My plan this evening was to tackle the Herchel 400 objects in Coma Berenices and one Caldwell object in that constellation.
I started off with NGC4559, a faint galaxy framed by two 12th mag stars. It was quite faint, almost twice as long in the SE-NW direction as it was wide. There was a 13th mag star near the center. No real structure could be determined.
Next was the Caldwell object NGC4889 a 11.4 mag galaxy. I'm not sure about the magnitude as it was was much, much fainter than the mag 12.9 galaxy NGC4874 visible in the same FOV. Had a bright core, haze extending out in the E-W direction visible using averted vision.
These faint objects were nice but I realized that I really wasn't in to spending the night looking at 11th and 12th magnitude galaxies so at this point I decided to scrape my plan and look at some nice bright objects. There were quite a few Messier objects that I had seen for the first time during the Messier Marthon but had never really spent time looking at so I decided to spend some quality time with them. I observed M92, M57, M14, M12, M10, M107, M19, and M101. My observation of M57 during the Marathon had been so quick that I really didn't appreciate how great an object it is. It was definitely the highlight of the evening and I spent a lot of time trying different magnifications. I was unable to resolve the central star but it was still great to look at.
I finished off the evening with a few more Herchel objects in Boo and Crv, NGC5446, NGC5248, NGC4038, and pNeb NGC4361. I finally pack it up at 1:55am but was too excited about the evening to sleep. Finally dozed off sometime around 3:30am and dreamt of the stars.
