NGC7000, North America Nebula

This is the North America Nebula (NGC7000). I spent 4 nights imaging this and ended up throwing out two entire nights of images (too much moon glow and poor seeing), ultimately using 7 hours of subexposures. This is a false color representation using a H(H+O)O color palette. The images were taken using a dual narrowband light pollution filter.

 

The cygnus wall is the W shaped brown/orange part of the nebula, lower right of center.
