NGC 7000 - The Cygnus Wall

Show astrometry data

The Cygnus Wall, a portion of the North American Nebula (NGC 7000) in the constellation Cygnus. The nebula is approximately 1,500 light years from Earth, and the Cygnus Wall spans about 20 light years.

The image was shot through narrowband filters, and maps Sulfur 2, Hydrogen Alpha and Oxygen 3 to R, G and B respectively, comprising approximately 24 hours of 20-minute sub-exposures. Additionally about 90 minutes of short RGB exposures account for truer star colors overlaid on the image. Processed using PixInsight and Photoshop.

Data collected at the Dark Sky Observatory Collaborative (DSOC) in Ft. Davis, TX using SC Observatory's remote Planewave CDK 17" f/6.8 scope, in collaboration with:
