ASTRO: M-3 Globular Star Cluster in Canes Venatici

I've not had much time for imaging of late, but here's a short exposure from
July 2007. It's a little noisy since it's only three 5 minute exposures
(RGB). Taken with SBIG STL-1301E CCD camera, Kopernik Observatory's 20-inch
RC, and my home-made focal reducer cutting the scope down to about F/5.

That's one that keeps escaping me. Like M13, I just posted, I keep
taking it to no avail. Now it's too low. I'll try again next year. My
seeing just isn't up to globulars but a couple times a year.

George, good result in such a short time. Looks a bit too red to me but it
nicely shows the different populations of stars in a glob.

Rick,

It was pretty low when I did this image back in July. I was really after
a comet that was near the cluster, but the comet image came out poorly.
