly full, but the right of it was clearly not full. Overall, at low (48X) magnification, Venus is way too bright to look at. Mars was bigger than a dot, smaller then pencil lead, and considerably red. Not much to look at here. I tried for the last view of the Orion Nebula of the year and it was impressive but short lived because as soon as I aimed to it, it was ducking below a hill. However, both M42 and M43 were seen. M42 was brilliantly whispy with stars in it and M43. Wonderful night for the new scope! |

Observing notes: |
This is my forth visit to Leyburn and also
probably my last before the winter. This was also supposed to be a test
trip to see if I could take the cool-cold temperatures of winter, which
will hit next month (needless to say that I won't be going the next
month due to my aversion to cold temperatures…unable to focus…brain and
finger freeze). Weather for the past few days prior to the trip was
excellent with clear skies. As we drove out, there were some clouds
gathering though. Well hopefully we will get clear skies from the word go when
we get there. As we had set out early, we got there just before 4pm.
During the southern autumn, the skies start getting dark at 5pm and will
be fully dark when it hits 6pm. When we got there the skies were
spectacular. There were some clouds hovering around but they were never
really a threat.
We began the night with a special treat with the planetary conjunction.
Caught Jupiter, Venus, Mars and Saturn all close to one another. Kev
tried to find Mercury in the muck before the sun had even set with his
80mm binocs mounted on a mop stick (ingenious way to mount your super
binoc) but to no success. I had a brief glimpse of Jupiter, Saturn and
Venus in Dave's 10" but as the scope was still cooling I did not get the
best views of the planets. I was still lingering on Jupiter when I
noticed how dark the sky was already. I then decided to start my mad dash to
bag all the galaxies I had on my list (much smaller this time as I
wanted quality over quantity this time).
Started out with Leo as this will be the first constellation to set
(well for the objects on my list anyway). Set out to bag two rather bright
galaxies NGC 2903 and 3607 in Leo. Turns out that I did not need to
work very hard. NGC 3607 was a rather bright elliptical close to the
M65/66 trio while 2903, at the extreme end of the lion's tail was another
easy spiral. Its amazing how easy galaxies are when you are viewing from
a dark sky site. Not a problem at all (and I event caught the M65/66
cluster in my 10x50mm binocs). Got M95 this time round (could not dodge
me anymore). Not much detail there.
Next on my list were…well more galaxies! Charged right on to Canes
Venatici and bagged all the galaxies I missed the last time round (the sky
transparency was super excellent tonight!). I had not even expected to
bag some of the galaxies mentioned later on as they are located fairly
low in the sky. Bagged NGC's 4631, 4449, 4490 and M106 (woohoo!). Of
the four, the most outstanding was 4631 with the irregular mottling seen
all across the face of the galaxy. In fact the mottling was so
prominent that I did not even need averted vision. What a treat as I did not
expect such detail from these galaxies. Had a brief glimpse of M51 as
well and it too looked much better tonight (even in my 6"…last time all I
saw were two fuzzy blobs devoid of any detail). Though I saw a hint of
the spiral arms and that bridge connecting the two!
Virgo was up next. I had failed to see some of the galaxies there the
last time I was here. Did not intend to fail this time! As such I
managed to get them all (well those on my list anyway): 4535 (near M49 which
was visible in my 10x50mm) and M89 and M90. While I was at it, I swung
my scope around to…naturally Coma Berenices and caught M98 and M99. I
have tried these two from home but failed so it was pretty refreshing to
see them so easily in my 6" under Leyburn skies. M98 was particularly
interesting appearing as a nice sliver of light. Also managed to squeeze
in M91 and M88 while I was at it. Not much detail seen in those two. It
was at this time when one of the member's (Peter) came on over with his
newly purchased Howie Glatter laser pointer and started to show off his
new toy. He pointed out this galaxy at the head of Centaurus (one that
I had not seen)…NGC 5102 I think. Pretty bright but small galaxy that
one.
Did also try to bag two rather bright galaxies in Ursa Major (the only
ones in which I deemed were high enough to find….a major portion of
Ursa Major, save its legs are all but invisible from my altitude). The two
on my list was NGC 3184 and 2841. Did not manage to see any of them.
Well I have to give them a miss…probably to low in the murk!
With all those in the bag it was now time for some fun and for more of
my faves. I will not elaborate further here as it would only seem all
too repetitive, but I will note some rather exceptional observations. Of
the objects I revisited (ditched my 6" in favour of Dave's 10" DOB…well
not for all objects but for most of them anyway): globs with very good
resolution ; Omega Centauri, M13, M5, M4, M22 and a very low 47 Tucana;
nebulae M42, Eta Carina, M8 the Lagoon and the Trifid and planetaries
M57 (nice ghostly ring in the 6". Nice nebulosity within the "smoke
hole" in the 10"), M27 (looks more like a football with the UHC in
place..even in the 6") and NGC 5189, the spiral/leafy sea dragon nebula in
Musca (nice even in my 6" with heaps of detail seen. It appeared more like
spiral galaxy with the spiral's easily visible….I later noted that I
could catch most of the details even from my mag 5-5.5 skies back in the
suburbs through the UHC in my 6"…ahhhh don't you just love technology!) . The things to note was the rusty reds seen in the
outstretched arms of the Orion Nebula (never noticed that before) and some reds
in the Trifid in the 10" (Notice how I don't have any reports on how
objects looked liked through Kev's 16" this time round. I purposefully
stayed away so as not to spoil the view in my 6"). Oh and did I mention
that we could spy NGC 5128 (Centaurus A galaxy) with the naked eye…yup
the skies were that good!!!!!
Well my next dark sky report may possible be several months from now as
its time for hibernation (well I will still be out under the stars…but
from the comfort of my apartment's balcony :)

Observing notes: |
This was my third trip to the dark sky site
over at Leyburn and I had a huge list of objects to hunt down (namely
galaxies in the Coma-Virgo). But I promised myself not to rush through
the list so I could scrutinise each and every object to tease out the
finer details. The weather was not the greatest. In fact when we got
there the skies looked pretty angry to the north. There was even a slight
drizzle which sent everyone scurrying for tarps to put over their
scopes. But as always, Leyburn never fails to surprise. The skies did clear
later at close to 8pm (starting from the south as usual. This time of
the year the skies start getting dark at 6pm). Some of the objects I had
planned for the early part of the night were now too low. Even the sky
seemed not to be of exceptional brilliance tonight. There seemed to be
some sort of haze about.
At this time of the year both the SMC and LMC together with the centre
of our galaxy (i.e the milky way) is visible. Talk about the best of
both worlds!!!! I can't remember which object I started out with but I
was quite sure it was 47 Tucana in the SMC. Not too brilliant as it was
rather low in the sky to start with. Still some resolution was visible.
Just had to have a go at it! Next up was the Tarantula in the LMC. Its
funny how the UHC filter (first time in Leyburn too!) did not visibly
improve the view (same for M42 later). Tried it also in the 10" and got
the same result. The Tarantula's extended arms were seen better minus
the UHC. I then proceeded to my fave object the Eta Carina Nebula. This
one looked brilliant and I was surprised at how much more detail was
visible when the UHC was in place in the 6"EQ. All the dark knots and
mottling were visible (and did I mention that the keyhole was
outstanding???). I later had a look through my buddy Dave's 6" Synta Refractor!
with the UHC and I was blown away. The contrast in the refractor with
the UHC had to be seen to be believe (with much more detail and
contrast then even the 10" Dob could muster). Talk about legendary refractor
-like contrast. The dark regions were pitch black and the nebular
regions looked..well distinctly nebular!
Next up was the Orion nebula M42 which was by now pretty low in the
sky. Like I mentioned before more outer nebulosity was seen without the
UHC in then with the UHC in place (strange). Also had a go at the
Christmas Tree/Flame Nebula (NGC 2024) near the horsehead. Did not look as
good then when I last saw it. Probably also due to its low altitude. I did
manage to catch it with some difficulty in the 6" though. Had to place
the bright star just out of the field in order to see the nebula and
its dark lanes. It was easier in the 10" so I made my sketch using
Dave's 10". Also note that the UHC did not improve the view of this object!
Tried to locate the horsehead with the UHC in place but to no avail. I
will have to try it again when Orion is high in the sky! Also spent
some time with some old fave's like Omega Centauri (the resolution was
just amazing even in a 6"), NGC 5128-Centaurus A galaxy dust lane clearly
visible and NGC 4945 edge on all in Centaurus.
With the perennial fave's out of the way, the next target's were mostly
faint and dim smudges.the galaxies. Remember how I for some strange
reason could not find M83 in Hydra in the 6" on my last outing?
Realised that I was star hopping in the opposite direction. The star patterns
on either side were pretty similar. Caught it this time. Nice face on
spiral with two spiral arms visible in the 6" with difficulty (saw three
in the 16" but more on that later ļ). Then it was on to Leo which was
getting a little bit too low for my liking. Caught the usual M65/66 and
their NGC companion. Much brighter than from home. Then moved on to the
M95/96/105 cluster. Caught all of them excluding M95 (again could not
find this one.for some strange reason that cannot yet be explained!).
Will have to try again for that one. One thing to note was that I
though I could make out some detail in M96 spiral arms in the 6". Then again
maybe it was just my imagination running wild yet again.
Moved on to Coma after that and had a look at NGC 4565 yet again (it
appeared like a photograph in the 16"¡Kbut again for later) and by chance
stumbled upon a much fainter NGC 4494. Thought I had 4565 but then
again it could not have been so dim so I checked the map and
whalla another new galaxy in the books!!!! Also looked at some galaxies in the Ursa
Major-Canes Venatici region. This region has several good galaxies of
optimum brightness that will show detail in a 6" under good conditions.
Unfortunately they are also located at a very low altitude from
Brisbane. This did not deter me nevertheless. I did managed to bag the
M94-Croc's eye from my mag 6 skies back home but just could not get M63-the
sunflower galaxy, only a few degrees away from this galaxy. This time I
managed to bag it. Could not see any of the mottling that O'Meara saw.
Also caught the extremely faint glow of M51 in the 6". It was a
extremely difficult catch for me as it was just a subtle brightening of
the background. Did see what I though was a central starlike nucleus
though and its smaller companion. This was really pushing the envelope as
it was in a ridiculously low altitude from where we were. Did get a
much better view of it through the 16" though.
Had planned to observe several other objects in the
Sagittarius-Scorpius region but alas dew set in. It was just 1am but everything other than
those powered ep's and scopes were drenched. That was when I called it
a night.
P/s: The highlight of the night would have to be looking at stuff
through a fellow member's (Kev's) 16" Truss Scope. We had a look at many and I mean many, many objects. Had a look at Omega Centauri. Again the
snaking chain of stars, the two dark eyes in the glob and the 3D effect
were seen. 47 Tuc was brilliant (resolved right to the core) despite its
low altitude as was NGC 3132 the Eight Burst Planetary Nebula in Vela
(again the 8 shell's of nebulosity was seen). The dust lanes in M104 and
NGC 5128 were so wide you could drive a dump truck through them (a
sliver of nebulosity was noted in the dust lane of NGC 5128). Also there
were some strange objects that we looked at that I could have sworn
should have shown more structure in a 16" like the Ghost of Jupiter in
Hydra, M64, the black eye galaxy in Coma and M83, the face on spiral in
Hydra. I could not make out the CBS eye structure in the Ghost of Jupiter
nor the dark lane in M64 which was visible the last time round in!
my 6". M83 too was not much better than in the 6" with the spiral arms
looking only a little bit more pronounced (with three arms now
visible). Was it the transparency of the skies which made the difference????
Its also amazing to note how globular's take on an identity of their own
when viewed though larger apertures. There was this glob we looked at
that resembled a starfish with its outstretched arms of stars. Can't put
an NGC number to it but it was nicknamed the starfish glob by Kev. He
also showed us a very strange looking planetary called the spiral
planetary in Musca (his nickname was the "leafy sea dragon nebula" as its
shape really resembled the leafy sea dragon seahorses found in South
Australian waters I think it was NGC 5189). Some objects really resembled
photographs (excluding the glob's which looked better than in the
overexposed photographs). The Trifid Nebula in Sagittarius was one of them
looking like a photograph minus the bright pastel color's (some !
rusty red's were visible though with the usual green's). The !
edge on spiral in Coma 4565 was also brilliant with the central bulge,
its radiating arms and the dark, dark dust lane. Wow! Also managed to
see the spiral arms in M51 connecting it to its smaller companion but
the word here is visible rather than spectacular well till next time.
Comment: Will have to pace myself better with a smaller list and to not
be distracted by 16" DOBS :) |

Date and time of Observation: | March 22-23, 2002 |
Observing Location: | Mooresville, NC.....my backyard, naked eye limit about magnitude 4 |
Object Observed: | M13, M42, Ikeya-Zhang |
Viewing conditions: | average some twinkle, but clear skies and moon went down around 1AM |
Telescope | 150 mm Orion Skyview Deluxe f/5 |
Eyepiece | 9mm, 25mm Sirius Plossl's |
Observing notes: |
This will be my first posted observation.
I got my telescope a month or two ago, and recently I have decided to
keep somewhat of a observing journal. For about a solid week the skies
were very clouded here in NC, and I got very observing in. I had been
looking forward to catching the comet Ikeya-Zhang. It was supposed to
be at its brightest after mid-March. Finally the skies cleared on the
22nd and I setup early to get a glimpse of the comet. The sun sank in
the west, followed by Venus appearing low in the west chasing the sun.
I could not see that it showed phases. After it was sufficiently dark
I started scanning the N-NW, and soon found Ikeya-Zhang, it was roughly
3.5mag, which was not so naked eye because it was so near the horizon
where light pollution is a problem. I viewed the comet first through my
9mm eyepiece(83x) I could not produce any detail out of the head or
tail. It was very uniform, quite a pretty sight, but I would have !
liked the comet to have been located closer to the zenith. The tail of
the comet was substantial spanning the entire field of even my
25mm(30x) eyepiece.
On the following night(3-23-2002) I decided that I would take a look at
M42(Orion Nebula). Winter will be gone before we know it, and so I
decided to take a long look at M42 while I had the chance. Even through
my finder scope M42 is stunning. Through my 9mm eyepiece I clearly
split the Trapizium inside the hearth of the nebula. The nebula is tinted
green. Through the 25mm eyepiece I had enough field to produce a nice
frame of stars around the nebula. Compared to pictures of the nebula, I
only see the brightest parts, while the wispy outer cloud structure
evades me. I really long for dark sky.
Later on the night of the 23rd I waited for Hercules to rise up from
the west. One high enough in the sky to get a good view of the constellation I began my search for M13. I use the
Cambridge star atlas as my
guide while I am outside. When I am at my computer I use Starry Night
software as my "virtual planetarium". M13 was one of the easiest
messiers that I have found. Once locked in on it I spent about half an hour
trying to catch some stars resolve around the fringes of the cluster.
It seemed to help to put the cluster halfway out of the FOV and use
averted vision, but still, I was unable to positively resolve any of the
blur into stars. Still the cluster was quite bright, especially toward
the core.
Overall I am very happy with my scope, and cant wait to get to a dark
site. I am looking to possibly join a local astronomy club, and my
university holds star parties on the campus observatory which are nice.
Happy Observing

Observing Location: | Backyard. Hillsdale, NJ |
Object Observed: | 3 Classical planets and open cluster M45, Moon 1/2 full |
Viewing conditions: | Clear skies, Very bright Moon, some star "twinkle" |
Telescope | 6" Orion Skyview Deluxe |
Eyepiece | Orion Plossl 9MM, 25MM and Orion 3X Barlow |
Observing notes: |
The moon was very bright and best viewed
using the 25MM and a moon filter.
This was done before sundown before the moon became to bright against
the night sky. Beautiful view.
Venus was in the Western sky, low to the horizon and also very bright,
again best viewed when using a moon or medium blue filter. It set very
quickly but will be around for the next month or so. Very pretty
against the early evening sky.
Saturn and Jupiter have been "up" for quite a while now and I never get
tired of looking at them. The 25MM and 3X Barlow combination work very
well together on these two. The 9MM and 3X Barlow was a little to
strong for the seeing conditions last night, but the 9MM alone worked out
very nicely.
What can I say about m45? It's always there just off the sholder of
Orion and always provides a spectacular view. 25MM seems about right
with my 6"
Reflector. The "sisters stand out bright and clear in the eyepiece
with very little clarity loss at the edges.
This is my first Medium size telescope, (previously I used a 90MM
Refractor of questionable quality) and every time I use it I'm amazed at the difference
a good quality 6" reflector makes.
Good viewing and Clear Skies to all.
Comment: Thanks for an excellent web site. I only just found it the
other day, but I will be a constant visitor and contributor.

Observing notes: |
Started off the evening looking for M79 a globular cluster in Lepus. The constellation was
low in the sky sitting in the sky glow from Nottingham. No chance of finding this object.
Turned the scope on Saturn which is also heading down towards the horizon. The view was not
brilliant and high power resulted in a blurred image. I could make out two moons and the Cassini
division using moderate power.
Jupiter. Now this is much higher in the sky and gave up more detail than Saturn. The moons were
all to the left of the planet as you looked through the eyepiece with two moons very close to
each other and the planet. The two main belts were strikingly clear and the southern polar
region also gave up some detail.
I then tried to find some galaxies in Leo but failed. I didn't expect to find them as Leo
was in a poor position from my observing site.
Ursa Major was sitting high in the sky and I went in search of two objects I hadn't found before,
M97 The Owl nebula (mag 11) and the galaxy M108 (mag 10). Both objects are quite close to
Beta Ursa Major. Using my star chart I was able to follow a trail of three stars between mag 8 and 9.
This leads you right to the galaxy. At first I could see nothing but as my eyes became
accustomed to the
dark the faint shape of the elongated galaxy could be made out. It was extremely faint but you
definitely got the impression of a long thin galaxy. Averted vision gave a better view giving the
galaxy a mottled appearance.
A little further south from the galaxy (and were in the same field of view in a 25mm eyepiece) there
is another group of three stars forming three sides of a box. The nebula M97 forms the fourth
corner of this box shape. The nebula was visible in the 32mm eyepiece and stood out much better using
the 32mm and the 2x barlow. This was a faint smudge and was quite large in size,
definitely larger than
the ring nebula. It seemed to have quite an irregular shape, using the skyglow filter the nebula
was a little better defined and had a more circular appearance.
That was it for tonight. Thin cloud was rolling in. I'd viewed a few old favourites and had
first light on two more objects that were the faintest I've viewed to date, mags 10 and 11.

Date and time of Observation: | 12/13th of January 2002 |
Observing Location: | Leyburn, Queensland, Australia |
Object Observed: | Various |
Viewing conditions: | Good transparency magnitude 6.5 or 7 skies |
Telescope | 6" Synta Catadioptric Newtonian (1400mm f/l), 10x50mm binocs and on occasion a 10" DOB and 16" Truss |
Eyepiece | 25mm Kellner, 20mm Plossl, 12.5mm Plossl and 9mm Kellner |
Observing notes: |
My second visit to Leyburn and boy was I in
a rush. Have not been to a dark sky site since November due to the
southern summer weather (i.e. more cloud cover and rains). I had been
planning this trip for about two months now. Anyway, the weather did not
look great from Brisbane. The forecast was for fine hot weather but fine
does not necessarily mean clear skies. As we got nearer, it still did
not look promising but we went anyway. Friday night reports filtering
through sounded positive though. We got there at about 6pm, just enough
time to set the scopes up and let it cool (or warm up..it was warmer
outdoors than in the car with the air con running). Astronomical twilight
only descended on us at about 8.30pm (when it got really dark). There
was still some clouds in the sky but the southern sky was clear...first
up...the LMC and SMC's.
The LMC and SMC was higher up in the sky early in the night than the
last time we were here. Wanted to see M32 and M33 but the skies over
there were clouded over. Would not have gotten a very good look anyway as
they were pretty low in the sky. Warmed up with 47 Tuc with the new
12.5mm Plossl. Looking great with stars resolved across its face. Spent
several minutes on this object...brilliant from a dark sky with chains of
stars radiating outwards (this effect is invisible from my mag 5
suburban skies)! Will get a chance to compare it with Omega Centauri later
tonight :). The Tarantula also looked brilliant with the 12.5mm. Heaps of
faint tendrils seen.
And now the highlight of the night! I was invited over to look through
a 16" truss owned by a member of the society. WOW was all I could
say...47 Tuc was resolved all the way to the core (you could change the
focus and resolve stars at different level's giving it a much more 3D view
than in the 10"). All the stars looked golden! Also looked at the
Tarantula...more nebulosity and knots than you could possibly imagine...much
better looking than those burned out photo's. Also caught a glimpse of
the Eight Burst Nebula in Vela (NGC 3132). It looked plain in my 6" but
I could see why it was called the Eight Burst in this monster scope.
The greenish planetary was huge with about 8 outer shells in the 16". He
put in an O III but that seemed to hurt the image (but more core
details were seen). Next was Eta Carine...superb in the 16" with the homunculus clearly
visible at high power with two shells visible...will have to
look and see if I can see that in my 6" later. Also caught Linear...nice bright nucleus and short dust tail in the 16" and M42 the
great nebula in Orion (did look great for a while before the high altitude
clouds hit)....Time to get back down to earth!
At about 12am, the clouds started to roll in and we decided to have a
break. The break lasted till about 1.30am when we were getting ready for
bed...the skies cleared up and the transparency became excellent!. Whew
the milky way stretched all the way from the south to the north. Seeing
how Orion was getting lower, decided to catch a quick glimpse of its
wonders. M42 was looking superb now with its wings fully
stretched...heaps of nebulosity around M42 as well. Looked at M78...much brighter than
from home and resembling a comet with a short tail more than anything.
Tried for the Flame Nebula but did not see it. Now onto Eta Carina
which was very high in the sky!
Hmmmm..in the 6", even the clumps and knots are visible. This is a
brilliant nebula stretching over a very large portion of the sky. Only the
central portion was visible in my scope operating at 56x (will have to
get a lower mag ep...say 32mm or 40mm). I could make out the
keyhole...and wait a minute....the homunculus does look non stellar. Bumped up the
mag and though I could make out the shells. Now I am not crazy or
anything but the 6" view actually looked quite good even after looking at it
through a 16"! And hey Centaurus was quite high too..time for Omega
Centauri. This was the first time I would look upon Omega with my 6". It
is a brilliant and huge glob..much bigger and brighter than 47 Tuc...a
distant second now. At 56x Omega was pretty much resolved to the core
with its chains of stars resembling skeletal arms stretch as far as the
eye could see (the 10" view was something else altogether). The glob
looked very flat (probably due to its fast spinning speed) without !
a condensed core. It looked distinctly yellowish. Very different
looking from 47 Tuc and most of the other "common" globs.
Bumping the scope north, I caught a glimpse of NGC 5128 a rather
peculiar looking galaxy also known as Centaurus A, a radio source. I have
seen this through binocs from a dark sky site but nothing could prepare me
for the view. The dark dust lane was barely visible with direct vision
but stood out like a sore thumb with averted vision. I also had the
impression that I was looking at a smaller and unresolved Omega...cool.
Also caught the edge on galaxy (NGC 4945?) in Centaurus...another
brilliant first for me appearing like a very delicate fat streak at 56x. No
mottling was seen (will have to confirm this with a second view).
As dawn was fast approaching, I had to start my hunt for all those
galaxies I had planned to see. Leo, Virgo and Coma was up as was Corvus.
First stop was M83 in Hydra...never found it in my scope for some
peculiar reason but saw three spiral arms in the 10". Looked like a miniature version of M33 in Triangulum. Next stop Leo and M65/M66 and M95/M96. As
a kid, I grew up dreaming of seeing these rather bright galaxies in my
Cometron scope...no luck. But my luck was about to change! M65/M66 was
easy in the 6" at 56x with a smaller and fainter streak north of them.
Thought I had seen M95/M96 in the ep but I was wrong after checking
"The Messier Object's" by O'Meara when home. Saw three rather faint
galaxies in the field forming a small triangle (I had a nagging suspicion
that these were not M95/M96 as they were quite faint!). Turned out that
they were some NGC's north of M95/M96. Oh well will have to hunt these
ones down on my next trip I guess.
Next stop...Virgo, Coma and Corvus. M104, the Sombrero looked brilliant
in the 6". I have seen this from home (mag 5 skies) in my 3" but the 6"
at 56x under dark skies showed something else. It was really bright and
the dark lanes was hinted at that mag. At 112x the dust lane was easy
(in the 10" it was thick enough to drive a dump truck through). Then
onto the Black Eye in Coma. Also a very easy galaxy, I did not see the
dark dust "eye" on first glance. A buddy commented that he saw it by
scanning the outer fringes of the galaxy. I tried that trick and saw it in
the 6" though it was easier in the 10". The rest of the night (or day as
the sun would rise soon) was spent looking at some ellipticals in Virgo
(M49 was brilliant in the 6") and Coma. Did not get a chance to draw
that many galaxies in Virgo as there were to many...well will have to
dedicate more time to them on my next trip...
Overall it was a very fruitful trip. Its hard to get exceptionally
clear skies in summer but we were rewarded for our patience. The next trip,
I plan to hunt down all the galaxies in Virgo and Coma and maybe try
for M95/M96 again as well as spend some quality time with Omega Centauri!

Taurus
I went in search of asteroid Vesta as it was travelling between Gamma and Lambda Taurus. The asteroid formed a trio with two
mag 7 stars that are a little above gamma and lambda Taurus. It was easy to find, the two stars were quite a white colour in comparison
to the asteroid. Vesta at mag 6.7 had a very pale yellow colour and was easy to see.
Cetus
Moving across to Cetus I went in search of M77 (mag 8.9). I found delta Cephus and moved a little to the south and there I picked
up the faint smudge of the galaxy. The central core was easily seen and a star (mag 10) a little to the right of the galaxy gave it the
appearance of having two cores. There was definitely an impression of elongation in the galaxy and bumping up the magnification using the 9mm
eyepiece gave a good view with good contrast though no real detail in the structure could be seen.
Gemini
As I was on a roll here I went in search of the Eskimo nebula, NGC 2392 (mag 8.6). I located delta Gemini and star hopped from
there. When I was in the right area the nebula was visible in the 32mm eyepiece as a small out of focus star. Increasing the magnification
revealed that this was a nebula. It was quite bright and circular in shape. The 9mm eyepiece gave the impression of an irregular
edge to the nebula but again no real detail could be seen.
At this point I was looking up at the sky and I saw a Geminid meteor streak past heading for Orion, it was very white and slow moving
with quite a short tail. I kept looking for more but that was it!
Taurus
I finished off the night by seeing if I could find M1. The last time I went in search of this nebula I couldn't see it without the
aid of a skyglow filter. Tonight without the moon the sky was dark and I tracked it down using the 32mm eyepiece. I located the area
and found the nebula easily. Its elongated shape was visible but the nebula wasn't as bright as the Eskimo nebula I found earlier.
Anyway, it was good to see this again without the need for a filter to see it.
I called it a night and was happy to have found an asteroid, nebula and galaxy that I hadn't seen before.

Eyepiece | 25mm Kellner, 20mm Plossl, 9mm Kellner |
Observing notes: |
My first trip to the Southern Astronomical
Society's dark sky site with my newly acquired 6" scope. I had an
agenda for this trip, to see all the objects with low surface brightness
that are invisible from my suburban observing site, plus to revisit some
old favourites. As the sky darkened, the first thing that caught my eye
was the "clouds" towards the south. Those were not clouds, they were
the LMC and the SMC! Boy were they bright! I have glimpsed with
difficulty the LMC from my suburban site but the SMC has continued to elude me
until now. Not much details with the naked eye but excellent objects to
scan with binocs!
Waited till the sky was much darker and started to hunt down the faint
fuzzies. First up were my two faves, NGC 55 and NGC 253, the Sculptor
galaxies (both visible from my mag 5 skies back in Brisbane). Under dark
skies, these two bright galaxies were excellent. Mottling was seen in
253 with a hint of the dark lane. 55 looked distinctly clumpy, showing
its distinct asymmetry with one end clearly brighter than the other!
Next on my list was the extremely large but low surface brightness
Helix nebula in Aquarius. I have never been able to spot this from my
balcony. The planetary was an easy catch showing up as a featureless blob in
my binocs. No hint of the central hole so visible in photographs. On to
my scope. The scope showed little extra detail with the central hole
revealing itself at the edge of perception and only with tapping and
averted vision. Rather disappointing object but at least I can say that I
have seen it!
Next up..another large but low surface brightness object, M33 in
Triangulum. Many have said that this galaxy is a good indicator of the
quality of the observing site. If it is visible to the naked eye, you have
got yourself a great site. Well, the galaxy was definitely visible with
the naked eye this night! Through the binocs, it was an oval haze
covering a much larger area than the Helix nebula. The views through the 6"
were breathtaking (before I looked at it through my observing buddy's
10" DOB that is...5 spiral arms were visible in the 10"). Traced two
distinct spiral arms. One radiating to the north and another to the south.
Cool!
Next up M31, the great galaxy in Andromeda. Also visible to the naked
eye, this galaxy was awesome in the scope. Covering a ridiculously large
extent of the FOV, I spotted for the first time its dark lane. But it
was not totally obvious...rather at the edge of detectibility. The
nucleus looked distinctly greenish and both M32 and M110 were visible (M32
visible in the same FOV). Another great object to look at!
Finally...my perennial faves 47 Tucana (boy...good resolution all across
the glob...but overshadowed by the 10".....looking spectacular like
photographs with stars resolved all the way to the core!!!!); the
Tarantula (again spectacular in the 10" with all its knots and clumps); eta
carina nebula; M42, the great Orion Nebula (large greenish wings visible in
all its glory!) with the sword of Orion (patches of nebulosity
everywhere!), M78 (a first for me too..have to try from home! Looks like the
head of a comet!!!!); M1, the Crab Nebula (much larger than it appeared
from home...spectacular in the 10" with the crab structures observed
with averted vision!). Last on the list was NGC 3132, the eight burst
nebula. Expected more out of it but was disappointed....looked a little
more like a bright out of focus star than anything else....oh well..till
next time..

Orion Nebula
Jupiter
In our current relationship to Jupiter, the moon's shadows appear well
before the moons actually encounter the planetary limb.
I started observing a bit after 10:30 MST, just getting set up. I
noticed a bump on the planetary limb, which I recognized as a moon. At
first I thought I was seeing either Io or Europa just passing behind
Jupiter. It turned out, rather than disappearing, the moon separated from
the limb. Turned out it was Io, having just traversed the face of
Jupiter. Due to the previously mentioned geometry, Io's shadow had long
passed, and I hadn't seen the moon superimposed on the planet's surface.
About 11:30 I could see the stark black shadow of Ganymede encountering
at high Southern latitude, with the moon itself still a considerable
distance from the limb.
I watched the shadow creep across (Ganyemede's moon moves more slowly
of course than Io or Europa, do to Ganyemede's orbit) for the next hour.
About 12:30 the Red Spot moved around enough for me to discern it.
Every couple of minutes the atmosphere would give me a nice glimpse,
allowing me to easily see how the
Northern belts flow around the Red Spot. I could easily split the
Southern Equatorial belt, but the darker Northern belt appeared as a
single, though lumpy band. There was a darkening in the Northern belt just
ahead of the Red Spot's longitude.
At around 1:30 AM, I finished up by catching Europa's re-emergence from
behind Jupiter, yet another surprise.
Saturn
I could easily see a wide, lighter band around the equator of the
planet, and darkening toward the poles. The edge of the ring behind the
planet just about at the limb of the planet. At about 180x, the Cassini
division was clearly visible, as well as the A, B, and less defined C
rings. At bit of the planet's shadow could be seen on the rings as they
were passing behind the planet.
At times, the A ring appear to have a bit of shading or structure, but
it was just at the limit of visibility, coming and going. Was this a
glimpse of the Encke division?

Observing notes: |
Just managed to catch Mars and the Moon before they slipped below the roof tops, made a nice naked eye sight (good in binoculars too) with Mars a little above the Moon. Whilst I was using the binoculars I tried to find M33. I swept the area a few times and thought that I'd caught hints of something but I couldn't be sure. I'm still not convinced that I've seen this yet! Next on my list was the two satellite galaxies to M31. I found M31 straight away and it was showing up well with quite a large area of the spiral showing. I moved north and found M32 (mag8.1), it looked like a small nebulous star. Averted vision made this stand out more and I was convinced it wasn't a star but indeed the galaxy. Moving south down past M31 I found M110 (mag 8.1). This galaxy was much larger and had a brighter central core than M32, the galaxy was elongated in shape with its axis pointing towards M31. Again this galaxy was seen much better with averted vision. I was happy to have finally found this trio. As Aquarius was in a reasonable position I tried to find the globular cluster M72. I couldn't see it but then Aquarius was in a region of sky that suffers badly from light pollution. To check I was in the right area I star hopped to M2 and found it. It was quite well defined but I couldn't resolve any stars. I moved back down to find Zeta Aquarius. This is a double star and is quite a tight one to split. I could only split the two mag 4.4 and mag 4.5 components at 234X magnification, there was a clear dark line separating the two bright white stars. Then as usual the clouds came rolling in, but at least I'd made a few new sightings....

Observing notes: |
Last year I was challenged to find a planetary nebula (NGC 1931 mag 10.1) in Auriga which due to its position and the time of year I had very little opportunity to find. Tonight Auriga was well placed in the evening sky and I went in search of this object. I found a group of stars near to IC 410 which led me towards the location of the nebula. I went too far and came across M36 - it was looking good tonight with many stars visible in the cluster. Star hopping from here I soon found the two stars that the nebula sits between. I couldn't see the nebula with the 32mm eyepiece. Adding the barlow I was able to make out a small smudge but nothing else. I tried various powers and found the 9mm gave the best view. This nebula resembled the view of M57 under low power - a small out of focus star. Having said that NGC 1931 was just a little larger than this and not as well defined but I definitely had the impression of a bright core with a rounded haze rapidly becoming fainter as you left the center of the nebula. I was really pleased to have found this one as its one of the faintest object I've yet seen with my telescope... Whilst in the area I looked at M36 and M38 and decided to check out NGC 1907 Mag 8.2 again. The last time I saw this open cluster the moon was out but not tonight. I could make out several more stars this time and could see a triangle shape of stars quite easily and many more stars just beyond being resolved. Saturn was next on my list and wow was this a fantastic sight. It looks a lot better than I remember from last year, I'm sure I could see a shadow on the planets atmosphere cast by the rings. If this wasn't what caused the band around the planet then it must be something in the atmosphere. I will be revisiting Saturn as it climbs higher into the sky over the winter. Jupiter was disappointing as it was still low in the atmospheric murk but I'll get it later in the year. I then looked around the sky and could easily see the double cluster and M31 with the naked eye - not bad from my back garden with all it's street lights! |

Observing Location: | Norcross, GA, a suburb of Atlanta. |
Object Observed: | Moon, Saturn, Jupiter, Pleiades, Polaris, Vega, epsilon Lyra, M57 |
Viewing conditions: | clear suburban skies, limiting visual mag maybe 3.5 to 4 |
Telescope | 6" Discovery tube style dob (old style) |
Eyepiece | Sirius plossls: 40, 26mm. Meade 4000 plossls: 26, 9.7, 6.4mm. Vixen Lanthanum 5mm |
Observing notes: |
I picked up a used Discovery dob on eBay.
The price was good,
unfortunately it suffered some damage in shipping. I'm still
learning to collimate this scope and I replaced the 6x30 finder
with a 8x50. This had led to balance issues which I fixed with
Velcro, a school kid's pencil pouch, and aquarium rocks. The
original goal of this night was to stay out long enough to let
the scope cool down, to test balance with the new mods,
to align the finder, and to see if I could get better optical
performance than my 90mm refractor with this instrument. In the few
brief tests before, that was impossible.
I was going to view in the parking lot of my apartment complex, so I
took the dob out in parts. There are trees around so I found a spot
with a fairly good east view and some westerly view. As the scope was
cooling down I spent most of my time aligning the finder first with
the moon, and then later with a star. Balance was fine and the motion
was easy, and smooth. I was using a 26mm eyepiece at the time. I took
a look at Saturn and then at the Pleiades. Under the 26mm Sirius,
stars seemed sharp and tight. Saturn was at least as good as the last
time I looked and a hint of the Cassini division was visible under
the 9.7mm Meade 4000, even though the scope had not cooled down.
I moved to be able to see Vega and Lyra, and tried to see if I could
catch M57 in a low field eyepiece. I did find it after a few minutes
of looking. After coming from a GOTO scope, I as impressed by a couple
things in the dob, the first the ease with which you could keep
objects in the field of view at higher power, and the simplicity of
moving the dob. Sometime around now I realized a lawn chair would be
nice and I fetched one. M57 was very faint, just a light patch about
the apparent size of a pencil eraser. No detail as observed in the
nebula. The moon was bright and washing detail out of the sky.
Next I tried to split epsilon Lyra. The scope had been out about 45
minutes and I was told the cool down time for this scope would be about
1 hour. With my collimation skills, the stars were not tight, they
sparkled and were a mess, but in moments of good viewing, you could
see the split at 120x.
I moved back to Saturn as the hour mark passed and the cool down time
had made a substantial difference. By now the Cassini division was
easy to see, at 120x, and the scope took magnification up to 240x
(The Vixen Lanthanum) easily. One band was visible on Saturn, but
no more. I spent some time trying to tease out others, but the
viewing conditions were not up to it. The finder alignment was
pleasing,
as the 8x50 was aligned to the point where putting a target on the
cross
hairs put it easily within the view of a 9.7mm eyepiece. This was a
definite improvement over the 90mm. You could go directly to a high
power
eyepiece and skip a low power scanning step.
I went back to the moon for a while and looked at it with low and high
power. There was a wealth of detail I'd never seen in smaller scopes.
The one thing that impressed me most was the view of the edge of the
moon. Rather than being a smooth circle, in the 6" you could see that
the edges were rough; you could see the outline of mountain peaks, and
see the depression of craters. The crater Tycho was just awesome,
dominant in the sky.
I swung the scope back to Polaris, to do a star test. Splitting
Polaris was easy, no violet haze to obstruct the view of the secondary.
The single most dominant feature of the star test was turbulence. I
couldn't see much more than that. Around this time security showed
up, wondering what I was doing. Gave the man a view of Saturn at 120x.
He was very pleased. After he said, "I'm going to have to tell my wife
that I saw Saturn. I could see the rings and *everything*."
I was about to go, but I walked the lot, and found that in a corner
of it, the tree line to the east was lower and Jupiter had risen. So,
I carefully moved my scope, chair, and eyepiece case to a good spot
and took a look. First thing I noticed was that Jupiter was more than
a spot in the finder, and that you could see Jupiter's moons in it.
The view of Jupiter was tantalizing. It was large under 120x, a big
target and easy to see. Two broad bands showed, and there was
fine structure vaguely visible in those bands. 3 moons easy to see,
there may have been a fourth but it didn't stand out. Averted vision
kept giving tantalizing hints of further bands on Jupiter itself.
By this time, I noticed that dew was collecting on the tube of the
scope. I decided to go in. This is a work day for me and I needed to
get up. Orion had risen above the tree line, and this is a constellation
I've never looked at under a scope. Later though. Maybe this weekend,
after I get a laser collimator and a UHC filter.
Other comments: I was disappointed in the views the 40mm Sirius gave
me this night, as it seemed to suffer from double images a lot. Not
sure what could be causing this. Optical performance this night was
far superior to a 90mm on the moon and planets, and inferior to the
90mm refractor with doubles and high magnification of stars. I think
the latter will clear up with better collimation.

Observing Location: | Southern NM |
Object Observed: | M15, M2, M13, M92, M27 |
Viewing conditions: | Clear, but bright moon just on the East horizon |
Telescope | Discovery 6" f/5 Equatorial |
Eyepiece | 25mm & 10mm Plossl |
Observing notes: |
Trying out a calculator program that helps point my equatorial mounted telescope, I spent a short time hunting a few Messier objects. I was racing the waning moon, which was just appearing on the horizon. M15 - Found after sweeping a bit. I guess I did a poor initial alignment, because the calculator placed this one just out of the FOV. It's an interesting object. With averted vision, I could see that this was a fairly large global, nearly the size of M13 in Hercules. However, it's intensity falls off very fast, as if it has a less dense shroud around a considerably more dense center. The central area is quite bright compared to the general appearance. M2 - Again, located just aside of the initial FOV. Appears more dense overall than M15. It doesn't appear to have the extended area of less density. Overall, more evenly illuminated, not showing the bright core visible in M15. M13 - After a re-alignment, the calculator nailed this one on the nose. It shows easily twice the illuminated diameter as M2. Like M2, it shows a gradual increase in brightness from the extremities to the core. Speckles of individual stars can be detected with averted vision. In all, has a granular appearance. M92 - Similar in appearance to M15, with a bright core (not as bright as M15), and an intensity that falls off fast as one moves from the core. Perhaps half the diameter of M13. M27 - Dumbbell nebula. The calculator nailed this one as well, appearing well in the FOV at first glance. It was easy to see, and with averted vision took on the familiar hourglass shape. No colors were detectable. I'll need to try again in a few days, as the waning moon had appeared by this time, washing out my chance at prime star observing. |

Viewing conditions: | Poor, high light wispy cloud |
Telescope | Orion Europa 150mm f/5 reflector |
Eyepiece | 23mm Sirius plossl, 6.4mm Meade 4000 plossl 2x barlow |
Observing notes: |
Although the sky looked clear there were bands of wispy cloud passing through at high altitude making the conditions difficult for deep sky objects. I decided to try a few double stars.
Pegasus
First I tried Enif (mag 2.3) it is very orange and quite large large compared to
the companion star. It was a small white star (mag 8.6) and was relatively
hard to see for the glare of Enif. A nice double with good contrast in size and
colour.
Aquarius
As I was in the area I decided to use Pegasus as a route to find M2 (mag 6.5).
This globular cluster is small but quite bright, some stars were on the edge of resolution at high power -
6.4mm and the 2X barlow. The view
with the 32mm and 2x barlow was better but no stars were resolved. M2 was quite low in
the light polluted sky hence the poor view. Still it was the first time I'd
found this object.
Cygnus
Tried for delta Cygnus (mag 2.8) and its companion (mag 6.2) - no luck though the star did
have an extended appearance at high power I couldn't split the pair.
Lyra
M57 (mag 9.4) Ring Nebula. Despite the poor conditions I could easily make out the ring shape
at medium power, moving up to the 6.4mm eyepiece it was easy to distinguish the central hole.
I was unable to get a really sharp focus on M57 tonight.
I split Epsilon Lyra whilst I was in the area using the 32mm eyepiece, the 6.4mm
and 2x barlow split the double double but the seeing was very poor at such high
power. Then along came thicker cloud and it was time to call
it a night.

Observing notes: |
My intention this evening was to have another look at comet Linear but I failed to find it. I didn't have a finder chart for the comet and I only knew that it was somewhere in Vulpecula.... Sweeping the area with binoculars failed to locate the comet. I can only assume that the moon glow hindered my attempt. Whilst searching for the comet I came across a few objects - some for the first time! Vulpecula - M27 (mag 7.3) I've seen this nebula a few times before. Tonight, even with the moon above the horizon M27 was quite bright. With the 32mm eyepiece I thought that I'd found comet Linear but then on bumping up the power with the 2x barlow I realised I was looking at the Dumbbell Nebula. It's distinctive hour glass shape was easily seen. Pegasus - M15 (mag 6.4) Surprisingly enough this was the first time that I'd seen this globular cluster. It was quite small but fairly bright. I couldn't resolve any stars at any magnification. Perhaps from a darker site with no moon some stars would be resolved. Cassiopeia - M103 (mag 7.4) I gave up looking for comet Linear by now and had a browse around Cassiopeia (the sky was darker in this area!). Whilst scanning the area using the 32mm plossl a faint meteor went right through my field of view. It was a long thin streak, dull brown in colour! On following the trail backwards it came from the region of Perseus - an early Persid? I found a faint glow near to Ruchbah (mag 2.68) and bumped up the magnification. Several stars popped into view. I used the 9mm eyepiece to give better contrast and saw the open cluster as as lazy 'S' shape with one or two fainter stars scattered around. Quite a nice little cluster. Moving down I found another open cluster NGC663 (mag 7.1). This was larger than M103 with many more stars on show. It wasn't a particularly dense cluster but it was a nice sight. I thought at one point I was seeing hints of nebulosity but no just some thin cloud moving through! Perseus - Double Cluster Whilst I was in the area I had a look at the double cluster. This showed up well with the stars gleaming against the dark sky. I have seen this cluster better during the winter but it was still worth viewing. I was getting ready to pack up (got work in the morning) and decided to have a look at the moon, it was quite low in the sky and was a warm orange in colour. I noticed a star near to the dark side and tried to watch to see if would be occulted by the moon. It wasn't to be my night, the moon dipped below my line of sight before anything happened (that I could see). Despite not being able to find Comet Linear and the moon dropping out of sight it was quite a good session. |

Telescope | 6" f/5 Discovery Newtonian |
Eyepiece | 40mm MA, 25mm Plossl, and 10 mm Plossl |
Observing notes: |
I was checking out a recently developed HP
calculator program to help point the telescope. The system requires me
to polar align, then pick a guide star (that's in the calculator).
Then set the declination to the star's declination (shown by the
calculator), and set RA to zero. From then on I can select items from the
calculator list, and the calculator tells me where to point, accounting for
Earth rotation since the selection of the guide star.
With this technique, I selected Vega for initializing, and was able to
find M13 (Hercules Cluster), M92 (globular cluster), M57 (Ring Nebula),
M56 (globular cluster), M27 (Dumb-bell nebula), and M101 (Pinwheel
Nebula). Each item (except for M27) were either in the FOV of the 40mm
eyepiece, or just outside, after positioning the scope as indicated by
the calculator. M57 fooled me, in that with the 40mm (and even the
25mm), the object was so small it was mistaken for a star. With the 10mm,
the ring was easily spotted, and right on target.
M101 (Pinwheel nebula) was easily visible, but not spectacular. I may
have better luck on an evening when I'm concentrating on observing
rather than checking out the calculator (during which time my night vision
got blasted by a flashlight).
The calculator currently holds a dozen or so guide stars (for initialization at any time of the year) and the entire Messier catalog. I can
likely double the table size before running out of memory. It's not
quite a go-to telescope, but not so far off either.
I was particularly pleased with finding M92 and M56, in that up to now
about the only globular cluster I'd routinely observed was the Hercules
cluster. I look forward to being able to view the entire catalog, now
that locating objects is so much easier.

Examined Mars, using an Apodizing screen
attachment. Was able to see "soft" images of Erythraeum Mare and
Acidalius Planum. I was disappointed at the softness of the details, given
the sharpness of the planet in general. It was a few days later I
learned that Mars is being occluded by a global dust storm.
One interesting feature was a pronounced whitening at the poles, as if
the poles were rather large. However, since then I've examined some
Hubble photos of Mars, and notice that sometimes, whispy clouds extend to
lower latitudes from the poles. Perhaps That is what I was seeing.
More recent observations show virtually no detail at all, and the
whitened area of the poles is much smaller.

Mars Mars was low to the horizon, in fact I had to view it between two houses! Despite being low and in the sky glow from Nottingham I was able to focus quite easily. I was surprised at how large the planet looked in the 6.4mm eyepiece and was a little disappointed that I couldn't make out any surface features. The planet was a pale orange in colour fading to white at the northern polar cap. I watched Mars until it disappeared behind the house. Sagittarius The upper reaches of Sagittarius were visible just above the roof tops and I concentrated on finding as many objects as possible. This was the first time that I'd been able to use my telescope in this area of sky! First I took a look at M8 the Lagoon nebula (mag 5). The right hand side of the nebula (as I looked at it) was quite a dense grouping of small bright stars surrounded by some nebulosity, moving left there was a dark patch and then two quite bright stars with quite a lot of nebulosity surrounding them. Moving north I cam across M20 the Triffid nebula (mag 6.3). There was a loose grouping of a few stars and a little nebulosity was detected. I thought that this nebula looked better through my binoculars. To the left of M8 I found a loose sparse open cluster, Cr 367 (mag 6.4). It looked a little better at higher power as this improved the contrast. An orange star gleamed at the edge of the cluster it was the only thing of note that I saw in the area - I'm not sure if it belongs in the cluster! I then found Cr 394 (mag 6.3). This is another open cluster. This was quite a dense group of stars, more so than Cr 367. Stars were easily resolved with hints of others with averted vision. Next I moved onto the globular cluster M22 (mag 5.1). This is quite a large globular cluster but it had a very diffuse appearance (similar to looking at the core of Andromeda). I tried various magnifications but I could not resolve stars in this globular. Even so it was still an impressive sight. By this time cloud was coming in from the west and Sagittarius was going down below the horizon. Looking up I saw the milky way. Many stars were visible, more so than I'd usually see. Scutum Moving north I found the open cluster M11 the Wild Duck (mag 5.8). WOW was this a beauty! There were many stars packed into this cluster, many of them easily resolved. Averted vision showed up countless more stars. This cluster seemed to be intersected with dark lanes, I got the impression of at least two lanes running through the cluster. Moving towards the edges of the cluster the star density thinned out a little. This is well worth another visit! Hercules I then had a quick look at M13 (mag 5.9) as it was quite high in the sky. The globular was quite bright and at moderate power I could resolve stars. Using higher magnification didn't reveal too many more stars. Averted vision brought a few more into view. I then moved onto M92 (mag 6.5) I usually miss out this globular as M13 is much bigger. However on this occasion M92 out did it's neigbour. I saw many more stars in the halo of this small globular cluster. It was brighter than I thought it would appear and it stood up well to higher magnification. The 9mm eyepiece revealed quite a few more stars. It was now after 1:15 and I decided to have a look for the comet Linear A2. I scanned the sky with my binoculars and there in quite an empty patch of the sky was this comet and boy was it big! I trained my telescope on the area and was impressed at the size of the comet in the 32mm eyepiece. The halo was circular and looked similar to the core of Andromeda. I couldn't make out any hint of the tail. I bumped up the magnification and from time to time I thought that I could make out granularity at the core of the comet. On two occasions I glimpsed bright flashes (the first group were very bright), the best description I can give is that they resembled sparks. I would have thought I was seeing things but it did happen twice. With the moon gaining height and
the cloud rolling in I decided to call it a night - but hey what a night!
I saw Mars, Linear A2 and six new objects!
Newsgroup discussion on the flashes / sparks that I saw in the coma of comet Linear
has offered suggestions that I may have witnessed the occultation of a star or it was perhaps an atmospheric
event. I read a report on the web that the comet did break up some more on the morning of the 14th July
so I may have seen the vapourisation of gases or ice! I'd like to think so...

Object Observed: | Mars |
Viewing conditions: | Fair, cloud-free, light breeze |
Telescope | Orion Optics Europa 150mm Reflector |
Eyepiece | 6.3mm Plossl |
Observing notes: |
Mars was firstly located using the 6x30
viewfinder and the 25mm Kellner, though which Mars appeared as a tiny but
very bright red disk. Moving up through the eyepieces, the maximum
that could be obtained without loosing the sharp definition of the
planet's edges was the 6.3mm plossl giving approx. 118x. The brightness of
Mars through this eyepiece prompted me to reach for the colour filters
(which appear to be a necessity when doing any planetary work). The
light blue appeared to give the best results on this occasion, turning Mars
into a glareless white and what appeared to be slightly gibbous disk.
As I continued to track it, Mars gradually started to reveal some very
subtle light grey patching. As I became more confident of the
permanence of these features (i.e. I was not imagining them !) I reached for a
pad and pencil to record their sizes and positions. The grey area
appeared to be C shaped, starting near the upper (South pole) and foll!
owing the planets left edge around to the lower (North) pole. The
upper area near the top of the disk was darkest and best defined, with the
rest of the grey area below being much more subtle. Following the
session, I called on my Mars Previewer II (freeware) program, to attempt
to identify what I had seen. The upper distinctive area was Mare
Erythraeum and the lower region was Mare Acidalium. This was my first
successful attempt at Mars so I would be keen to hear of any observations
made of Mars at the same date & time.
Comment: I think this object will really demand regular practice (and
good seeing) to get the best results, however I am not sure how much
more I can expect to find with a fast (f5) 150mm Reflector.

Observing notes: |
After my daughter and I built the scope in April we caught, Jupiter, Saturn, Orion Nebula, the Beehive cluster, and M65 and 66 under dark skies at our weekend home in VA. We haven't made it down there since then. In May we got a Quickcam VC for $10 and photographed Mars and the moon from DC. I recommend Cartes du Ceil (Sky Charts) a free star finding application that rivals expensive commercial packages. That is how I found everything. Also, try Astrostack software (also free) for using Quickcam images - Mars was my first attempt. This is very doable by rank amatuers. |

Observing notes: |
For once I didn't have to wait for the scope to cool down! This was my first observation of the Sun using my telescope and I was
a little apprehensive to begin with as I was using a home made solar filter utilising the Baader Solar film. The filter
is almost a full aperture filter (5.5" aperture) and it performed well. The light from the Sun wasn't as bright as that from a full
Moon and didn't hurt the eyes at all. When I looked away from the eyepiece there was no 'spots before the eyes' or anything like that
so I felt more confident in viewing the Sun.
On using the 32mm eyepiece the Sun filled about 25% of the field of view and five groups of spots were clearly visible. I went
up to the 25mm eyepiece with the 2X barlow and the Sun filled the entire field of view. What an impressive sight this was. There
was plenty of detail to be seen in the sun spots. Some were large others were made up of several spots and surrounded by countless
smaller spots. The larger sun spots had a very dark central region and this was surrounded by a lighter border that was quite
wide.
As far as I could tell the boundary between the lighter area and the dark area was very sudden, there was no impression
of one gradually merging into the other.
I used the 9mm and 6.4mm eyepieces to study individual groups of spots. It was then that I noticed that the spot near to the
limb of the sun looked like a shallow crater or depression, I've yet to confirm if this is how sun spots look or if it was a trick
of the light. One of the larger sun spots revealed that it was made up of over fifteen individual spots (there may have been
more smaller spots that I couldn't resolve) with the second part of the group comprising a single large spot. The whole cluster had
quite a long, stretched appearance.
I'm now hooked on solar observing - can't wait for the next clear day...

Observing notes: |
When I put the scope out to cool at about 8:30 pm I noticed a crescent moon edging towards the rooftops. I decided to have a look at the moon and spent almost 30 minutes viewing the moon until it had disappeared from sight. An quite a sight it was too, the sky was still light blue so there was no noticeable glare from the moon. With such a small edge to look at I didn't expect to see too much but I was surprised at the amount of detail on show. One of the large maria filled craters (I need to improve my lunar geography) showed a mountainous crater rim with an inner ridge just inside the crater featuring prominently. There were a couple of smaller craters in here too that were worth a look. I continued to work my way up and down the limb of the moon and was particularly struck by a couple of craters that overlap each other. I'm not sure if it was a trick of the light or if these craters actually look lie this but they had the appearance of a stubby footprint! Once the moon had gone I went inside until it started to get dark at about 10pm. When I came outside I swept the sky with binoculars and realised that Hercules was above the horizon and that bright star in the murk must be Vega - I was quite surprised to see these constellations! Hercules: M13 (mag 5.9) First stop was to check out the globular cluster M13. I found it straight away and it appeared as quite a bright fuzzy ball with no stars resolved at any power of magnification. Quite disappointing. Coma Berenices: M53 (mag 7.7) Next I tracked down M53, another globular cluster. This was smaller than M13 but was quite bright and was showing a mottled core with a hint of outer stars being resolved with averted vision. Whilst in the area I tried to find the galaxy NGC 4559. I thought at one stage I'd found it with just the barest hint of wispiness showing but I couldn't really be sure I was seeing anything so I don't think I can claim this one! Canes Venatici: M3 (mag 6.4) Next it was to another globular cluster, M3. This was the first time I'd seen this object and I was pleased to have found something I hadn't seen before. It has a bright, grainy core and several outer stars were easily resolved. This globular seemed quite compact but at higher powers it seemed to loose a little of its rounded appearance. Quite a nice sight, one I'll revisit. Leo: M65 (mag 9.3) M66 (mag 8.9) Next I wanted to find NGC 3628 (mag 9.5) that forms a trio with M65 and M66. I had a difficult time trying to locate M65 and M66. I eventually found them and they were oh so faint! Much fainter than the last time I'd viewed the pair. M65 showed up as the slightly brighter of the two but M66 definitely gave the impression that it was larger in appearance. Try as I might I could not see NGC 3628. Next I tried for a few galaxies in the Virgo cluster but I failed to spot any of these either! Lyra: M57 (mag 9.4) To cheer myself up I went in search of the Ring Nebula and found it straight away. As Lyra was still fairly low in the sky I had trouble getting sharp focus but I could clearly see the ring shape and from time to time I could see the hole in the middle. Hercules: M13 (mag 5.9) By now it was close to midnight. It was then that I noticed Hercules was much higher in the sky and I decided to have another look at M13 and boy was I glad that I took the trouble. M13 looked like it was resolving in the 10X50 binoculars! So I turned my scope back on it and WOW! This has to be the best I've ever seen M13. With the 6.4mm eyepiece I could see countless stars surrounding the cluster, almost like a cocoon of loose stars. Many stars towards the core were resolved giving the hole object a 3D effect. I spent quite a while just taking in the view - I wish I could have taken a picture... Not a bad nights observing... |

Sighted in on the double star in the handle of the big dipper. (After showing the neighbors Jupiter and three of its moons. Able to see two bands without filters on the planet itself.) Worked my way along to Phad and then started looking around. Closed in on a dim slightly reddish spot. Best view was with a 2X barlow and my 12.5mm EP. But it was still just a spot. Wasn't sure which object it was but after referring to Charts de Ciel and using the left to right and up to down aspects to place things as I saw them in the scope I feel pretty sure that it was M109. Which is surprising. |

Telescope | Orion Optics Europa 150mm f5 reflector |
Eyepiece | 25mm Kellner & 6.3mm Super Plossl |
Observing notes: |
Despite the clear conditions, the central
trapezium of Hercules was not an obvious formation. It was located by
starting at Alpha Bootis (Arcturus), moving left to Epsilon Bootis, and
left again to Alpha Coronae Borealis (Alphecca). Looking left and down
slightly from the backward ‘C’ of Corona Borealis, the Diamond of the
4 central stars of Hercules was found. Using low power (25mm Kellner)
the scope was pointed at Eta Herculis, and a line toward Zeta Herculis
was followed until M13 came into view. Gotcha ! The bright circular
‘smudge’ of M13 alongside white pin-pricks of neighbouring stars, made it
instantly recognisable. Inserting the 6.3mm Plossl eyepiece (118x
magn.) gave the optimum viewing. Use of the 2 x Barlow with this resulted
in too much loss of light and definition. I found that occasionally focusing on the nearest star, and moving back to M13 ensured the best
viewing. I found that M13 benefited from prolonged study, with so!
me individual stars starting to resolve after the first minute or so.
Very brief glimpses of granulation were also seen around the centre of
the cluster.
Comment: All in all, my first study of M13 was well worth dedicating
an observing session to. M13 will certainly be worth re-visiting in
the coming months under better conditions and when it is higher in the
sky.

Coma Berenices
As the Moon was so bright I didn't hold out much hope of finding anything but I gave it a go.... My first stop was in the Coma Berenices cluster. This looked good in binoculars showing as a group of bright stars in a large open ended wedge shape. I used a star chart to try and view some galaxies in the area but the moon was too close and too bright. I gave that up as a bad idea and went in search of M53 (mag 7.7). I tracked it down by moving from Gamma Coma Berenices to Beta Coma Berenices and finally across to Alpha Coma Berenices. From here M53 was visible in the 32mm eyepiece as a faint ball with the edges gradually diffusing into the surrounding sky. I couldn't make out any stars but then I didn't expect to see the cluster at all! I viewed this cluster at various magnifications and suspect that I may be able to resolve outer stars if the moon hadn't been present. There is another globular cluster close to M53, it's NGC 5053 (mag 9.8) and is about half the size of M53. Try as I might I couldn't see this object. Ursa Major I then decided to have another go at trying to find M81 (mag 6.9)and M82 (mag 8.2). I've read so many reports at how bright these galaxies appear and astronomers using equipment with less aperture than my scope have successfully viewed the pair. I read a report on Neale Monks web site on how he tracked the pair down. I followed his advice and WOW there they were! At last.... Here's how I found them. I followed a line up from Dubhe until I reached the star 23 UMa mag 3.67, I then moved to the left until I came across a small group of stars forming a triangle (8 rho UMa mag 4.76, 11 Sig1 UMa mag 5.14 and 13 Sig2 UMa mag 4.8). Following a line down from 11 Sig1 through 13 Sig2 I came across M81 and M82 in my 32mm eyepiece. They are bright and I'm not sure which I saw first - they were 'just there!'. M82 impressed me the most. It has a very distinctive elongated shape and I was surprised at how bright this mag 8.4 object actually was even with the Moon washing out the sky! Moving down from M82 I found M81. It appears much larger in size and has a more oval / rounded shape with a distinctive central core. After viewing this object for some time I could make out faint hazy outer layers of the galaxy. I'll be back to visit this pair the next time the moon is out of the way. Both galaxies stood up well to high magnification but didn't show up any extra detail. |

Observing notes: |
Took ages to find. Finally resolved a faint
smudge, but with a pollution filter and averted vision some very faint
structure was visible after a few minutes study.
Faded in and out (assume due to high cloud)
Comment: I real treat and encouraging as this is a 10th mag object.
Shows what you can do with a 150 and a bit of patience.
Viewed this star initially whilst trying to
find nearby galaxies. Returned after reading notes in star atlas, that
this is a particularly nice binary.
The pair were easily resolved at high power, the primary being markedly
brighter than its companion, as well as more golden in colour.
I have read that this pair can be challenging, but the 'scope had no
problem.
Comment: A nice "tourist spot" and one I will definitely return to if
anyone comes round wanting impressive views through my 'scope.

Observing notes: |
Auriga Jeff Barbour asked if I'd seen NGC 1931 - I haven't so I went in search. I located a grouping of stars which resembled a small plough shape and star hopped to IC 410 (mag 7.5). In my 32mm eyepiece this showed a couple of small bright stars and what looked like a small bright area of nebulosity surrounding them. I spent quite a while looking at this object with various magnifications (32mm gave the best results). When I'd finished I'd somehow convinced myself that I'd found NGC 1931 - oops! Whilst in the area I also picked up M36, a dense grouping of stars which showed up well and M38 was also a nice sight. Ursa Major I then moved onto Ursa Major in search of some galaxies. I star hopped from Alkaid (last star in the handle) and was sure I was in the area where M51 (mag 8.4) and NGC 5195 (mag 9.6) should be. I couldn't make them out. I was scanning the area in the 32mm eyepiece when I caught sight of M51 with averted vision. After a few minutes I could see the cores of M51 and NGC 5195 clearly and plenty of light grey fuzz surrounding them but no real detail in their structure. Higher magnification did nothing to enhance the view but I was thrilled to have found these two at last - I've been looking all winter! I then went in search of M101 (mag 7.9). I used Alkaid as my starting point for the star hopping and thought that as it was brighter than M51 it would be easier to see. Wrong! I again landed in the area where I thought M101 should be, all the stars on my chart matched up. I could see M101 with averted vision using the 32mm eyepiece and it gave up a small dim central core, much smaller than M51 and NGC 5195 who now seemed to be very bright by comparison. As I couldn't see much I moved on... might catch it another night and see if its improved. Cancer I then had a look at M67 (mag 6.9). What a great open cluster this is. I've often looked at the beehive cluster and never bothered with M67. I was surprised at how rich in stars it was. The cluster seemed to be split into two with a dark band separating two areas of the cluster. It resembled a main grouping of stars with what I'd describe as an arc of stars to the side of the cluster as I looked at it. Auriga On checking the charts I'd prepared I realised my mistake in not picking up NGC 1931 so I went in search of it. Try as I might I could not see it. I'm sure I was in the right area but my efforts were thwarted by clouds that came rolling in - maybe next time! |

Viewing conditions: | Fair 4.2 |
Telescope | 6-inch Orion XT6 |
Eyepiece | Panoptics, Naglers, Radians |
Observing notes: |
With the moon increasingly becoming a factor, I knew that I had
better take advantage of the clear and dark early morning hours while
I still could. You know what I mean - get that last photon fix before
the next new moon period frees us all.
There were high and mid-level clouds both to the east and the west,
so I decided to use my quick look setup, rather than haul the big 10-
inch scope out. The clouds from the west in particular were
reflecting the big city light across the entire sky. This I knew
would make galaxy observing difficult. Nonetheless, the brighter
galaxies would be visible in the 6-inch.
The highlight of the morning was the view of M64, the Blackeye galaxy
in Coma Berenices. This galaxy is relatively easy to find because it
is far brighter than anything else in its vicinity, so it can't be
easily mistaken for another galaxy. I must admit that despite my
penchant for galaxies, dust lanes have always been difficult for me
to detect (except for M31 and M104 of course!). Even though M64 has
one of the brightest dust lanes visible to small scopes, I still had
a really tough time seeing it, even with averted vision. Still, the
view overall was grand. The galaxy has a bright-extended oval shape
to it, and was easily visible in the 6-inch scope despite the poor
conditions. The view was nice at 55x (Panoptic 22) as well as at 102x
(Nagler 12)
I next went to NGC 4565, the beautiful edge-on also in Coma
Berenices. Unfortunately, the view today was disappointing. Yes, it
was visible, but it was too faint to capture the galaxy in its true
grandeur. A 10-inch scope really shows this one off, by the way!
I took a brief detour from galaxy observing to get my first glimpse
of the globular M3 of the season. Hmmmmm....nice but not as nice as
usual. Just another reflection of the bad sky conditions (pun
intended).
Canes Venatici was directly overhead, and still sufficiently free of
the encroaching clouds, so I turned my scope in that direction. Near
the border with Ursa Major, is M106, a really nice bright galaxy that
doesn't get the attention it deserves. It is very bright, and fairly
good size, with an oval, slightly elongated shape. The spiral arms
are not visible with a 6-inch scope (at least not to my eyes), but
the view is quite satisfying.
M94, also in Canes Venatici, is fairly bright and round in shape,
although a great deal smaller in apparent size relative to M106. In
fact, it looks more like a distant but very condensed globular
cluster in my 6-inch scope at 55x.
M63, the Sunflower galaxy (Canes Venatici) appeared a bit fainter
than I previously recall it in my 6-inch scope. Darn...I was looking
forward to seeing some detail in this galaxy, but there was none.
Only diffuse patch of light.
M51 Whirlpool galaxy (and NGC 5195) didn't look all that bad, but
with the conditions I was facing, combined with only 6-inches of
aperture, I had little or no hope of seeing the spiral arms. Under
VERY good conditions, I have detected the arms with averted vision in
the 6-inch. However, I'm sure that my mind makes up some of the
image, as I have seen the arms with larger scopes.
OK, now it was time to move on to....whoa!! What's that? Nuts. The
clouds had taken nearly the entire sky. Oh well, time to hang it up.
I'm still glad I got that last look before the next new moon cycle.

Orion
I then tried to find NGC 2194 (mag 8.5) and NGC2141 (mag 9.4) but failed to see anything. I suspect the
moon wash washing the sky out to much for me to see these two.
I then checked out Sigma Orionis, a nice easy triple with the 32mm eyepiece and moving up to higher
power I could make out a fourth star in the grouping - a nice sight.
Monoceros
I next found Cr 106 (mag 4.6), if I hadn't have known that this was an open cluster I wouldn't have given it a second glance!
It was quite sparsely populated forming a wedge shape of stars similar to a capital 'A', I saw about 8 or 9 stars in this cluster.
Next was Cr 107, this had even less stars than Cr 106! I could make out 5 stars in a rhomboid pattern! Cr 104 (mag 9.6) next to
Cr 107 showed a grouping of four stars, on checking my charts I'm not sure that these stars make up part of the open cluster.
Moving down I came across Cr 97 (mag 5.4), this again had few stars, I counted five but at least they were grouped a little
closer together!
Moving down further I came to NGC 2251 (mag 7.3), now this is what I call an open cluster! It was elongated in shape and at least
a dozen or so stars were easily resolved. Several other stars were moving in and out of resolution and more were giving the cluster
a nebulous look. A nice sight and one I will return too.
Finally I came too NGC 2264 (mag 3.9), another nice open cluster with several pairs of stars grouped around star 15 monoceros.
There were at least fifteen to twenty stars in this cluster that were quite closely packed together. I could see no sign of nebulosity
around this star.

Observing notes: |
Venus
Venus was extremely bright in the 32mm eyepiece. I used the Moon filter to cut down the glare.
I bumped up the magnification by using the 6.4mm eyepiece and Venus although a reasonable
size in the field of view revealed no discernable
detail but the phase of the planet could be clearly seen. I'd estimate it was about 60% illuminated.
Auriga
Next I tried to find a few open clusters in Auriga. I found them using binoculars and homed in on
them via a grouping of three double stars all in line - they're very distinctive. From here I quickly found
M38. This is a large open cluster with many stars to be seen and these are surrounded by a
gray misty
region which I took to be stars that I couldn't resolve.
I then moved south and found NGC 1907. This is very close to M38 and was easy to find as a pair of stars sit
directly above the cluster (as viewed through the eyepiece). First impression was that this cluster looked
like a nebulous patch. On using the 9mm eyepiece several stars sprung into view with a few others just staying
beyond resolution. This cluster although small looked like it contained many stars.
I then star hoped to M36. This open cluster appeared to be about 25 - 30% the size of M38. There were 8 - 12
bright stars forming a wedge shape with many other stars to faint to resolve, they gave the cluster a nebulous
appearance.
Cancer
I then found the beehive cluster (M44). There were many bright stars visible in the field of
view of the 32mm eyepiece, I counted around 50 stars in the cluster. They were very bright against
a reasonably dark background (the Moon was up by now and lightening everything up).
Gemini
Next on my list was M35 a large open cluster in Gemini. Many stars were resolved varying in magnitude
down to those that were beyond the capabilities of my scope. Again I think the moon was restricting
the number of stars I could resolve. It was still a nice sight.
Canis Major
Finally I turned my scope on M41. This open cluster was low down in the sky and in the sky glow from
Nottingham. As a result I could only make out the brighter stars in this cluster. There were quite a few
stars on view fairly well spread apart. There was no chance of seeing any fainter stars as the sky was
very light in this area.
Also during the session I viewed favourites like Jupiter, Saturn, the Orion
Nebula and the Moon. Whilst viewing Saturn I managed to see two moons Titan and
Rhea. The Moon made it impossible to see any other moons. In moments of
steadiness in the atmosphere I'm sure I saw the Cassini division in Saturn's
rings.

Newtonians are not common. I built mine myself and optimised it for planetary

Observing notes: |
M42 / M43
Clear conditions gave excellent view of this showpiece Nebula (and
neighbouring M43) without filtration. 6.3mm plossl sharply revealed the
tiny Theta Orionis trapezium at the centre of the blue-white gas clouds.
Addition of the 2x Barlow gave closer but much less sharp view. The
9mm kellner gave the best overall views of M42/M43. I always find the
incredible detail within M42 to be a big time-sink and tonight was no
exception.
Later swung scope onto Zeta Orionis (Alnitak) in attempt to locate B33
Horsehead Nebula. Did detect a hint of nebulosity around Alnitak but
B33 remains ever elusive!
Jupiter
Have made several recent observations of Jupiter & Galilean moons under
less favourable conditions. Main aim was to compare surface detail
under Green and Blue filters, using the 6.3mm Plossl. Whereas Jupiter
looks distinctly odd with the green filter, the darkening of the SEB and
NEB and detail of irregularity at their boundaries is immediately
obvious. Momentary hints of the more elusive NTB were sited as was some
darkening of the NPR and SPR Polar Regions. Switching to the Blue filter,
Jupiter looked far more natural with the distinctive earthy-red
colouring of the NEB and SEB. However, lesser details appear to be overcome
by the increase in the brightness of the Planets disk. More lengthy
sessions (preferably whilst seated !) observing Jupiter with these
filters are intended.
Saturn
A similar green/blue filter comparison to the above was made using the
6.3mm Plossl with the 2 x Barlow. The main observation made was the
slight increase in contrast between the shades of the lighter A-Ring and
darker B-Ring. The Cassini Division itself was not clearly visible
under either light filter.
An attempt was made to locate the M51 & M101 face-on galaxies in the
vicinity of Alkaid and Mizar within Ursa Major. Even with the 25mm
Kellner to hand, this became a fruitless and frustrating exercise
(especially as I was by now starting to loose all feeling in my fingers due to
the extreme cold!). Stopped observing at this point. I think it is
time to become more familiar with the setting circles !

Observing notes: |
I went out to see Jupiter, because my star atlas (XEPHEM on Linux)
indicated that it would be an interesting evening. Io was in transit,
and the Red Spot would be visible. According to the atlas, the two should
be physically close together.
When I got the scope set up and cooled down, I
was greeted with surely a rare event. The stark black shadow of Io was
just at the trailing edge of the Red Spot, slightly North of its
center. This entire display was just rounding into view, being perhaps 30 degrees
from the planet's edge. I could also see some division in the Northern
Equatorial belt, and some irregularities in its width. Further North
was clearly visible a much thinner band. Further North yet was
occasionally visible another thin band, which at times seemed to merge with the
darkening of the Northern cap. I expected the Red Spot to pull away from Io's
shadow, but was surprised to find that Io overtook the Red Spot. I could never
actually see Io itself.
Further consideration convinced me that while
the orbital period of the Red Spot is shorter, the tangential velocity
of Io is faster, and head on like that, Io wins the race. A very
unusual and entertaining evening at any rate.

Observing notes: |
Began with lunar observations near terminator at x126 (Vixen 9.5mm) with #11 filter.
Plato and Montes Alpes very well resolved. Under suitable illumination,
three white patches can been seen in this scope at the
sites of Plato's craterlets. Nice resolution of Copernicus' terraced
walls and the Alpine Valley.
Wrinkles on maria very clear. This scope performs very well on the moon
at x126-x200.
Jupiter
at x200 (UO 6 mm) showed clear, brown north and south equatorial belts.
The southern belt was clearly seen as double.
North and south temperate belts and polar regions were also resolved.
Festoons not evident in the equatorial zone. Great Red Spot has not
been seen yet but a transit of Io's shadow was seen at x200.Irregularies
of the northern equatorial belt were
seen.#11, 58 or 80A filters reduce glare but increase contrast only
slightly.
Saturn at x200 showed bright equatorial belts, dark polar region
and Cassini division completely around planet.
C ring not seen. Conclusion from planetary observations is that I
expected a bit more contrast and detail to be visible in this scope with its
18% central obstruction and fully baffled tube. However,
its total cost was only about $450 Canadian, and upgrading
significantly would be expensive.

Observing notes: |
The only reason I went out with my scope was
that I wanted to try out my home made extension tubes. The clouds were
thick and only for a minute or two, at a time, I could observe the
planets before the clouds covered them again.
But the tubes worked great. I estimate I got a magnification of 450x
using my 290mm (works like a ~4,5x barlow) tube and around 320 with my
195mm (~3,5x barlow). The images were blurry but very bright and BIG. I
could see great detail on the moon but not on the planets.
Next time I will try them when the sky is clear and hope I will get
nice images on Jupiter and Saturn, and try out my new 360mm tube (5x
barlow!).
Interested im making an extension tube look here:

Viewing conditions: | Fair -- 7 of 10 |
Telescope | 6" f/5 Discovery Equatorial |
Eyepiece | 10mm Plossl with 3x Barlow |
Observing notes: |
I've found that surprisingly, with
meticulous alignment, the f/5 telescope
does a fine job on planets. In observing Jupiter, I was able to easily
make out the two largest equatorial belts, plus a much thinner band just
north of the Northern equatorial belt. The Southern band appeared to separate
into two belts in places. Irregularities in both equatorial belts were
visible. The Red Spot was clearly visible (though small) during
atmospheric clearings,
showing as a pale tan oval disrupting the Southern equatorial belt.
The poles were visibly darkened. All in all, a level of detail I didn't
expect to see with such a short focus telescope. Overall magnification was
about 225 times.
Saturn was striking also. The rings are highly tilted right now, and
in atmospheric clearings, the Cassini division is easily visible. The
Crepe ring is noticible as the rings cross over the planet. An obvious
broad, bright band envelopes the planet's equator, with a darker yellow-brown
extending to the pole. I've been able to spot 6 of Saturn's moons with
the 6" -- Iapetus, Titan, Rhea, Dione, Tethys, and occasionally
Enceladus.
I think I should be able to just see Miranda at just at 13th magnitude,
but can't confirm a sighting yet.
Comment: I've found the 6" f/5 telescope to be a very frugal
competitor with the popular 8" SCT. It is even more
portable, sees within about 0.7 the magnitude of the 8", gives
75% of the resolution (the atmosphere usually denys
that anyway), and gives much more striking wide field
star views. All at less that 1/3 the price.

Observing notes: |
I recently received 2 new eyepieces so I have
constantly checked the sky in hopes that it should be just a little
clearer.. and today it got!
But it just became a brief look.
I started out with Jupiter using only the zoom at 24mm (31x) and was
very pleased by the image quality and had to put on the dustcap to see
the details. Then I increased the magnification to the max magnification
(8mm), and can say that the sharpness still were great. Could see the 2
major "stripes" but didn't notice anything else (have only observed
Jupiter once in 83x as highest before).
I added the 2x barlow and now could go up to 188x (this time without the dustcap :)). Damn I must say.. I have never seen anything that
beautiful. The amount of details I could see was to much. I didn't see the
Great Red Spot but I think it was on the other side.. but can't confirm
it.
After looking at Jupiter for a while I turned the scope against Saturn.
What can I say.. It looked even better (160x-188x). I wish I could
magnify more :) Could see the gap between the rings (don't know the name).
Great!
After using the Zoom I must say that im very pleased with it! Works surprisingly
good with my f/5 scope.
After the great planetary views I wanted to try out the 40 mm plossl.
What couldn't be better than Plaides?! Very nice.. I can se around
50-70 stars (estimated) and I can cover the whole "nebula". Clear and
sharp..
The last observation im doing is on M31. I must admit that I have had trouble to find it before, but after using SkyMap (www.skymap.com) a
while I could find it instantly. The view didn't surprise me, because I
was expecting a diminish looking blob.. and that was all I got too, but
the viewing location wasn't the best ether (1 streetlight behind me, 2 ahead and my
neighbours Christmas lights in the trees). But I was glad that
I found it. Actually I caught M110 (or was it M32??) at the same time,
and I could se IT clearly.
Next time I will transport my scope to a darker location for some serious observation.
Take Care!

I am new to astronomy, yet after 1 hour of searching (my finderscope is not set up right) i found the Orion nebula. It was not what was expected, then again i am not using Hubble.

M1
Crab Nebula
I began the nights observing by looking for the Crab Nebula (M1 - mag 8.4) in Taurus
using the 25mm eyepiece with the 2X barlow giving 64X magnification. I've
never found this nebula before and by using quite a detailed star chart to navigate my way
to where the object is located I found out why! It is very faint even with averted vision I
couldn't be sure I saw the nebula. I tried with a sky glow filter (that I've got on loan)
and it stood out more but I couldn't make out any detail. It is larger than M57 in size
and was slightly oval in shape with diffuse edges, higher magnification didn't help bring
out any detail. The object was very difficult without the filter.
NGC 1545
I've been meaning to locate NGC 1545 (Mag 6.2) for a while and took the opportunity
last night as Perseus was high overhead in a dark area of sky. The open cluster was easy to find. It's quite
a large cluster with a good grouping of bright stars that were easily resolved. It made a better
impression (in my opinion) than M36 or M37 in Auriga. Worth checking out.
IC 434
Contains horeshead nebula(B33)
As I had the sky glow filter I went after more nebula. Zeta Orion was the next target and the
nebula that surrounds the star (at high power (250X) I think I could see 3 or 4 stars here - my scope
needs collimating and there was a lot of flare from the stars at this power). I started off
by using the 32mm plossl with the 2X barlow. My first impression was there was nothing to
be seen and that my eyepiece had fogged up. Disappointed I moved onto another star in
Orion's belt
- no fog! I moved back to Zeta and there was the fog again! I'd found the nebula but I couldn't
make out any structure or shape. High power did nothing for the view. Orion was quite low in the sky
perhaps if it was higher the view might be better. One to check out later in the year.
M42
Orion Nebula
Next target was M42 and wow was this impressive in the sky glow filter using the 32mm with the
2X barlow. I've never seen so much of this nebula as I could with the filter. From the main area
around the trapezium the nebula seemed to arc up tapering off to a point. The main part of the nebula
was bright, there's a grouping of stars in a line that sit on top of the nebula that follow the
beginning of the arc. The whole view almost had a 3D effect and kept me engrossed for ages. Higher power showed more detail in the nebula around the trapezium where cloud structure could be seen.
M43
Just below M42 I could see M43 (Mag 9.0) which is a detached part of the Orion nebula. The split
between M42 and M43 was easily seen using the filter. Without it I was struggling
to make out M43.
M43 is quite small and didn't show up much detail but I could easily see it.
M35
I finished off the evening by finding some more open clusters in Gemini. M35 (mag 5.1) is a large
open cluster with many stars easily resolved. It was a little larger than NGC 1545 I'd found
earlier in Perseus and had a denser grouping of stars, there were many faint stars resolved
and I imagine more would be seen in a larger aperture telescope.
Cr 89
Just to the south of M35 is Cr 89 (mag 5.7). This is quite a loose cluster that doesn't
contain as many stars as M35 and could easily be overlooked against the background stars.
Having said that, once you've found it you know its a cluster and not just background stars.

Eyepiece | 32mm Sirius Plossl, 25mm + 9mm Kelner, 6.4mm Super Plossl and 2X Barlow |
Observing notes: |
As the Moon was so prominent in the sky - slap bang between Jupiter and Saturn - I decided to have a look just to
see what was on view. I forgot to bring my moon filter out and ouch was the moon bright! I could make out plenty
of detail in the crater rims at 50X (32mm with Barlow) and spent some time
just taking in all the sights. I didn't
spend too long on the Moon as Jupiter was 'calling'....
The last time I had the opportunity to observe Jupiter was well over a year ago - WOW has it increased in size!
I was expecting to see a small disk and the moons when using the 32mm eyepiece. Not so, I saw quite a large disk
with very faint bands and three moons (one must have been behind Jupiter). I instantly put in the 25mm with the
Barlow giving 64X magnification. The cloud bands were very distinct as was the southern polar region - it appeared as a
gray murky colour.
I then tried the 9mm out with the Barlow giving 178X magnification. This was a
truly incredible sight. Jupiter looked
enormous in the eyepiece, bigger and brighter than I've ever seen before. The equatorial cloud band was stunning,
I could even make out a ragged edge to the cloud band! I didn't see the Great Red Spot but I'm not sure if it was
on show when I was observing. As I didn't expect to see such great views I didn't look up where the Red Spot would be.
Next was the 6.4mm eyepiece and the Barlow giving 250X magnification. This was not so good. The wind was making my telescope bounce around
and focusing was hard work - keeping Jupiter in the field of view was near impossible. I persevered and for a second
or two I got an incredible view of the planet with other cloud bands tantilising close to being in focus then the wind
would gust and I lost it again!
I even tried to use a broad band filter with the 9mm eyepiece and Barlow and it gave some interesting results as
the glare from Jupiter was reduced and contrast improved. I could make out quite a lot of detail in the cloud band.
It had a mottled appearance and the ragged edge was even more distinct. The southern polar region also displayed more
banding.
I must have spent an hour looking at Jupiter! Time just flew by...
Saturn was also spectacular. The last time I saw Saturn the rings weren't so
prominent. Tonight they were there
in full display. The planet appeared to have sunk down into the rings as the rings were visible right around the planet.
The last time I looked the planet obscured part of the ring system.
I couldn't make out much detail in the rings or the planet - the wind was getting stronger and making viewing difficult.
However, I did see Titan above and to the right of Saturn and three faint stars / moons ? down at the 4 to 5 o'clock
position. I'm not sure if these are some of Saturn's smaller moons or if they were stars? On checking my planetarium
software I can confirm that I saw Dione (mag. 10.4), Rhea (mag. 9.6) and Tethys (mag. 10.2).
Next I decided to have a look at M42. What a wash out! The moon had completely obscured the nebula! The day was saved by
the broadband filter, it increased contrast enough to allow me to see the shape of the nebula. I bumped the power
up until the nebula filled the whole field of view and I could see all four of the the trapezium stars. In fact I'm
not sure but I may of got a hint of other stars in the trapezium too but the scope just wouldn't stay still long
enough for me to confirm this....
Frozen solid I went in feeling happy at what I'd observed.

Eyepiece | 25mm with 2x Barlow |
Observing notes: |
My 1st letter to this spaced-out group:
General viewing. A friend and I took our scopes to an open hilltop
that's about 90 miles NW of Chicago. I have a 6" Edmund Scientific
Newtonian Reflector (c. 1974) with an Equatorial base, and my buddy has a brand
new Orion 8" reflector on a Dobsonian base.
We had high cirrus early, streaks of dense clouds that obscured half of
the sky. But I knew that it would clear out (hoped it would!) and told
everyone to have patience. (I'm a hang glider pilot and pay close
attention to the weather.) The 4-5 others there, friends all, stuck around
and by 8pm the sky had cleared enough to genuinely start.
For the new folks, I had them look through my 12x50 Bushnell binoculars
-- mounted on a tripod with a swivel head -- at The Coathanger, The 7
Sisters, and a couple of other binoc sights. This whetted their interest
and we went to the scopes, hitting M31 first (Andromeda). Using the
Barlow and my low power eyepiece, I'm able to fill the view with this
grand sight... good for me but a little over the "spectators" heads. So we
hit Jupiter and Saturn and had them literally and physically jumping up
and down in excitement.
It's cool to see people get turned on by the glories of the heavens. I
get turned on by these events by finding new things every time. For
example, I saw the Ring Nebula M57 for the first time. Got to see the soft
ring with a dark spot. It's easy to find at the bottom of Lyra but I
could never find it with my binoculars.
After several hours I began to critically view the differences between
my old 6" scope and the 8" Orion. I can honestly say that I'm thrilled
with this giant tube. The image is tremendous, so much so that my
friend tried hogging my eyepiece. And it's definitely a superior view
compared to a neighbor's 10" Meade, though his is more stable.
This winter I'll be getting the mirror re-aluminized ($25.00) and
modifying things to make the whole thing more portable.
PeterB
Comment: There's so much to see and catalog. With binoculars I was
totally taken aback when I first saw M8 in Sagittarius. What a beautiful
sight! During the 3 hours on July 2 in Rantoul IL, I went back to this
object -- the Lagoon Nebula -- about every half-hour. Stunning!
Large scopes are fine, I'm sure, and I'll continue to seek one out, but
for now I'm pleased with my 6".
Some recent objects: M36, M37 and M38 in Auriga; M57, the Ring Nebula
in Lyra; M52 in Cassiopia; M81 and M82 in Ursa Major.

Observing notes: |
As I reviewed my log a few nights ago, I realized
that I have not recorded an observation since March, and I haven't done anything more than
take a 5 minute look at the moon to show someone! Such is the nature of summer I guess. It
didn't help that it rained nearly continuously this summer in Eastern
Pennsylvania, but at least it was cloudy the rest of the time ;)
Well, fall tends to bring clear skies to these parts, and the past weeks have not been a
disappointment in that regard. i finally made an appointment with myself to spend a couple
of hours at the eyepiece on Monday.
Lyra was high in the sky when I started so I shot for the ring to "warm up". Well at least
I was able to find it! It popped into view and was easily made out as a smokey doughnut. I
then went searching for M56, also in Lyra. I had to hunt for this devil for quite a while.
This is quite a dim cluster and not very impressive in my 6". Impossible to resolve into
stars. From there I hopped over to Cygnus to look at a couple of clusters right in the area
of Gamma. NGC 6910 is an easily found cluster in the same field as Gamma, just North. This
loose cluster has numerous faint stars and a tiny asterism that looks like a
coathanger. M29 is a completely unimpressive cluster about a field south of Gamma.
Difficult to separate from the background stars of the milky way. Moving on to Aquarius,
I re-aquainted myself with M15 and M2, wonderful, bright globular clusters. Easy to
find
and well resolved into individual stars in my scope. Then it took me the better part of
20 minutes of searching to find M72. This globular cluster is a nearly invisible smudge,
very very dim and small. Nearby M73 is a stretch to consider a cluster at all. What
was
messier thinking with this one? On to the Saturn Nebula. This planetary is very bright and
appears nearly stellar at 50x. be careful as it is easy to overlook because of this. At
higher powers, it became somewhat elongated, although it never appeared to have "rings".
I did not observe it at any more than 100x.
Eventually realized that I was loosing feeling in my fingers...one of the drawbacks to
autum :) Satisfied, I packed it in.

Observing notes: |
I've just acquired a 32mm Sirius plossl and tonight was the first chance that I've had to use it. I started by sweeping along the Milky Way from Perseus to Cassiopea. Wow, what an incredible view this eyepiece gives. It has a huge field of view, stars were sharp and focused right to the edge of the eyepiece and the contrast was excellent. In Perseus I soon picked up M34, it looked much better than I've seen on previous occasions and stars were clearly resolved. I used the 9mm to take a closer look but I lost some of the detail in the cluster as I couldn't get a sharp focus on the cluster. Whilst I was in the neighbourhood I had a look at Almack in Andromeda. Using the 9mm eyepiece this star was easily split into its two components, an orange and blue pair. The orange star was the larger of the two and reminded me of Albiero in Cygnus. It was a nice sight. Moving back up through Perseus I came across NGC 869 and NGC 884, the double cluster. What a fantastic sight this made in the 32mm. It was miles better than any view I'd had before using the 25mm, so many more stars were visible and the improved contrast made them stand out so much better. Continuing along the Milky Way up into Cassiopea I had a good roam around just taking in the view - I had no idea what clusters I was looking at - I just enjoyed the sight. One prominent cluster came into view and I identified this to be M52. This is quite a compact dense grouping of stars and was a glorious sight in both the 25mm and 9mm kelners. I swung over to Cygnus and had a look at M29, this looks much better a lower power as there are so few stars in it. After looking at a few open clusters I moved onto Lyra to look for M57. I found it quite quickly with the 32mm eyepiece. I popped in the 25mm and lost sight of M57! On replacing the 32mm eyepiece I could clearly see M57 again! I used the 6.4mm to have a closer look at M57 but was again unable to get a sharp focus - must clean the eyepiece. I dropped down into Vulpecula and picked up M27 quite easily in the 32mm, higher powers gave better results. On swing across to the other side of the constellation I managed to fit the whole of the 'coathanger' asterism into my field of view - a great sight. Moving across to Hercules I picked up M13. Now I've never been able to resolve stars in this globular cluster but this was the first time that I've viewed this object so late in the year. Well there it was, using the 6.4mm eyepiece I could resolve stars, it had a very granular core with many stars resolving towards its edges and many more just away from the core. I looked at this cluster for quite some time. It really had lived up to it's billing of one of the best globular clusters. I'm glad I took the time to look at it again. My only regret is that I didn't buy a 32mm eyepiece years ago! |

Eyepiece | 26 mm Plossl (48x) also Meade narrowband nebula filter |
Observing notes: |
I previously posted a report on the veil
nebula under darker mag 5.3 skies. This time the moon was up creating
some natural light pollution, so I tried to see the nebula again under
less than ideal conditions. The east portion (NGC 6992) was easier to see
compared to the west portion (NGC 6960) which goes right over a mag 4.2
guide star. I could just barely see this star with the naked eye.
Without a nebula filter I could not see the west portion at all,
despite knowing exactly what to look for and exactly where to look. With the
filter it was difficult but visible.
The east portion was visible without the filter. If you didn't know
what to look for, it would be difficult but doable. It mainly appears as a
large arc that goes from one side to the other in the eyepiece view.
With the filter, the east portion showed nicely, and was easier to find.
Either way, it's worth the hunt. Obviously, it did not show as well as
with darker skies.
If you have mag 4 skies, I recommend looking for the east portion. I
also recommend using a narrowband filter to improve the view.
The open cluster NGC 6940 is close to the mag 4.2 star also, and is
fairly easy to find with star hopping. (Need a star chart). This is a nice
open cluster that is as good or better than several Messier open
clusters (M26 and M103 for example), definitely a Messier class object. I
recommend this cluster for all small telescope users. I could see around
50 stars, most of them appearing as a uniform fairly dim brightness with
only a few brighter stars. What the stars lack in brightness they make
up for in numbers. The size of the cluster fills the view at 80x. The
lower power shows the overall cluster better compared to the
surroundings. The higher power shows the individual stars better. In 10x50
binoculars the cluster is also visible as a faint glow with a few stars. All
of this at mag 4.2 or so.

Telescope | 150mm f/8 TAL 2m Equatorially Mounted Newtonian |
Eyepiece | 25mm Plossl and a 15mm Kellner with a Lumicon U.H.C. filter occasionally threaded to each. |
Observing notes: |
After making a failed attempt to view the
East segment of the Veil Nebula (NGC 6992-5 or C33 in the Caldwell
catalogue) - which is possible under better conditions, I decided to view
the Blinking Nebula (NGC 6826 or C15). This planetary nebula was quite
difficult to find being situated in a rich area of the Milky Way. To find
this object I star hopped 6 degrees due North from delta Cygni to the
star 16 Cygni. NGC 6826 was located just to the East of this star. At
48x, NGC 6826 had a rather stellar appearance; the nebula was obvious at
80x. This nebula has the nickname of the "Blinking Nebula" due to the
disappearance of the nebula (and the appearance of the central 11th
magnitude star) when observed directly, when observed using averted vision
the nebula becomes more prominent and the central star less so. Thus in
the process of moving your eye around, the nebula is seen to blink.
However this may only be the case for some people, the nebula altered!
in brightness but did not blink when I observed it (irrespective of
whether the U.H.C. filter was threaded).
Next I observed another planetary nebula, NGC 7662 (or C22) in
Andromeda. The common name for this nebula is the “Blue Snowball” nebula. This
is another small but bright nebula, which is famed for its relatively
vivid colour. To find this nebula I first located omicron Andromedae by
moving approximately 14 degrees due North from beta Pegasi (the star
forming the top right hand corner of the square of Pegasus for Northern
hemisphere observers). The nebula is found about 5 degrees to the East
of omicron Andromedae.
At 48x the nebula looks stellar due to its small size, thus higher
powers are required to verify that the nebula has been located. At 80x the
nebula is rather reminiscent of the planet Uranus viewed at high power.
A small, blue circular patch was evident but no ring structure could be
discerned. The colour observed was unusually vivid for a planetary
nebula.
Both of these objects were quite difficult to locate, as I had never
observed either of them before. An atlas such as Sky Atlas 2000.0 is
essential to locate both nebulae and a filter such as a Lumicon U.H.C. may
prove useful in identifying these nebulae (the background stars fade
quite dramatically whilst the planetary nebula does not).

Date and time of Observation: | early Aug 2000 |
Observing Location: | backyard in Paris, Ontario, Canada |
Object Observed: | Veil Nebula, North America Nebula |
Viewing conditions: | transparency very good, seeing (steadiness) OK, moonless |
Telescope | 6" f/8 Newtonian, dob mount, Orion 1996 |
Eyepiece | 26mm Plossl, plus Meade "narrowband" filter |
Observing notes: |
Yes, these two can be seen in a 6"
telescope if the sky is dark enough. My backyard usually has a limiting
magnitude of 5, meaning that the faintest star in the Little Dipper is just
barely visible. On this night, a cold front had just passed and the
dryness made for a great night for this site. I could see several 5.3-ish
stars around the Little Dipper (I use a computer sky program that came
with the telescope to tell me the magnitudes). To add to the rareness,
none of my neighbours had their backyard house lights on!
To me the Veil Nebula is easier to find and see than the N.A. nebula,
and is more rewarding. The Veil is actually in several parts. I saw the
two brightest semicircle arcs.
Finding the Veil is relatively easy. It's hard to go into detail with
this text mode, but you start hopping off of the eastern-most star in
the Northern Cross (Cygnus the Swan). One of the Veil crescents is
sitting on top of a 4th (?) magnitude star not far from the Cross. The other
is halfway between the Northern Cross star and another 4th magnitude
star, not quite on a direct line between the two. If you get a good star
map, you'll see what I mean. I use Petersen's Guide, the same publisher
who does the bird guides. For guiding the telescope, I use Orion's
Easyfinder which puts up a single red dot. There is no magnification, but
the orientation is right side up just like your regular eyes, because it
is your regular eyes! Less confusing than a finder scope. As long as
you can see the 4th magnitude guide stars you can use the Easyfinder. (If
the light pollution doesn't let you see these guide stars naked eye,
you probably won't see the Veil anyway.)
Each arc of the Veil nebula looks like an irregular arc that goes
completely across my field of view (which is 1 degree). The arc is bent here
and there and has an irregular outline. I cannot see the filaments
described by others. This probably takes a larger scope or darker skies.
The narrowband filter makes a big difference. I can see the nebula
without the filter, but the nebula really jumps out with it. The brightness
of the nebula glow is not as much as M8, M42, or M17. But the shape and
size make up for it. Definitely a nice view, but may not make as big of
an impression with family members and non-astronomy friends.
I had a harder time finding the North America nebula, despite it being
close to Deneb, the bright star at the top of the Northern Cross. Again
I star hopped to some dimmer nearby 4th magnitude stars, but there are
a number of such stars and I was getting confused. Binoculars helped me
to sort things out. Also the N.A. nebula is very large, much bigger
than the eyepiece could show. The easiest part to see is the "Gulf of
Mexico". Once I found this then the rest could be figured out. The nebula
does not jump out like the other nebula, and was disappointing. The
grayish glow is much dimmer than M42, etc. Oh well, I now know where to
find it when I have darker skies and/or a bigger telescope. The filter is
almost a necessity.
Good luck to all.
Comment: Nice site!

Date and time of Observation: | August 19, 2000 9-11pm |
Observing Location: | outside of Ayr, Ontario, Canada |
Object Observed: | M22, M11, M26 |
Viewing conditions: | Limiting magnitude around 5.5, seeing fair-some tube thermals |
Telescope | 6" (150mm) f/8 Orion, dob mount, Newtonian reflector, 1996 |
Eyepiece | mostly 26mm Plossl (48x), also 6.4mm SuperPlossl (190x) |
Observing notes: |
M22 is my favorite globular cluster in my
6" scope. I can see 20-30 stars along perimeter of the cluster, most of
cluster is grayish blob. The resolved stars give the view a more 3-D
look. Disappointingly, I could not see more detail with the higher
magnitude eyepiece. This may have been hurt by there still being thermals in
my telescope, To see the thermals, first look at a bright star and then
unfocussing until you see concentric rings. Then the thermals show up
as blobs and distortions slowly moving around. (by the way, a good check
of collimation is if a dark circle is in the center of the unfocussed
star circle, if not you need to adjust hex bolts at the mirror, the dark
circle is caused by the secondary mirror). The thermals plus the low
altitude of M22 must hurt. The night was cold for this time of year (10C
= 50F) and was a little windy.
A 1996 review of my scope and two others in Sky and Telescope, quoted a
2-3 hour cool down time for the scope and I agree. The Celestron with
an open cell mirror mount design was apparently much better for
cooldown. I might try a battery cooling fan someday.
I have read that an 8" scope and higher is much better for globulars.
That the 6 inch is just at the threshold. I saw M13 in a 14" SCT at a
public observatory, which was spectacular with 100's of individual stars.
The open cluster M11 shows very nicely as others have described. At
48x, the sideways "V" shape is noticeable but is not obvious at 190x.
There is a single bright star in the cluster. The cluster appears resolved
at both 48x and 190x, but the higher power more easily separates the
individual stars. I did not count the stars, but 100 wouldn't surprise
me. The low power better shows the brightness of the cluster relative to
surroundings. In my opinion, M11 is the best overall open cluster,
bright stars, lots of stars, and easily distinguished from surroundings.
M26, another open cluster, is not far away from M11 but is harder to
find and recognize once you found it. I could only see at first about 5
stars with a faint surrounding glow, the glow being much dimmer than the
glow of a globular cluster. After looking at it for 5-10 minutes, I
could detect maybe 15 stars total. As usual averted vision helps. The
glow must be some dimmer unresolved stars. I have not read anything about
nebulosity in this cluster. Used 48x only. This is not the cluster to
show off to your friends, but the glow does add some mystery to me.
I also saw M8, M20, M21, M24, M18, M17, and M16 which make a nice
line-up north of Sagittarius, also M23 and M25 to the sides of this line.
Briefly, the nebulas M8, M20, M17, and M16 are all great. I used a Meade
narrowband nebula filter. The filter helps show more of the nebulas,
M16 (Eagle) is hard to see the nebula without the filter. M8 has the
great dark band. At 48x and the filter, the nebula pretty much fills the
field of view, about 1 degree. I could just make out the narrow dark
bands of M20 (Trifid), but if I didn't know what it looked like from
pictures, I think I would have seen the dark bands as just dark splotches. M17
is a great swan shape. The body of the swan is the brightest part. M24
is a huge scattered open cluster with lots of stars (actually I've read
it's not a cluster but just a Milky Way star cloud). M18 is a simple
open cluster between M24 and M17. More stars than M26 described above,
maybe 10-20, but no background glow of stars.
(By the way, I've seen all of these before and know how to find them
quickly. A beginner would not be expected to find this many at a time
without GOTO.)

Observing notes: |
Hercules
I started the night off by finding M13(mag 5.9), the well known globular cluster in Hercules. This was relatively
easy to find between Eta and Zeta which are two of the stars in the square of the constellation known as the 'keystone'.
The core of M13 was very bright when viewed through the 25mm eyepiece, on using the 9mm eyepiece
I was almost on the verge of resolving stars but not quite. I think individual stars resolved when I used averted vision
but it was hard to tell. Increasing the magnification further didn't make any difference.
However, this was my best view yet of M13.
Lyra
After finding M57(mag 9.4), the Ring Nebula for the first time the other night I decided to try again but this time without the help
of a star chart. It took a little searching but I eventually found it. As the moon wasn't around the nebula
appeared even brighter than a couple of nights ago with the smoke ring shape standing out well. The dark area in the middle
was also easily resolvable with the 9mm and 6.4mm eyepieces.
Scutum
My next target was M11(mag 5.8), an open cluster in Scutum. The constellation was low in the sky with M11 lurking in
the skyglow cast up by the lights on Nottingham 9 miles away.
I located the object by finding Beta Scutum, M11 was in the same field of view when using the 25mm eyepiece. The cluster
appeared to be quite compact and my first impression was that it resembled a globular cluster. On using the 9mm eyepiece
it became clear that this was an open cluster with many stars being resolved. I was astonished at how many stars were in this
cluster, I don't remember seeing any other cluster with as many (not yet anyway). This cluster
stood up well to higher
magnification. On using the 9mm eyepiece I lost the edges of the cluster but the central core was resolved in a myriad of stars.
I only wish that it was in a darker part of the sky.
Sagitta
This is a small but easy constellation to find with its distinctive arrow shape. I
centered the eyepiece on a small grouping
of stars slightly below and between Delta and Gamma Sagitta. With the 25mm eyepiece I could just pick out the globular cluster
M71(mag 8.3), it was quite a small object. Using higher magnification didn't resolve any stars but the globular could
clearly be seen.
Vulpecula
Heading North from Gamma Sagitta I went in search of M27(mag 7.3), The Dumbbell Nebula. This was a little trickier to find
and I had to rely on my star chart for this. It didn't take long to find. In the 25mm eyepiece it stood out well and I could
just make out the dumbbell shape. This object stood up well to high magnification and looked good in the 6.4mm eyepiece
filling about half the field of view. I wasn't able to discern any detail in the structure but nevertheless it was an
impressive sight.
Cygnus
As I was on a roll I decided to try and find M29(mag 6.6), an open cluster in Cygnus. I've seen this in binoculars as as small
grey fuzzy patch but have never tracked it down with my telescope. Well, tonight with the aid of my detailed star chart
I found it. I was a little disappointed and at first thought that I had missed it. M29 is a sparse open cluster with a few stars.
I wasn't sure where its boundaries began and I could count about 6 stars that were grouped quite close together.
I then found M39(mag 4.6), an open cluster in Cygnus. This was a little better than M29 as it had a few more stars on show
but it was still quite a large loose open cluster best viewed at low power. My best view was through the 25mm eyepiece.
Perseus
I'd never seen M34(mag 5.2), an open cluster in Perseus before. I found it easily in binoculars and it appeared quite bright.
I found Algol in my telescope and moved north until I could see the cluster in my viewfinder. The 25mm eyepiece showed the
cluster up well, it was a fairly loose grouping of stars and I estimated somewhere between 40 and 60 stars were visible.
Taurus
At this point I noticed two very bright stars just rising above the roof tops and realised that Saturn and Jupiter had returned.
I immediately centered on Saturn as this was slightly higher than Jupiter. I was astonished at the rich deep yellow colour Saturn looked.
The rings were tilted at a greater angle than when I last saw them. I was a little
disappointed that I couldn't focus properly
with high magnification and I put this down to Saturn being so low in the sky.
My view of Jupiter also suffered from atmospheric pollution with the south pole of the planet looking the same colour as Saturn!
and the north pole looking blue!. I waited a little while (took a peak at
the Pleiades M45) and things improved a bit to the point where I could see the main
equatorial cloud bands on Jupiter. What a great sight.
Unfortunately the clouds started to roll in so my night was over. I didn't really mind as I'd managed to find more
objects in one night than I'd ever done before with six of them being found for the first time. That topped off with the
arrival of Saturn and Jupiter made for a great night.

Eyepiece | 25mm Kelner, 9mm Kelner, 6.4mm Plossl |
Observing notes: |
I started the evening off with a quick look at Albeiro whilst my scope was cooling down. The pair was
easily split with the 9mm eyepiece with the orange and blue colours standing out beautifully against the
dark background.
I then moved onto Lyra to track down M57 (it's eluded me for so long) using the new star charts I've obtained.
I found it fairly quickly and was surprised at how small M57 was in size. Using the 25mm eyepiece I almost
missed it. I bumped the power up using the 9mm eyepiece and I could clearly see the doughnut ring
shape even though it has a magnitude of 9.4, as my eyes grew more
accustomed to the dark the image became a little easier to resolve. I tried to use the 6.4mm eyepiece but I could barely
make anything out (probably wasn't dark enough as the moon was rising). It was
fantastic to have finally tracked this object down at last. M31 in Andromeda
stood out well as a large elongated cloud with the edges gradually fading
away. This has never appeared any different to me when I've viewed it, I'm
not sure what difference I'd see from a dark site. The evening was finished off by viewing the Moon, I
used all the eyepieces eventually using the 2X Barlow with the 6.4mm
eyepiece. The detail along the terminator was incredible. There was one
dark region which had a mountain top illuminated giving the appearance
that the mountain peak was floating in space. I imagine that this might
have been a peak in the middle of a crater though I'm not really sure.

Eyepiece | 42 & 15mm kellner, 9 & 5mm orthoscopic |
Observing notes: |
Was looking forward to seeing this globular
for the first time. M13 was
quite easy to find in my 7x50 finder, being in the same field of view
as Eta. With 42 & 15mm (28x & 80x) the cluster was nothing more than a
misty patch and very disappointing. With the 9mm (133x) the image was
very faint and not helped by the bright moon but there was some
resolution at the edges, with about a dozen stars visible. The image was so
faint I could
only make out the individual stars by using 'averted vision'. To me,
the
cluster looked very 'ragged' with no obvious globular shape. Using the
5mm (240x) eyepiece made little difference.
Overall the cluster was less impressive than I expected but I'll try
again
on another night with a less intrusive moon, can't do much about the
street lights though.

Views of the two galaxies were very good with a dust lane evident in M82 and
hints of spiral arms on M81. I must note that the viewing site is very dark.
The given magnification is 82x and 1 degree of sky was seen. Both galaxies
were nicely framed in the eyepiece at this power. I could see hints of the
smaller third compainion galaxy (I forgot the NGC number) with this scope.
Comment: M81 & M82 are among my favorite galaxies to view.
Finding them may be difficult at first, but once
you have the hang of it, finding them is easy.

I was able to get a fuzzy, generally undetailed view of m101 which is traditionally a tough object.
M13 is easy and can be seen in the finder. It is incredible in a six
inch scope. The Great Cluster is an excellent name for it. Individual
stars can be resolved.. too many to count. M57, The Ring Nebula is
also a spectacular object in a six inch scope. At around 165x I was still
craving more magnification as subtle detail was visible. Gotta get
another eyepiece! All of these except m101 are easy targets with a 6"
scope and are great objects to see! As a relatively new observer, I was
not disappointed here!

Visual Nova Patrol
4:00 AM April 27/98 Calgary, Alberta CANADA
A rain shower has just passed through the area, the sky is crystal
clear. (no moonlight, no haze or ice crystals) I sit transfixed to my
eyepiece! Rotating my scope to the next familiar area of sky i observe a
star which i don't recall seeing before! I make a mental note to check
out my star charts when i go indoors. I proceed to my next area when
suddenly the silence is inturupted by the chirping of a lone bird. Soon
to be joined by a chorus of others. Although i enjoy listening to the
birds i also realize that the sun will soon be rising, putting an end to
my observing session.
I have just described a typical session of patrolling the milky
way for nova, which is my primary astronomical pursuit. A low tech, low
cost, fun, definitly challenging and IMO rewarding endevour. Dark skies
not mandatory, spend your time observing rather than travelling.
ADDENDUM:
For those whom are wondering why I am using a scope to do my observing
rather than binoculars which is really all that is required, there are
really two reasons. First of all i am forced to do most of my observing
from the city. Do have a homebuild observatory in the backyard, keeps
me shielded from the wind and streetlights. The other reason is that i
am visually impaired. Have a inherited condition known as atrophy of the
optic nerve. If you wish to learn more about nova patrolling the AAVSO
(American Association of Variable Stars has a committee devoted to nova
patrol. I would also recommnd the book New Horizons in Amateur
Astronomy By Grant Fjermedal which has a chapter devoted to nova patrol.

Observing notes: |
The triple star zeta Cancri was occulted by a 90% illuminated moon
early
Saturday morning on 2/27/99 UT. I had planned to observe the event from
the
Astronomical Society of Harrisburg's Naylor Observatory but after doing
some observing from my balcony with my new ATM 6" f/10 Dobsonian
mounted
Newtonian I decided to watch the event from my residence instead. That
way
I wouldn't have to tape David Letterman and I could stay relatively
warm
to boot.
My astronomical activities were not limited to the hours after
nightfall,
however. At 15:28 UT Friday morning I checked for solar activity with
my
114mm f/7.9 C4.5 and noticed three small sunspots and one very small
one
at 53x, under poor seeing.
After sunset I used my Pentax K-1000 to take a few shots of Venus and
Jupiter as they blazed brilliantly in the western sky less than 5
degrees
apart from one another. I had set up my 6" Dob to begin cooling
beforehand
and after returning from the nearby park where I photographed the two
planets I had a quick look at Venus before moving on to Saturn. This
was
really the first time I had used the 6" under good conditions (adequate
thermal equilibration, relatively good seeing and transparency, 59%
relative humidity, 36 degrees Fahrenheit, 30.10" barometric pressure)
since I had
purchased it from a fellow member of the Delaware Valley Amateur
Astronomers and I was quite impressed with what I saw.
I used magnifications of 80 (19mm Tele Vue Panoptic), 90 (17mm Tele Vue
Ploessl), 127 (12mm Tele Vue Nagler), and 227x (6.7mm Meade UWA). With
a
focal length of 1524mm and a baffled tube this scope produced
surprisingly
good views of the ringed planet. Seeing the Cassini Division was not a
problem. Because of the awkwardly long optical tube this is not the
easiest
telescope to use, however.
Throughout the night I would observe for short periods while watching
the
movie "Seven" (for the second time) and other television programs (the
idiot's way to observe, right?). Despite the strong moonlight and
excessive
local lighting I logged a number of deep-sky objects: M42, NGC 1981,
iota
Orionis, Rigel, M41, M50, M45, sigma Orionis, Struve 761, delta
Orionis,
h3945, NGC 2362, W Orionis, Struve 817, beta Monocerotis, Struve 939,
NGC 2244, M47, and M36. (My vistas were limited by the balcony roof,
trees,
and the side of the building.) My 30mm Celestron Ultima (51x), 19mm
Panoptic, and 6.7mm UWA saw action in this DSO campaign.
As the moon neared zeta Cancri I spent some time on the area
surrounding
the terminator. The western crater wall of Aristarchus was nicely lit
and
I had a fine view of Gassendi. I also inspected Sinus Iridium,
Bullialdus,
Schiller, Tycho, Clavius, Copernicus, Reinhold, Kepler, and the rays
emanating from Proclus and other craters. The magnifications used were
80,
90, 160 (2x Ultima Barlow lens), 227, and 455x (2x Ultima Barlow lens).
I
believe I was able to resolve zeta Cancri as a triple at 455x.
After the occultation occurred I swung my scope to the south and viewed
Mars at 90 and 227x using a Wratten 21 filter. For the first time
during
this Martian apparition I was able to discern a surface feature, which
may
have been Acidalia Planitia.
I also looked at delta Corvi at 80x, M44 at 59x (26mm Tele Vue
Ploessl),
and Castor at 227x.
Zeta reappeared sometime around 07:25 UT and after having a final look
at
Mars I called it a night, the Night of the Long Dob.

Date and time of Observation: | 6th May 2000 |
Constellation: | Ursa Major |
Viewing conditions: | Good |
Telescope | 6" Orion Skyview Deluxe |
Eyepiece | 25mm 9mm |
Observing notes: |
The Whirlpool Galaxy is an easy target with a 6" scope. Just to the right of the end of the tail in Ursa Major are two stars that point almost directly to it. Follow these and you will see an "L" shape of three stars in your finder. Put in a 25mm eyepice and you can't miss this one. The two cores are clear and separate. On a very good night with the eyepice bumped to a 9mm some detail of the spiral shape comes out. This a great galaxy to get started on and is easy to know you are looking at the right thing because of the small companion whose core is so readily visible. Good Luck! |

Date and time of Observation: | 6 April 2000 - 22:00 GMT |
Constellation: | Leo |
Viewing conditions: | Clear skies, naked eye visibility around Mag. 5. |
Telescope | 150mm Orion Europa Reflector |
Eyepiece | 25mm kelner |
Observing notes: |
Located two galaxies M65 (mag 9.3) and M66 (mag 8.9). Hopped from J to 73 (by moving south halfway between J and i ) and centred on a small star to the east of 73 (they're in the same field of view with a 25mm eyepiece). Both galaxies are very faint and would be easily overlooked if you didn't know they were there! They're slightly above the small star centered in the eyepiece. M65 was elongated in shape and quite thin. M66 was larger in size and not quite as elongated as M65. There appeared to be a band diagonally through the galaxy that wasn't visible giving the impression that the galaxy was split in two. There were also two small stars in the same line of sight that appeared to be sitting on top of the galaxy. |
