Details:
The North America Nebula (NGC 7000) is an emission nebula in the constellation Cygnus. The name “North America Nebula” was coined by Dr. Max Wolf (ref: Burnham’s Celestial Handbook, Volume 2, by Robert Burnham Jr.) no doubt from his work with E.E. Barnard on dark nebulae. This image was processed by first removing the stars followed by processing the nebula.
The North America Nebula covers a region more than ten times the area of the full moon, but its surface brightness is low, so normally it cannot be seen with the unaided eye (Wikipedia).
