I was able to get set up last night and capture a decent image of the Leo Triplet. The seeing was fair with some moisture and freezing temperatures so I had some frost to chase away. Guiding was not the best possibly aggravated from the location in the southern sky. Different areas of the sky have inherent atmospherics often discernible from the tell tale twinkling stars. They may look pretty, but they indicate thermal instability that make things appear to move around. This drives guiding crazy and is referred to as ‘chasing seeing’. This was stacked from 22 frames of 220 seconds each or about 1hr 20 min total. Using dithering again with no dark frames. I need to try some comparisons with some dark frames I guess but this works surprisingly well.

The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away[5] in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.
