‘Bubble Nebula’, NGC 7635 in Cassiopeia
Astro-modded EOS 600D,12” Newtonian telescope
42 x 4-minute ISO 1600 auto-guided exposures taken over 2 nights
Frames stacked in Deep Sky Stacker software.
Result post-processed to increase contrast, reduce noise, adjust overall colour balance and reduce colour gradients caused by light pollution.
I also used Starnet++ to temporarily remove the stars during processing (as otherwise they dominate after stretching the contrast).
