Messier 65 and 66

Two members of the Leo Triplet. 42 one-minute frames, 1600 ASA, automatic dark frame subtraction. Captured 59 frames altogether, but had to toss those with tracking error. Discovered the longest I can go in this fashion with a fresh battery is 3 hours, or a little over 90 one-minute frames using up 70% of my 1GB CF card.
