Description

The Dumbbell Nebula was one of my first narrowband motifs in 2018. Now I have extended the single exposure times and could also dither with ATP.

During the processing I had the impression again that the assignment RGB = HOO is not optimal. The green channel here is a 50/50 mixture of H-alpha and OIII.
