Date and time of Observation: | 3/18/03 1900 - 2100 EDT |
Observing Location: | Chelmsford, MA (USA) |
Object Observed: | Jupiter, Saturn, M42 |
Viewing conditions: | fair |
Telescope | Meade ETX-90 OTA on home-brew mount (90mm M-C) |
Eyepiece | 26mm SP, 15mm SP, 2X Barlow |
Observing notes: |
Saturn was small but obvious in the 26mm
Super Plossel with Titan also visible. Switching to the 15mm increased
the size and I could just make out the Cassini division in the rings.
No detail on the planet itself. Adding the Barlow didn't help -- the
seeing wasn't that good tonight.
Jupiter and its four major moons were lined up nicely. I could see the
two temperate-zone cloud bands, but the red spot (which I've yet to
see) was on the opposite hemisphere. Again, I could push the scope to
about 96X (26mm plus barlow) but trying for the full 167X was beyond the
current sky conditions.
M42 is always fun to watch. Best in the 26mm alone, I find. I tried
to resolve the trapezium by switching to higher power. I know I saw
three of the four stars, but I don't think I was able to split off the
fourth one.
Comment: I've been doing astronomy for only a few months now. First
light was Alberio last August -- that was enough: I was hooked!

Object Observed: | M42 Jupiter Saturn |
Viewing conditions: | Average |
Telescope | EXT90EC |
Eyepiece | 26mm Plossl |
Observing notes: |
We just had our butts handed to us 7-2 (ice
hockey) so I pulled my ETX out of the car and set it on the now empty
cooler. We started off with planets; 6 bands on Jupiter, 3 moons of
Saturn were visible to my surprise.
Then I got lucky and found M42 in my viewfinder. Surprisingly good
contrast and pretty clear delineation of the nebula for a light polluted
Parking lot. I'll have to give it another look at home in the country w\o
all the light pollution. |

Observing Location: | co Galway, Ireland |
Object Observed: | M1, M81 and 82, double cluster, auriga and gemini open clusters and an occulatation |
Viewing conditions: | Excellent |
Telescope | Meade etx-90/ec |
Eyepiece | 26mm plossl |
Observing notes: |
I started off with M42, it showed definite mottling, the dust within it
was silhouetted Nicely by the nebulosity. It was about 40 arcminutes across.
Next I went on to M81 and M82. Both of which fit nicely into the fov. Both seemed to have some
structure when I used averted vision.
I then used the autostar's tour function for a while. It suggested M79
- a moderate globular in lepus. It was a niice view but M 79 was just a
fuzzy.
I then had a look at M1, it seemed larger than I remember it, I really
like M1 I suppose i'm fascinated at the story of it and it being visible to the
naked eye in 1054.
Next I did the run of open clusters, first I had a look at M35. This
is my favourite open cluster along with the double cluster. It seems to have an
infinite amount of stars, there seemed to be at least 100 Stars in the fov.
Next came several more M36, M37, and M38. All of these are nice
clusters as well and seem well suited to a wide field eyepiece.
I next had a look at M31, it seemed quite large ( I traced it for 2
degrees).
Next I had a gander at M33 which is quite a difficult galaxy I think
due to its low surface brightness.
Last but not least I was M51 and its attached galaxy NGC 5195, I
found M51 quite hard to see although I do have a bad north horizon.
To finish up I just watched my first ever lunar occultation at about 7 o
clock this evening (the 1st).
It was amazing the star was 30 piscium. I'm now waiting for 33
piscium to be occulted.

Astronomy on the Algarve.
It only seems like minutes since my first observing report from Italy. A week of cold weather coupled with a
forecast of rain, rain and rain sent my wife into a frenzy of net surfing and phone’ calls which resulted in a
late booked week ‘somewhere’ in the Algarve.
Arriving at 3 a.m. I could easily see Scorpius and Sagittarius standing high through the lights of Faro
airport. This set the scene for six more nights of clear skies and darkness through the new moon period.
My first brief session was from the deck of an empty beachfront bar/shack well sheltered from wind, spray and
light pollution. At this latitude Mercury was well above the horizon at mag. -0.3 in rapidly darkening
twilight. No grubbing around amongst the trees and houses in the northern twilight and light pollution
of Manchester for me! Phase detail was seen at x128. The galaxy Centaurus A could be discerned as a large
haze with nearby stars whilst omega Centauri appeared as a massive globular, both crying out for more aperture
and altitude.
It turned out that ‘somewhere’ in the Algarve was about 20 minutes drive from COAA. I was welcomed there the
next day, watered and given a tour of the excellent observing facilities and accommodation. I certainly hope
to holiday there soon however, you need to book early to get a place during dark sky periods. Bev. also
pointed out an excellent nearby observing site for me to use.
I drove to the site that evening. It was at about 800 meters and had a commanding view of the whole of the
Algarve. After re-visiting omega Centauri/Centaurus A I was about to turn my attention to some overlooked
Caldwells in Canes Venatici when the RA/Azimuth drive on the ETX failed! Forced into using more traditional
methods, brain and eyes, I managed to track down the following objects. All could be found from nearby bright
stars. Starting with Antares a quick scan found the enormous M4 and condensed M80 globular clusters. The
Table of Scorpius dimly seen in Italy was a wonderful, small bright open cluster at mag. 2.6. M13 in
Hercules was found but at a neck breaking angle for locating in the straight through finderscope on the ETX.
M57, M58 and M29 in Lyra and Cygnus followed. The big naked eye clusters of M6 and M7 were easily seen in
Scorpius. I spent the remainder of the session wallowing in the splendors of the Milky Way around
Sagittarius.
So, in astronomer’s paradise and no GOTO! Fortunately, back in the apartment, I had some half-sky maps
showing Messier and Caldwell availability and some small FOV, detailed finder charts left over from my
previous trip abroad. A couple of hours sketching lines, triangles, parallelograms and estimating distances
resulted in a list of 75+ targets to try for. I also thought through a vague sequence that would avoid
having to crane my neck at painful angles when trying to find objects at too high an altitude.
I started at about 10 p.m. local time. Setup was very quick without the need for accurate leveling or any
alignment routine. The scope’ slews very smartly by hand as well! I quickly found M13 at 50° elevation in
the darker eastern sky. M92 followed using a parallelogram constructed out of part of the Hercules
‘plantpot’. The Beehive was dimmed somewhat by the twilight in the west and it took a few minutes to
pick out M67 as darkness prevailed. The benefit of the southern location was immediately noticed when
M68 a mag. 8.2 globular and M83 a galaxy low down in Hydra were easily found using Corvus as a pointer
constellation. M65 and M66 in Leo were found first time in Leo mid way between two bright stars.
I don’t know what happened to M95 etc. though. It proved very difficult to orientate correctly for
any object far from bright stars that could be placed in the finderscope field. A quick spin round and
M108, M97 and M109 were spotted near the bowl of Ursa Major before disappearing behind the trees. The
Sombrero galaxy proved a difficult find in Virgo, far from bright stars and using a large, virtual
right-angle triangle to find. After some sweeping the familiar asterism, known as Jaws, and galaxy
slid into view. I realised that I had forgotten M81 and M82, these were nailed first time. The dark
sky made this much easier with hazy objects sometimes just catching the edge of the eyepiece FOV. The
dark sky also allowed a naked eye observation of M13 later in the night. A first for me and indicative
of a limiting magnitude in the 6+ range for keener eyes. But, it didn’t help me unravel the Virgo
clutter, abandoned after 15 minutes of fruitless searching. The easy globulars M3, M53 and M5 gave
some respite. I had missed M5 previously wandering around Libra by mistake! The constellation of
Ophiuchus had always been a mystery to me but with the good, dark skies and maps the constellation
and globulars therein soon revealed themselves as impressive objects.
I then returned to the ground covered during the previous session. Messiers in Scorpius plus Caldwell 75,
a fine mag. 5.8 open cluster. The globulars along the base of the Sagittarius teapot, M69, M70 and M54 were
easily seen. M54 particularly bright and condensed. M22 and M28 are by the lid of the teapot. Lagoon and
Triffid nebulas made up steam puffs from the spout. By this time the Milky Way was stretching across the
whole sky as a frozen cloud. The Small Sagittarius star cloud, M25 and M23 made for fine sweeping all in
a row. The Eagle nebula caused a problem, the nebulosity was so bright I didn’t identify it initially and
kept trying to make out the upside down tick of the Swan nebula instead! The bright star clouds made Scutum
difficult to identify however, the Wild Duck cluster was striking enough to pop out from the background.
Returning to the north west another silent, quick spin with the scope’ M51 and M101 in Ursa Major and
galaxies M63 and M94 in Canes Venatici were low enough for easier viewing, but still difficult finding.
Back to the east where Messiers in Sagitta, Lyra, Cygnus and Vulpecula were found and identified. All
tricky against the Milky Way background with tired eyes. To the south, drawing a line through the teapot
and beyond took me first time to a four star asterism on the border with Capricornus. This was fortunately
on a detailed finder chart for M55 and M75. These had been very difficult with the Autostar in a hazy, low
altitude position in Italy but were clearly picked up here. Moving the scope’ and tripod to allow a clear
view of Cassiopeia the open clusters of M103 and M52 were ticked. The bright globulars of M15 and M2
provided suitably easy targets as my head, eyes and back told me they had had enough. The rising M31
and M32 galaxies in Andromeda provided the final easy pickings.
In all I managed to find and observe 60 Messier and 2 Caldwell objects, plus numerous double stars, Albireo,
Cor Caroli etc. during this 5 hour session. Messier Marathoners try to find the full 110 in one long dark
night in late March. Any takers for the Algarve next year?

What I saw on my holidays
A two week stay south of Florence, Italy presented the opportunity to observe many of the more southerly
objects on my many ‘tick’ lists. I used my ETX90 EC, this I carried as take-on luggage for the flight
down to Italy.
The first session was on a warm humid evening. Now I understand what these Americans have to suffer
it was too hot! The downside being very poor seeing with crud extending about 15 degrees above the horizon.
I hoped to pick off some bright open clusters from the Caldwell list in Canis Major and Monoceros. These
were lost in the evening twilight and murk. The seeing was so bad that I could barely make out the Ghost
of Jupiter, a mag. 8.6 planetary nebula and the Spindle and Needle galaxies at around mag. 9. The rising
moon put paid to any more observing that evening.
Five days later things were looking better. A day of heavy rain showers followed by a cool cloud clearing
north-easterly breeze boded well for a good session. I was not disappointed. From my observing site at
about 1000m. elevation I experienced the clearest conditions I have ever seen!!!
The Coma Berenices star cluster was a brilliant cluster of stars near the zenith, better to the naked eye
than the Beehive! I started in the deep south by Hydra, Sextans and Corvus. The seeing made the Ghost of
Jupiter jump out of the eyepiece as unmistakably not a star. I tried the UHC/Deep Sky filters that Roger
had lent me however, despite increased contrast the overall view was not improved. The Spindle galaxy was
this time bright, obvious and very spindley. M68 and M83, difficult from the U.K. were obvious, though
unremarkable. The big ticks here were the two interacting galaxies NGCs 4039 and 4038 in Corvus, visible
as a lobsided blob. All the better for knowing what they are and how they look in pictures. On familiar
ground M67, the ‘other’ cluster in Cancer, looked far better through the scope’ than the Beehive, which
needs a wider FOV than that available through the ETX. Skimming through Leo the ‘trio’ of galaxies looked
excellent with the two vertical Messier galaxies hanging below the fainter horizontal NGC something. A
check on the Sombrero, M104, showed a beautiful setting with a nice asterism to the west and I could easily
imagine a dark lane running along the middle of the galaxy. Moving up to Coma three galaxies from the
Caldwell list half seen, half imagined from the previous session were so clear that I could not believe
I was looking at the same objects. Despite having finder charts from SkyMap Pro which confirmed all the
observations!
Next I tried higher powers on the big globular clusters M5, 92 and 13. M92 readily resolved at the edges
whilst the others looked bigger and granular. M51, the Whirlpool galaxy was simply stunning, so bright
with haze extending around it and over to the associated galaxy. I then notice that Vega was quite high
and decided to try epsilon Lyrae. This double double split readily and the seeing easily accepted x256.
Hopping down to the Ring nebula was a breathtaking find with it being so clearly defined at x128. The
Dumbbell was equally spectacular.
Finally I ticked a few Messier globulars in Ophiuchus, not impressive owing to their low altitude.
Reluctantly I had to end the session at around midnight with Scorpius rising from the horizon.
I had hoped to finish off a complete round of the Messier list whilst I could see the southerly objects
from a favourable location and so a few days elapsed waiting for the moon to wane and a clear night to
appear. Fortunately following some thunder storms the skies started to clear two nights before we were
due to return home.
Starting at about 00:30 local time this was to prove quite an arduous session, even with the aid of the
Autostar and detailed finder charts. The sky gradually cleared throughout the next four hours however,
a lot of the time was spent low down in the south and south east trying to pick off the objects as they
rose through a light haze. The globulars in Ophiuchus passed by easily, I’m sure they warrant further
viewing in an August evening. The big open clusters in Scorpius looked the part as they rose to about
15 degrees. The Butterfly was true to it’s name. A bright mag. 2 cluster, the Table of Scorpion?, was
also seen in the haze of 3 degrees altitude. The Wild Duck cluster in Scutum was also a gem. Then I
moved on to Sagittarius.
The sights to be seen here cannot be underestimated. Staring into the centre of our galaxy for the first
time was a profound experience. Eagle, Swan, Triffid and Lagoon nebulas plus a feast of stars. Reason
enough to travel south in the summer.
Difficult low altitude globulars followed with lots of averted vision and scope’ joggling, led to a touch
and go final tick of M30 in Capricorn through the morning twilight. Thus endeth a fine holiday experience.
The use of the Autostar combined with excellent finder charts has certainly made it possible for the
beginning astronomer to travel the universe. Now I’ve got to learn to do it without
