After seeing the S&T site that Matt pointed out at on his blog, boyruageek, I googled. Found this when I googled on my blog name and astronomy. (Yep, I do that from time to time, I'm afraid to say.)

And more funny, a press release reads from davep:
"Dave Pearson pressured out public stock holders at a total cost of B$2,174.11 using a Telescope (artefact)"

--------------------------------------------------------


Saturday was a warm, beautiful day. The sky was clear during the day, but there were differing weather forecasts. I happened out around 8:00pm to see that it was clear, so I put my money on Clear Sky Clock. Taking the same observing pack I tool out last night, I set out to TotL for another night of observing. The air was still warm that I dressed in sweater and turtleneck, carrying my coat for later in the evening. Once again, I thought for sure others would be out but I observed mostly on my own. A nice way to get back in the groove and feel the *zone*. Around 10:30pm, it would become busy with pedestrians coming by.

This night I felt more productive than the previous day. Perhaps, it was because the increased number of objects observed but hopping was much more fluid. Armed with Karkoschka's atlas, and PleiadAtlas on the Palm Tungsten T3, I had a plan. I concentrated on Canis Major. Sirius was situated well a bit east of the Citibank building; this is nearly celestial South.

I open cluster-hopped from M41 south to Collinder 121, east to NGC 2354 & NGC 2362, and further east to M93. At the time I was observing M93, Hawaiian George appeared. We observed Saturn & M44, and then back to M41 as a comparison for size, brightness, and stellar richness. To me, M44 exhibits a greater range of brightness than M41, as well size and quantity of visible stars through binoculars. I could easily count 28 stars in M41 compared to the 40+ stars in M44. This evening, I couldn't see Rhea near Saturn, in spite of knowing where to look. Titan was bold situated to the East.

Collinder 121 was difficult to identify. Locating omicron CMa was a cinch, though looking in the field I didn't see any noticeable concentration. Referencing PleiadAtlas, I could see the scattering of brighter stars with omicron CMa to the North and an obvious broken line of stars running South. I searched along east long that line. At reported 50' in size, this should be huge. I've yet to research this but I would say to pass on this cluster unless one wants to complete a list.

While nearby, I went South to Adhara, epsilon CMa, a double with a 7.5" separation according to Karkoschka. I was unable to resolve.

One of favorite open clusters in the telescope is NGC 2362, tau CMa Cluster. I think I've seen it referred to as the "Mexican Jumping Cluster". It's a beautiful, tight compact cluster of diamond dust surrounding bright tau CMa, most of the concentration to the east & south of tau CMa. However, through the bins, a lot is to be desired. I did count 7 stars surrounding the east-south-west, none to the north. Additionally, there was a faint haze below these stars, though difficult. While there, I noted that beta Lyrae-type variable 29 CMa appeared almost equally as bright as tau CMa, but slightly dimmer.

Nearby I tried for NGC 2354 but was unable to positively detect it. For that matter, I didn't even suspect anything. After spending some time hoping to dark adapt in the EP, I panned east counting about 3 field of views (~ 6°), when M93 appeared. It took me a while to id this cluster because I sort of lost my bearings. retracing my steps it was certainly M93. Only 2 stars resolved clearly, a third blinked to the north, with a very faint glow beneath. Compared with the urban background sky, this cluster was obvious despite that it didn't resolve well nor glow brightly. Again much more impressive in a scope.

Times Up came stopped by on their monthly Central Park Midnight ride. They were pretty thin with about 6 riders, Kin being one of them. I showed a couple of them the obvious sight and would collapse the tripod for one of the riders’ son. He got a little tour from Saturn to A beautiful sight of Orion's Sword to Sirius. Orion's Sword frames very, very, well in the Tak's fov. One can see NGC 1981 down to iota^1 & -^2, the nebula stood up well even though we were looking a bit west of Time's Square’s Gegenschein. Simply beautiful and thought provoking.

The crowd cleared and I was left to my own a bit past 11pm. I got courageous and hunted the brighter galaxies. Of the list that I searched - NGC 2841, M81, M82, NGC 2903 - only M81 & M82 were detectable in the bins. Seeing the sigma-sigma-rho triangle and 24 UMa naked eye, it was easy to land at where I needed to be. M82 appeared as unfocused star at first, making an almost equilateral triangle with 2 stars to the west. When looking for M82, which was extremely difficult, M81 appeared much larger than an unfocused star with averted as an extended glow. It was difficult to give it any orientation in length, rather it was ball~ish. M82 was glimpsed about three times with averted only, though I could detect that its orientation was nearly parallel with two brighter stars to the east.

My favorite astro-sketcher, Kiminori Ikebe captures a field similar to what I observed though his objects are brighter. NGC 3077 was not observed. Check out his English pages for some nice work. And for the adventurous or fluent, his Japanese pages offer much more.

Getting late, on my own, and seeing some clouds move in from the west I began to wind down. I did a quick hit in Auriga, glancing at Leaping Minnows, Cheshire Cat, M38 and M36. As I looked M38, a ribbon of smoke floated through the field. Looking up a cloud front was moving through. After seeing M36 totally resolved (and more attractive than M38), I tried for M37 but the clouds moved in. Stretching from West to Northeast, the clouds came making the decision to pack that much easier.

All-in-all a good 3 hours of observing and sharing. Bins are light, fun, and useful, but I like the scope much better. Being able to magnify and the larger glass grasping more light really enhances the experience. In spite of serving myself, I feel a little awkward when the regular passersby come through and all there is is the little package. My own aperture envy :^D

--------------------------------------------------------


Finally! After a seemingly long hiatus, I returned to TotL with a light observing pack to get some time beneath the stars. I traveled lightly with a backpack of bins and tripod, carrying the Coulter scope in its case thrown over my shoulder. Compared to the Teleport and Tak FS102, this is easy going! Setup is as quick as the Teleport.

Friday was a cold and surprisingly windy night. I thought for sure that Ben, Charlie, and Kin would be out because it was clear skies, but Kin & I were the only ones that showed. Even the passerby traffic was thin with occasional dogwalkers and some kids passing through. My skills seemed real rusty, too. I had to get some oil on the joints and eye-hand-coordination abck into swing. It felt that long!

Over the past month, I literally fell out of astronomy. The weather, holidays, work, and preoccupations pulled me away from anything astronomy, including blog reading, planetarium software, or just looking up. On Friday night I setup the bins pretty fast and threw them on Saturn to get them in focus. I was floored to see M44 and Saturn in the same field of view. Where have I been!! It was a total surprise to see this amazing sight. I left the bins on them for about an hour just soaking up that view, sharing it with the others, and softly scan the sky with naked eye.

In the Taks, M44 had three levels of stars: 30+ bright obvious stars; about dozen dimmer stars which required some effort; and, lastly the a background of unresolved glow. M44 is large, easily half the fov through the bins. Below was resolved Saturn floating magnificently with Titan and Rhea to the East. In contrast to the bins, the reflector CT100 with a 12.5mm EP, lost the background glow of M44. At least, I couldn't detect that same sensation. It did pull in Rhea much brighter and more obvious than the bins.

Afterward I hopped to Acubens, alpha Cnc, on my way to the other Cancri open cluster, M67, one of the oldest which exhibits nonconformity, as open clusters go. M67 was very, very faint and unresolved. No shape was discerned, just a soft low surface brightness glow against the background sky. 2 ~ 3 stars would blink, marking its location relative to other stars in the field.

Kin showed up and we chatted and observed Saturn through the RFT with different EPs. It was getting cold, so we packed up and left after Gregory visited at his typical witching hour on his way to work. We spoke of showing up at Carl Schurz Park the follwoing morning. Charlie had suggested we meet on Saturday morning to observe the old crescent Moon and sunrise. Turns out I slept until 9:30am and the sky was not the clearest.

As far as number of objects observed, it was awfully small - 3. I did abort an attempt to observe NGC 2841 with CT-100, but that would wait until the following night. The number of passersby was equally small. A great refreshing feeling to return to the night sky and meet up with friends and regulars I missed over the holidays.
