Open cluster sketch, 8/13/09

-It's not a Messier.
-It was a little past culmination when I sketched it.
-It was south of the zenith from my location at 41Â° N.
The directions might be hard to see (I had to draw them in with MS Paint) but north is up and east is to the left.

Let me know what you think, and don't be afraid to throw out a guess even if it's completely random.

I've switched out the poorly done invert for a better one but apparently editing pictures in GIMP triples the file size so I had to link to it instead.

NGC 6633 in Ophiuchus. I've always loved this one because the brightest stars form a chain running nearly east to west and their beautiful blue colors. It's also in the same area as a couple of other wonderful open clusters, IC 4665 and IC 4756.
Supposedly it is a naked eye cluster in a dark enough sky but in my mag 5 back yard it's just barely visible in my 8x50 finder scope. Still a nice sight in large binoculars though.

Next time I'm out I will have to take a look at this OC as its on the Best of the NGC. It looks like you really captured the various chains of stars here. Nicely done and thanks for the prep!

Nice sketch. I struggled with this one for a while and then gave up. I have observed this one but never sketched it.
