The Pelican Nebula was my first light image with the ASI533MC camera and ASIAIR controller. The data was taken under city light pollution and a full Moon up with a light pollution filter (Optolong L-Pro multi-band CLS) so even with over 2 hours of exposure, noise is a problem. In this rework I'm trying out more aggressive linear noise reduction in PixInsight as well as a final noise pass in Topaz DeNoise. Therre is lots for me to learn here. This first image uses 192 30" subs and Topaz DeNoise post processing.

Along the way, mistakes were made and lessons learned. The image below shows how things can go bad with overly aggressive noise reduction during linear processing and too much compression in post:

A crop of the Pelican Nebula taken during the full Moon, early morning 2020-08-03 from Austin, Texas, exposured in 30 sec. subs and 30 darks, gain 101 (unity++), at a temperature of 10C. Photographed with a William Optics RedCat 250/51mm telescope, Optolong L-Pro broadband light pollution filter, and a and ZWO ASI533MC Pro one shot cooled color camera.
