Description

Revision: C

Title M45, Less processed and more thoughtfully combined

Description The first version suffered from star bloat and over-processing, and it took trying to identify IC 349 to realize how bloated they had become. This version went back in processing to doing the LRGB combination of Starless images, then screening in RGB Stars last. Better care was taken to not over-stretch either component.
