Part of the larger “North American Nebula” emission nebula, aka NGC 7000, the Cygnus Wall is the luminous section, captured in true color with a light pollution filter to help highlight the gaseous portions. The billowous pink clouds are the active star-forming hydrogen regions, and the lighter blue background are areas primarily composed of oxygen. This was my second image taken, similar to my attempts with the Crescent Nebula, I captured the Cygnus Wall both with a narrowband filter in place and without.
Cygnus Wall, North American Nebula (NGC 7000)
Captured with a narrowband/light-pollution filter in place. Moreso than reducing the impact of skyglow, the filter serves to drastically minimize foreground stars and allow the emission nebula to stand out.

Cygnus Wall, North American Nebula (NGC 7000)
When not using any filters at all for light frames, faint targets like NGC 7000 in areas with many stars (which would include pretty much anything within our own galaxy) become very challenging to properly highlight as a foreground subject even with heavy-handed star reduction.
