Crescent Nebula, NGC 6888, Cygnus
A Wolf-Rayet nebula around 5000 light years away, according to Wikipedia.
25 x 4-minute ISO 1600 auto-guided exposures, taken with an astro-modified EOS 600D & Revelation 12" f/4 Newtonian reflector telescope.
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).
