Located object by star hopping from eta Sagitta approximately 3 degrees north. Object appeared about 5 mins arc diameter. Although very dim through a Department Store Telescope, I was amazed I could see it at all. Averted vision helped tremendously to see the hour glass shape of the Dumbell. (At least, that's how it appeared to me) This was my first planetary nebula I have every seen with this scope, and I have to say, I got goose bumps. Can't wait to view it through a bigger scope someday. |

Observing notes: |
Last week, I finally ordered an 8" dob from Discovery Telescopes.
Trying to break the Astronomer's Curse, I ordered it on a day when it
was pouring down rain. Hopefully, this would mean that the telescope
would arrive on a clear day.
While I'm still about a week away from receiving my telescope, today
was one of those days that I wish I had it. The sky was cloudless all
day today, and the temperature reached the upper 50s. Perfect weather
to give a person Spring Fever. I didn't have many plans tonight, so I
hoped the weather would hold until this evening.
Much to my amazement, it did. After supper, I grabbed my gear and
headed out to the backyard. Even better news: my neighbor's porch
light was off. I didn't really have a set observing plan tonight, so I
thought I'd just look at whatever caught my fancy. After
unsuccessfully trying for a few galaxies and nebulae, I decided to
concentrate on open clusters.
M41 [Canis Major] - 7:50pm CST (Open Cluster)
At 56x, several stars were visible. Overall, the shape appeared oval
and was pretty loose. There were about a dozen fairly bright stars,
with even more fainter ones visible throughout the cluster.
Dropping the power down to 35x, you can still easily tell that this is
an open cluster. There are several bright stars visible, along with
some dimmer ones. Throughout the cluster, there is a mottling or
slightly nebulous appearance. By moving the telescope slightly back
and forth, the cluster is even more obvious than when staring directly
at it.
Through binoculars, about six bright stars are visible, with a lot of
mottling or fuzziness surrounding them, forming a loosely circular
shape.
M48 [Hydra] - 8:00pm CST (Open Cluster)
This is a large open cluster. At 35x, it appears roughly circular,
with a triangle or wedge of compacting near the center. In the rest of
the cluster, the bright and faint stars are fairly evenly distributed.
Bumping up the magnification to 56x, the cluster takes up the entire
field of view. In the center is a crooked string of stars. With direct
vision, this line consists of about six stars, but with averted
vision, several more are detected.
This cluster appears to have the potential to be a lot prettier, if
more stars were visible. The fact that it is fairly low in the sky and
I have a lot of light pollution in the Southern portion of my sky
didn't help matters, I'm sure.
At this point, the neighbor turned her porch light on. So I decided to
devote the rest of the evening to binocular viewing. I was wanting to
bag a few more open clusters with them anyway. I recently purchased a
lawn chair that has an adjustable back, and it makes it much easier to
lay back and enjoy the view through binos. Even without a tripod, I
could rest my arms against the chair and achieve fairly steady views.
M47 [Puppis] - 8:15pm CST (Open Cluster)
This is a fairly loose cluster, and a pretty easy target for
binoculars. Several bright stars are visible.
M46 [Puppis] - 8:20pm CST (Open Cluster)
In the same field of view as M47, this cluster looks like a faint
cloud. I could barely detect that anything was there.
M35 [Gemini] - 8:20pm CST (Open Cluster)
Even in binoculars, this is a nice open cluster. It appears as a
definite fuzzy patch with a few stars resolved. Using averted vision,
about six stars can be detected.
M44 (Beehive) [Cancer] - 8:23pm CST (Open Cluster)
A couple of dozen bright stars are visible. A few of the "beehive"
stars are resolved into double stars, and another bright double is
visible near the outer edge of the cluster.
M45 (Pleiades) [Taurus] - 8:26pm CST (Open Cluster)
Stunning! The cluster fits nicely into the field of view. The seven
brightest stars are readily visible and the cluster is sprinkled with
many fainter stars. Even at its relative low altitude, it is a
magnificent sight.
M36, M37, M38 [Auriga] - 8:35pm CST (Open Clusters)
All three of these clusters lie pretty much in a straight line with
each other. Through binoculars, all three objects are just fuzzy
smudges against the night sky. M37 appears to be the largest of the
three clusters, and M36 appears to be about the brightest and
smallest. The faintest one is M38, but luckily, there are some bright
stars in its general vicinity.
By this time, the temperature was really starting to drop quickly, and
I was having a hard time keeping my binoculars from dewing up. So I
called it an evening. While I'm hoping for great views out of my new
telescope, I hope I don't completely dismiss my small refractor. I've
spent hundreds of hours with it, and want to spend hundreds of hours
more.

Object Observed: | Moon and planets |
Viewing conditions: | Clear, light pollution |
Telescope | Meade DS60 60mm Refractor |
Eyepiece | 25mm and 9mm stock |
Observing notes: |
My first night out since I was a little kid
with a telescope. Wasn't really sure what I could see, if anything at
all, with a cheap 60mm telescope in badly light polluted skies with a
half moon high in the sky. The moon sure is spectacular at 28x. I was
definitely amazed at the resolution and detail. 9mm was great but the
field of view was annoyingly too small. The shadows near edge of the half
moon were breathtaking. I then headed off to the Orion nebula but could
see only the slightest hint of a nebula which merely seemed as a slight
glare around two visible stars, testament to the horrible light
pollution in my area, I assume. Off to Saturn. I try to get it perfectly
focused. hmm disk seems stretched in the vertical, oh those are the rings! At
9mm on this scope I have 78x zoom, and Saturn is soooo tiny! Luckily
the rings are at a great tilt, and I can just barely discern a break
between the planet and its rings. Cool! But really too small to enjoy!
much. I edge the scope upward to Jupiter. The moons seem so far away
from the planet. Again the disk is very small, but cloud bands are
visible. Cool! A 4th moon is visible just outside of Jupiter's disk.
Comment: If anything I whet my appetite for higher magnification and
darker skies! I'm thinking 120-140x would be nice, if the scope can do
it. |

Eyepiece | 22mm Kellner, 12.5mm Kellner, 10mm Plossl, 6mm Ortho |
Observing notes: |
Last night, the sky was clear and transparent, but I was too tired to drag my telescope outside. I hate to miss opportunities such as this, but sometimes it just can't be helped. Luckily, my skies were blessed with two clear nights in a row. While not quite as many stars were visible as the previous night, I didn't want to push my luck, and grabbed my gear.
Sigma Ori [Orion] - 10:30pm CST
Despite trying several different magnifications and eyepiece
combinations, I was unable to make out the C component. Perhaps it is beyond the
reach of my small telescope.
Struve 761 [Orion] - 10:40pm CST
M44 (Beehive Cluster) [Cancer] - 10:50pm CST
One of the points of this pentagon-shaped asterism is a double star and
two of the other points are triple stars. One of these triples,
comprising the "roof" of the house shape, is a nearly equilateral triangle.
All of the stars appeared to be white in color. Pushing up the
magnification revealed even more stars, but the cluster would no longer fit
within the field of view and lost some of its beauty.
Gamma Leo [Leo] - 11:00pm CST
While the two stars are similar in color, those colors are so intense
that it still makes for a pretty sight. One of the great charms of this
double is that it is like getting a present. 40 Leo is a beautiful bow,
and as you increase the magnification and peel away the wrappings, the
double gift is revealed.
By this time, the temperature was starting to drop quickly, and the
finger I had broken a few weeks ago was starting to throb in pain with the
cold weather. I took a quick peek at Jupiter, but didn't notice any
real detail that I hadn't logged before. So I packed it in for the night.

Object Observed: | M31 |
Viewing conditions: | Unusually clear but light -polluted |
Telescope | 60 mm Bushnell Refractor |
Eyepiece | 16mm Plossl |
Observing notes: |
I finally found M31 four nights ago with my
8X42 binoculars. Have been casually observing moon, planets, etc. for
around 2 years. Seeing conditions locally are atrocious in summer
months due to smog and light pollution. After sighting Andromeda, I had
another sighting, a long slender "chevron-shaped" UFO. It was a very large
dark gray V-shaped with a few tiny white lights in the center of each
"wing" apparently at a very high altitude. I watched it for about five
seconds from overhead to half way to the western horizon where it
suddenly disappeared. I have been interested in UFO's most of my 62 years
but this is the first time I have seen anything hard to explain away.
After that I got my department store refractor out and was able to capture
M31 again. In the 16 mm eyepiece, M31 actually looked smaller than in
the binoculars probably because of light loss. I was more excited about
M31 than the "UFO". It was probably an experimental US craft ( perhaps
made with the help of some little gray folks).
Comment: Dim objects in a small refractor require very good seeing
conditions. Jumping from star charts to binocular view to much narrower
telescope field of view is confusing and much dimmer images take some
getting used to. We are lucky to have access to pro telescope images on
the internet but nothing beats seeing things for yourself.

Observing Location: | Iola, KS |
Object Observed: | Various |
Viewing conditions: | Great |
Telescope | 60mm Focal refractor |
Eyepiece | 22mm Homemade Kellner, 10mm Plossl |
Observing notes: |
M38
This is a pretty faint (at least, for my telescope) open cluster. At 32x, M38 appears as a faint, mottled smudge.
Increasing magnification to 70x, several individual stars can be resolved, but they are about at the limiting
magnitude for the telescope. Even then, averted vision had to be used to resolve them.
However, by using averted vision, about 20-30 stars could be detected at 70x. With this eyepiece, the cluster
was framed nicely within the field of view. The cluster is irregular in shape; roughly circular with several
extended appendages protruding at odd angles.
M35
This is a fairly large open cluster, taking up most of the field of view at 70x. There are dozens of stars
visible. Eight or nine of these are fairly bright, with a multitude of fainter ones.
The overall shape reminded me of a delta wing or boomerang. I also detected a few apparent doubles within the
cluster.
Zeta Orionis
(Multiple Star system)
This is a fairly impressive star system, located right below the belt of Orion. One of the stars is fairly bright,
and there are four other stars in the system that are about a magnitude fainter. One of those four stars forms a
pair with the bright star, and two of the others form a second pair, slightly wider, and the fourth star is on the
other side of the bright star. Together, these five stars form a long, narrow V shape. There is also a fifth star
of similar magnitude in the field of view, but it is about twice as far away as the other stars, so I'm not sure
if it is actually part of the system or not.
By bumping up the magnification to 70x, I detected another companion star around the brightest star. This
companion is another magnitude fainter than the other stars, and is pretty close to the primary. All of
these stars appeared white.
M42
(Great Orion Nebula)
What more can I say? This is simply a magnificent nebula, and I nearly always stop and take a look at it when
it's in the sky. At low power, the nebula shows up beautifully, with the dark "fish mouth" band separating M42
from nearby M43.
The sky was pretty clear tonight, so I decided to kick the magnification up. I threw my barlow lens in front of
my star diagonal and 10mm eyepiece to achieve about 210x. The combination of good seeing and my new Plossl
eyepiece allowed me to actually see all four of the main stars in the Trapezium for the first time. Previous
attempts only allowed me to see three of the stars.
Kicking the magnification back down to 70x, only three stars were visible in the Trapezium. Putting the barlow
in front of my diagonal and 22mm eyepiece yielded about 95x, and the fourth star could sometimes be detected
with averted vision, but not consistently.
NGC-2169
("37" Cluster)
I've seen pictures of this cluster in books, and it does indeed resemble the number 37 in those pictures.
However, in my telescope, with the star diagonal attached and not being able to detect most of the fainter
stars in the cluster, the shape appears much different.
I could detect two distinct parts of the cluster at 70x. In the "7" half of the cluster, I could make out
two stars with direct vision and three stars with averted vision. In the "3" half of the cluster, I could
detect four or five stars, with a lot of nebulosity interspersed throughout. The brightest star of the cluster
was also in this half.
Overall, this cluster isn't very impressive at this aperture, but at least it's detectable and recognizable as
an open cluster.
Mel25
(Hyades)
With my 22mm eyepiece, I can easily fit all six of the main central stars in my field of view. These stars are
grouped into three bright pairs of stars and is located on one of the horns of The Bull. The pairs of stars seem
to be facing each other, pointing to a central location.

Date and time of Observation: | 11/19/2000 - 10:18pm CST |
Observing Location: | Iola, KS |
Object Observed: | M36 + M37 |
Viewing conditions: | Great |
Telescope | 60mm Focal refractor |
Eyepiece | 22mm Homemade Kellner, 10mm Plossl |
Observing notes: |
At 32x, M36 appears as a fairly
circular smudge of light. About a dozen stars could be resolved, with
hints of nebulosity between.
At 70x, a lot of the nebulosity is resolved into fainter stars. There
really isn't much of a discernable pattern to the stars. If anything,
this open cluster reminds me of a loose globular, with its round shape
and being denser toward the center.
M37 is much fainter than M36, and appears
to be much more condensed. At 32x, it appears as a mottled gray circle,
with just a few stars being resolved.
At 70x, the cluster becomes faint enough that it almost disappears.
However, several individual stars can faintly be made out. These stars are
obviously packed tightly together. This cluster comes even closer than
M36 to being a globular. With a little more aperture to brighten the
cluster, this would probably be fairly spectacular.

Object Observed: | Eta Cassiopeia (double star) |
Viewing conditions: | Fair (Clear, but some haziness) |
Telescope | 60mm Focal refractor |
Eyepiece | 22mm Homemade Kellner, 10mm Plossl |
Observing notes: |
This one presented a bit of a challenge in
my small telescope. The second component of this star system is about
four magnitudes fainter. Based on the apparent orbit of the secondary
star (according to my Burnham's Celestial Handbook), these two stars are
almost at maximum separation right now. If that is the case, then I
would probably never be able to have detected the second member when they
were at their minimum separation.
The bright primary appeared slightly off-white (perhaps even gray),
whereas the dim companion was a medium blue. I was able to barely catch a
hint of the secondary star at 32x, so I switched to 70x (Plossl
eyepiece) to verify that the second star was indeed there. After confirming, I
went back to 32x and the secondary appeared a bit more obvious (since I
knew right where to look).
This pair does have a rather nice color contrast, and could easily be
added to the "favorites" list of observers fortunate enough to own
telescopes with a little more aperture.

Viewing conditions: | Fair (Clear, but some haziness) |
Telescope | 60mm Focal refractor |
Eyepiece | 22mm Homemade Kellner, 10mm Plossl |
Observing notes: |
This is a really nice and wide multiple
star system, viewable with the naked eye as a small hazy patch. I had
looked at this system before, but didn't have a star chart handy to tell me
exactly what it was, so didn't log it. I rectified that problem
tonight.
At 32x, a triangular formation of stars is readily apparent, with the
two end stars (Psi1 and Psi3) each showing a fairly close binary
component.
When viewing at 70x through my Plossl eyepiece, Psi1 actually becomes
three stars, in a roughly equilateral triangle. The third component is a
little fainter than the other two. y1 would normally be a worthy target
in its own right, but when combined with Psi2 and especially Psi3 in
the same field of view, this becomes a good object to show off at star
parties.

Light pollution from my garden is so intense that in my Vixen 102mm achromat only the nucleus of M31 in Andromeda is visible, making it look like a larger version of M32. If your sky is polluted, too, don't despair. Out in the countryside the little spotting scope (erect image) shows faintly but unmistakably the great oval stretching across half of the field of view - more confirmation for me that limited equipment plus a good sky makes a more potent combination than lavish equipment stuck in a light-polluted location. M39 in Cygnus was outstanding, too. |

Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
At 32x, it appears as 5-6 stars with a
little bit of nebulosity. At 56x, six stars are clearly visible, forming
sort of a butterfly, with three stars making each wing. At 116x, a few
more members are visible, one more on one of the two wings, another star
near the front end of the "butterfly", and two more off to the side
which may or may not be part of the cluster.
This isn't much of a cluster for small telescopes, but the unique shape
gives it a little bit of character. Please note that this cluster
shouldn't be confused with the Butterfly Cluster (M6), which is in the
constellation of Scorpius.

Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
Now that Saturn was fairly high in the sky,
I decided to give it a try. I decided to use the same magnification
that I used on Jupiter (112x). The rings were at a pretty good angle, so
that the near side of the rings barely obscured the bottom of Saturn,
and the planet barely obscured the far side of the rings. At low power,
it comes close to resembling the CBS logo.
Right above Saturn was the faint Titan, Saturn's most easily-visible
moon. Since it was above the planet, it must have been passing behind the
planet, but was visible due to Saturn's large tilt.
On Saturn itself, there was a little bit of evidence of banding, as
some latitudes appeared more shadowy than others. The Cassini Division was
just barely detectable at the sections of rings that were farthest away
from the planet.

Viewing conditions: | Great, except for waxing gibbous Moon |
Telescope | 60mm Focus refractor |
Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
By this time, Jupiter was just starting to
clear the trees. In order to get a better view, I retracted the tripod
legs of my telescope and set it on top of the trunk of my car. This had
the added advantage of allowing me to remove my star diagonal, thereby
reducing the number of surfaces that Jupiter's light had to travel to
reach my eyes.
At 56x, I could clearly make out the two main bands of Jupiter. The one
closest to the equator was really prominent, but both had a medium
brown color. Three of Jupiter's moons were lined up almost equidistant
apart on one side of the planet and the other Galilean moon was alone on
the other side of Jupiter.
With my 6mm Ortho lens (producing 116x), Jupiter appeared larger, and
was still well-focused. The two bands, although a little fainter, still
stood out on the gas giant. At this magnification, The 80A Blue filter
seems to perform the best (of the four filters I have), as it blocks
out the glare, but still allows most of the banding details to shine
through. At this magnification, the two main bands appear thicker, but no
more bands are visible.
Despite being so low in the sky, this is probably the best view of
Jupiter I've had in a long time. The transparency and seeing must have been
incredible. What I would've given for a true dark-sky site with no
Moon...
With this kind of sky conditions, I was able to push the magnification
up on the planets. I found that my best view of Jupiter was with my
12.5mm Kellner eyepiece stacked on top of a 2x barlow (unfiltered),
resulting in 112x. Although my 6mm Ortho produces 116x, the field of view is
enough smaller that I spend more time moving my telescope to keep up
with the planet than I do observing it. I don't think the Great Red Spot
was on the near side of the planet at the time, or I'm pretty sure I
would've been able to see it.
After Jupiter had risen a little more in the sky (about 30 degrees
above the horizon), I took another peek at it. I was now able to combine my
star diagonal with the 12.5mm Ortho and barlow lens. By placing the
barlow ahead of the diagonal, I could achieve an approximate magnification
of 168x. The two main bands showed a variation of thickness and color
along their lengths. Occasionally, hints of a third and fourth band
would show through, but would quickly disappear again.
Trying to push the magnification any higher resulted in a fairly blurry
and wavy image, but the fact that I even considered pushing it up that
high is a testament to how good the seeing was tonight.

Even though they were just above the
treetops, I couldn't resist the urge to view one of the finest deep sky
sights in the sky. With the naked eye, I could easily make out its six
brightest members. With the low-power eyepiece, I could resolve dozens of
stars (probably between 50-100), of varying magnitudes. They form
interesting pairs and chains of stars.
The early-morning eastern sky is really magnificent right now, with
Jupiter and Saturn dancing between the Pleiades, the Hyades, and
Aldebaran.

Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
The Moon was in Capricornus tonight, so
nearby Aquarius was kind of washed out with glare. Nevertheless, I thought
I'd try to bag M2 tonight as well. To find it, I starhopped from about
1/3 the distance from b Aqr to e Peg (the nose of the flying horse).
At low power, this is a pretty dim globular. Stepping up the resolution
didn't reveal any real detail, but I was able to see a couple of nearby
dim stars in the same field of view.
At high power, its definitely larger and globular, but I was still
unable to make out any individual stars. The contrast was enough at high
power, however, that it is probably a pretty decent cluster. I've put it
on my list of things to observe again when the Moon isn't interfering.

Object Observed: | M15 (Globular cluster in Pegasus) |
Viewing conditions: | Great, except for waxing gibbous Moon |
Telescope | 60mm Focus refractor |
Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
This cluster is nicely nestled along the
borders of a triangle formed by three fairly bright stars in the same
field of view, making it pretty easy to find. At low power, it appears to
be smaller and brighter than M13, but without much structure or
resolution.
At 56x, its definitely round in shape. The center appears almost
stellar, and then gently fades to nothing at the edges. This cluster is
similar in size to M92, but is brighter and more impressive.
At 116x, the cluster is larger and starts to appear a little mottled,
but no real resolution of stars is evident, even at the edges.

Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
This is the first time I had ever viewed
this planetary nebula with my telescope. At low power, it is a dim smudge
against the background stars. The shape couldn't really be discerned,
except that it obviously wasn't spherical.
At 56x, it was larger and dimmer, but I still couldn't make out the
dumbbell shape. It seems to be a lot larger in size than M57 (the famous
Ring Nebula). My overall impression with this nebula was that it was
even better than M57 for low-power viewing. The lack of a lot of bright
stars in the immediate vicinity of M27 makes it stand out a little more,
I think.

Telescope | 60mm Focus refractor |
Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
I remembered that I hadn't yet logged M52,
so thought I'd look it up. At low power (32x), I could detect one or
two stars within a smudge of nebulosity. At this small level of
magnification, its easy to see how Charles Messier may have at first mistaken
this object for a comet.
Increasing the magnification to 56x revealed a few more stars (maybe 5
or 6), and most of the nebulosity had disappeared. With my 60mm
telescope, this is overall a pretty unimpressive little cluster, with few
stars or structure visible.

This is another one of my favorite deep sky objects. These clusters appear best at low powers, when both can be seen in the same field of view. They appear as two loose balls of stars. One of the clusters appears slightly larger, and the other cluster appears slightly brighter. At higher powers, a lot more stars are visible in both clusters, but only a single cluster will appear in the field of view, which diminishes a lot of its uniqueness and beauty. |

Eyepiece | 20mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
The sky finally got dark enough to see the
necessary guide stars that would allow me to pinpoint Comet LINEAR's
position. It was right where the Skyhound web site said it would be.
Tonight was a good night to view it, since a fairly bright star was in the
same field of view as the comet. This allowed me to focus on the star,
then view the comet.
The comet itself looked like a bright patch of nebulosity, with a faint
fantail sweeping up toward the zenith. If the night was darker, I'm
sure the comet would look better, but by that time, it would be too close
to the horizon. At medium magnification (56x), the core was readily
visible, but a lot of the tail structure was lost, due to its faintness
and the narrower field of view.
Due to the rarity of the event, I invited my family to come and take a
look. My mother and my younger brother both took a look at it, but
didn't see much more than a fuzzy star.

By moving up to medium power, more stars are visible, but to me, the butterfly shape isn't at all apparent. This is a pretty loose and widespread cluster. |

Eyepiece | 22mm Homemade Kellner, 12.5mm Kellner, 6mm Ortho |
Observing notes: |
This is a nice open cluster. With lower
power (30-35x), the cluster fits nicely within the field of view, with a
nice border of background stars all around it. I was able to count about
30 members with direct vision, with more fainter members detected as I
looked longer. The shape of the cluster is pretty irregular and hard to
describe.
At the heart of the cluster, there appears to be a double star. At 56x,
the double star is definitely there and even more cluster members are
visible. At higher powers, this cluster sort of reminds me of a
miniature Beehive cluster (M44), except not as rich.

Pretty impressive globular. It is definitely in the same league as M13 in Hercules.

Observing notes: |
M12 is a really faint globular, and is
almost impossible for me to see with direct vision. I was only able to spot
it for certain by moving my telescope around slightly and catching a
bright spot out of the corner of my eye. At 56x, M12 nearly disappears
completely.
M10 seems to be slightly brighter than M12, but I am unable to resolve
any stars. At 56x, M10 shows up pretty nicely, but is still unresolved.
The increased contrast of the higher magnification has made the cluster
really jump out at me.
The constellation Ophiuchus is in a fairly light-polluted portion of
the sky for me, so its not too surprising that I had a hard time seeing
M12. Under a darker sky, I'm sure it would show up much better.

The center section of the cluster has about 11 of the brighter stars, arranged in an unique shape that is difficult to describe. Overall, this is a nice cluster, and at medium to high powers, becomes pretty rich. |

About a dozen members are visible at low power. It appeared to have nebulosity toward the middle of the cluster. At 56x, most of the nebulosity was resolved into individual stars, about 30 members being visible. At this medium power, the cluster encompasses the entire field of view. Jumping up to 117x resolves many other members, but because only the center portion of the cluster is visible, it loses a lot of it's shape. With the left-right reversal through my eyepiece, the cluster reminds me of the main stars in the constellation Orion, with the "belt" stars being about twice as far apart proportionally as they are in the actual constellation. |

Observing notes: |
At low power (32x), a small, obvious nebular patch is visible below the star g Scu. Bumping the magnification up to 56x reveals a little more detail. In fact, it vaguely resembles a chevron or boomerang, with the point of the chevron pointing almost directly toward g Scu. Even though the higher magnification lessens the amount of light coming in, the increased contrast from the background sky makes it even more obvious than at low powers. At 117x, the nebula became too dim to see. |

Viewing conditions: | 100% when not obscured by passing cloud; partly cloudy |
Telescope | 60mm Refractor |
Eyepiece | 20mm |
Observing notes: |
I checked my email that day and received a
report from the Sky & Telescope newsletter telling about the recent high
number of sunspots due to the Sun's Solar Maxum Cycle. Since I had only
been keeping up with the solar activity through online data, I thought
that I would go out and see it myself. I set up my refractor with an
attachment made specifically for solar observation which allowed the
image of the sun to be projected onto a metal plate situated about 10
inches from the eyepiece. I took a sketching pad, as was the habit of all of
my solar observing, and wondered how many groups of sunspots I would
draw.
After aligning the tube's shadow with the direction of the
sunlight, I removed the cover from the end of the telescope and let the sun's
image shine through. A few seconds of adjusting and there it was: a
smooth yellowish ball silhouetted in black with small black specks here and
there across the middle regions from east to west. I counted six
groups altogether and two groups, in particular, that were pretty
heavily populated. It was not the most that I had seen at one time (I
counted eight groups on Halloween day last year and observed at least seven
groups daily throughout that same month), but I figured that the bigger
scopes could see a lot more small groups that I could see. I like it
when the sunspot groups are big enough to see the feathery-looking
billows around them. creating a surrounding outline.
Comment: As may have noticed, I limit my solar observing time to just a
few minutes. I learned the hard way that the plastic that cradles the
lense can melt after too much observation. I almost melted a 12mm lense
in about 40 seconds of exposure time. It was saved only by my immediate
averting it from the sunlight when I noticed a burning smell...
Needless to say, I never use my higher power lenses, such as 4mm, to observe
the sun.

Magnificent looking, as usual. I don't have
a long enough eyepiece to be able to get the entire coathanger into a

sideways.
Lying west of Sagitta, Cr399 is pretty easy to spot with the naked eye.

This is the first time I've ever looked at

few fairly bright stars, kind of reminiscent of the Great Orion Nebula
(M42). Also similar to M42, there appears to be two nebula split by a
wide dark lane. There are probably fewer stars in this region of the
cluster.
At higher powers, this cluster became too faint to make out any detail

isn't visible at all. After going inside, I confirmed the position angle
for e2 Lyrae to confirm that I was seeing what I thought I was seeing.
It's interesting to note that I was only able to separate the closer of
the two pairs. I attribute this to the fact that the two components of
e2
Lyrae are closer to each other in visual magnitude.
This is the first time I've been able to detect an elongation of either
component, so my observing skills seem to be improving a little.

Kappa Boötes After viewing this binary for the first time the other night, I marked it as a favorite. While not as impressive as Albireo (Beta Cygni) or Gamma Leonis, it has a beauty all its own. I think the companion star is the first one I've viewed in my telescope that has a distinctly brownish tinge to it. At 35x, I can just barely make out the companion star through the glare of the primary. At higher powers, the companion becomes more obvious, but dims significantly.

a special place in my heart.
The yellow-gold and bright blue pair makes for an exceptional color
contrast. While the stars look nice at about any resolution, low powers
seem best. The wide double is easily split and even in this rich region
of stars and nebulae, they have no problem standing out from the crowd.

Observing notes: |
By around 11:30pm, Lyra had finally cleared
the treetops, and made for a tempting target. Last summer, I had tried
unsuccessfully several times to make out M57. Because of its unique
location, I know I had the object in my field of view, but just couldn't
see it. I decided that I didn't have anything more pressing to do
tonight, so I'd take another crack at it.
Even though Lyra was still fairly low in the sky, I was able to
positively ID it tonight for the first time in my telescope! It was a lot
fainter than I had imagined it to be, based on observation reports by
others. In fact, I had to point the scope back and forth between a nearby
star several times just to verify that it wasn't simply an out-of-focus
star.
Since the other stars seemed to be in focus, it must be M57. Absolutely
no detail was available at any magnification. At 28x, M57 was
indistinguishable. At 56x, it appeared as a dim out-of-focus star. At 116x, it
was just barely detectable due to the dimness.

At this point, M13 was just starting to climb above the glow from the highway streetlights to the East. Not really expecting much, I decided to give it a try, anyway. After all, its a hard object to pass up. I tried several different magnifications on it, including 35x, 56x, and 116x, but the best view was at 35x. It was definitely nebular in appearance, reminding me of Charles Messier's description (bright nebula with no stars visible) of the object. Knowing that it was a globular cluster, I felt like I was right on the verge of being able to resolve a few stars, but it could have been my overanxious imagination. |

Tonight's observing session was mainly to
be the moon, in anticipation of the total lunar eclipse. The sky was
mostly overcast all day, with the sun peeking out occasionally during the
afternoon hours. About 6:00p, I observed the moon rising over the
housetops, veiled in a thin layer of clouds.
The bright moon combined with the haze and clouds resulted in a small
"ring" around the moon. I was getting disappointed in how the day was
turning out. But I consoled myself in the fact that at least I'd be able
to watch Earth's shadow transit the moon, if not see the reddish hue.
I took another look outside about 8:00p. T minus 1 hour before the
eclipse. Was it my imagination, or did the moon look brighter? Quickly
scanning the rest of the sky, I noted that I could see some stars beginning
to show through! The sky was clearing off! Maybe this would be a good
night after all!
Shortly after 9:00p now. Looking out my bedroom window, I noticed that
the lower-left corner of the moon was just beginning to look like it
was slightly mishapen. I have to give Chris Marriott credit, his SkyMap
program was within a couple of minutes of being right on target for the
start of the eclipse. At this point, I was still debating whether or
not to take my telescope outside and brave the cooling temperatures.
At about 9:45p, the moon is about 2/3 covered in shadow and is
definitely taking on an orange-brown hue. The good news is that now the sky is
almost completely clear. The bad news is that this means the
temperatures will start dropping steadily now. I decide that the opportunity is
too great to let it slip, and begin packing up my telescope for
transport outside. After all, this will be the last total lunar eclipse of the
millenium from my location.
So I quickly grab my scope, bundle up, grab a thermos of hot chocolate,
and head outside, where I set up in my 2-man dome tent that I have
rigged up as a portable observatory (see
http://www.iolaks.com/softech/observe.htm for more info about that).
The moon is now at about 90% totality and darkening fast. Wow, the vivid
color transition from the lower-left corner (dark brown-red) to the
upper-right corner (still shining white) is incredible! I think this is
the best lunar eclipse I have ever witnessed.
I view the last few minutes before totality with my refractor at low
power (35x), which gives a good complete view of the moon in the eyepiece
and allows the color contrasts to be better seen than with the naked
eye.
Around 10:00p (I keep forgetting to look at my watch), the last of the
bright white glow of the moon has disappeared, leaving a dark brown
moon. It's amazing how much smaller the moon appears when it isn't shining
like a searchlight in the sky.
What's this at the edge of my eyepiece? It looks like...yes...it's a
star! In the same field of view as the moon! And now more are appearing!
One of them, which I later identified as SAO 97665, is listed as a mag.
8.4 star and is only about a moon's radius away. The seeing must be
pretty good by now, for my cheap department-store scope to pick up such a
faint star so easily. I'm not even having to use averted vision on it.
After trying to see how many features I can still make out on the
darkened moon for a few more minutes, I turn my scope toward nearby M44 (The
Beehive Cluster), which easily resolves into several doubles and
triples. I'm still in awe of the fact that an hour earlier, the moon was so
bright that I couldn't even spot Castor and Pollux in this part of the
sky, and now I was able to see stars as dim as mag. 9.
For the next hour or so, I jumped back and forth between viewing the
moon and slowly sweeping the telescope across this region of the sky.
Then I wandered back over to the moon for good and tried to watch the
moment when I could glimpse the first piece of unshadowed lunar surface.
The lower-left edge of the moon began to get brighter, which caused the
top edge of the moon to be even less noticeable than it was during
totality. Finally, a small white sliver appeared. Due to the darkness of
the rest of the moon, it was almost blindingly bright.
As the minutes ticked away, I was able to make out more and more
details of the moon. I continued watching until the moon was about 1/3 out of
eclipse, then decided that I really didn't want to catch cold, so
packed it in for the night and watched the rest of the eclipse from my
bedroom window.
All in all, it made for an excellent night of observing, and it's not
often that you can see the Beehive when a full moon is in Cancer.
