Description

NGC 281, the Pacman Nebula, in the hubble color palette. I tried doing 30 small stretches with star masks, then a masked stretch. It added some rings around the bright stars in the nebula. Deringing made it worse so I used curves to try and hide them.

Integration times per channel:

Ha 17x300"

OIII 20x300"

SII 18x300"

B

Description: I didn't like the first version. I tried using masks, and moved the color saturation levels around. It still looks a little overprocessed.

Description: Reprocessed again, but used lightness masks for noise reduction, and ArcsinhStretch. I normally use maskedStretch, but I always have trouble with the stars. I know I over saturated it, but I couldn't help my self.
