Description
This is the longest integration I've ever done and was an extremely challenging processing effort for me; one which required learning a lot about blending techniques. It was captured over a good chunk of nights from November-February from my Bortle 7/8 backyard in Milwaukee, WI using both an ASI533MC (RGB) and an ASI533MM (Lum + Ha).1344x90 - UV/IR Cut - ASI533MC -RGB
