MASP day 4

We saw the horsehead! With an OIII filter, it looked like a slight darkening in the area where we knew the horsehead should be. Upon borrowing a hydrogen-beta filter, the horsehead jumped out clearly.

The Dynascope was a lot of fun. Even with only so-so collimation, it performed beautifully on many objects. I was particularly impressed with the view if the Veil. The scope didn't draw as much attention as I expected, but perhaps that will change after people have more of a chance to see it during he day.

I went after a lot of obscure objects. Conditions were truly ideal, so what better time for some faint fuzzies? However, around 1:30, dew became a serious problem. Everything on the field got covered in a hefty layer of frost, which looked particularly wintry when I got up at 7:30 the next morning. I finally turned in when my secondary frosted over.

My list:

M13
Ring Nebula
NGC 6894
Crescent Nebula (saw the entire ellipse!)
Veil Nebula
NGC 6891 (small planetary nebula)
Blue Flash Nebula
NGC 6956 (small galaxy)
NGC 147 (large, faint galaxy with small but very dense nucleus)
NGC 185 (small but fairly bright galaxy)
NGC 252 (small galaxy)
NGC 404 (beautiful view of a galaxy next to mag 2.1 yellow star)
NCG 6939 (open cluster)
Triangulum Galaxy
Flame Nebula
Horsehead
Abel 262 Galaxy Group
NGC 759 (small galaxy)
