Triangulum Galaxy, Orion Nebula, Flame Nebula, and Horse Head Nebula

21 December 2021

I already wrote about the problems I had when taking, or rather processing, these images. As there is no way to remove the colored concentric rings, I tried my best to hide them. All images were taken using the same setup:

M 33 Triangulum Galaxy | total exposure 27 x 5min
M 42 Orion Nebula | total exposure 54 x 2min
NGC 2024 Flame Nebula and Horse Head Nebula | total exposure 54 x 1min
