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.
