Description

Lesson learned on this one. I dont think I will be battling the Moon again with my Luminance filter. The luminance data had reflection artifacts that I found next to impossible to deal with, even with PixInsight's DBE. I still felt this one was worth posting and have always liked this grouping of galaxies.

Revision B is annotated in PixInsight.

Revision C is a reprocessed version using my luminance but repaired by PixInsight wizard David Ault. David created a "false flat" from the luminance and repaired the artifacts that my flats did not fix. This allowed me to stretch the image much more than before since I wasnt trying to hide the artifacts. Thanks again David!!
