I arrived at Coe last night around 9pm. There were about 4 or 5 scopes already set up: Bruce Jensen, Michael D. (13" Coulter), Brian (homebuilt astrograph), and maybe one or two others. Lou, Bobby (12" LX200) and Jay showed up after I arrived.
Overall, it was a warm, dry night with varying amounts of wind, gusting to about 10mph or maybe a little higher (my skills as an anemometer leave much to be desired). The sky was not particularly dark and seeing was a somewhat soft at the beginning of the evening but improved into the wee hours. There was no problem with dew, nor was there any problem with dust.
I set up my 10" Meade SCT on the Losmandy G-11 and spent the beginning of the evening chasing down some galaxies in the Virgo Cluster. Due to the sky brightness, it was difficult to see the smaller, fainter NGC galaxies. Markarian's Chain didn't stand out as well as I have seen it from Dino. NGC 4550 and 4551, at magnitude 11.7 and 12.0 with surface brightness 12.8 and 12.9, respectively, were seen without much difficulty, but NGC 4531 (magnitude 13.0, surface brightness << 13) was at the limit of what was visible through the skyglow.
Next, I moved on to the globulars in Scorpius, Sagittarius and Ophiuchus. In general, I had more problems resolving the globulars which were lower in altitude -- I suspect the seeing toward the southern horizon was soft at best.
I ended the evening with the showpiece objects in Sagittarius -- M20, M17 and M8. I was most impressed by the Swan at 114x and an OIII filter. The faint nebulosity well behind and detached from "the swan" stood out nicely! Also, M8 at 76x with the OIII filter was spectacular -- the dark lanes were striking and the star cluster was sharp.
When I left at 3:30 am, Michael D., Brian and Bobby were still observing. The temperature was still in the low 60's, the wind had mostly died down and the seeing was much improved.
A wonderful night; thank you to Bruce and Brian for helping turn a potential disappointment into a rewarding observing session (I forgot my AP Maxbright diagonal at home and they were kind enough to loan me a diagonal and a 2 inch-to-1.25 inch adapter.)
