Description

Pacman Nebula (NGC 281)

My attempt at the Pacman under an almost full Moon, using the L-eXtreme filter. My processing skills are slowly improving using APP for stacking the two separate sessions and Photoshop for the cosmetic edits. My noise reduction has previously been too aggressive and I think I've improved on this target. The first version is processed as a RGB stack but I will reprocess this as HOO to bring out the OIII signal in the central region.
