Description

Two years ago, I was taking hundreds of subs of this target and after the last ones were done  - March 2021, I processed them and showed them here. Now I took all those files, selected the best ones of LRGB, HaOIIISII and processed them again with my current (improved) skills.

APP, PixInsight and Photoshop were used with the usual enhancmenet modules. A total of 370 subs with exposure time ranging from 30 seconds to 300 seconds - depending on filter, were processed - LRGB separate from HSO and at the end the stars from LRGB combined with the nebula from HSO.

In the list of equipment, I indicated only the last night, - in total I used 6 nights for all those subs.
