Description

This was first light for my new Astro-Tech AT8RC, as well as my first time trying to process with PixInsight. 1st revision looks a little grainy for my taste but it was fun to experiment. I might try to reprocess with just my usual Photoshop workflow and see if it comes out better.

2nd revision... added some earlier data from a night where I forgot to adjust my CCD temperature to my usual -20C setting, but it did seem to help a bit.
