The Continent & the Bird

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus that resembles the shape of North America and The Gulf Of Mexico. It lies at a distance of approximately 1800 light years away from us.


This image contains other objects like the nearby emission objects Pelican Nebula (IC5070), the faint emission nebula IC 5068 and the Cygnus Wall.


This object has been captured using a QHY16200A 16.2 Megapixel CCD camera mounted on a William Optics Redcat 51 APO. Data acquired by Terry Hancock from Grand Mesa Observatory.


Hubble Palette version (SHO): H-Alpha mapped to green, SII mapped to red and OIII mapped to the blue channel. while the colors in this image are not the true colors, the narrowband filters were used create the nebula color. Then I added the natural star colors using RGB filters and Starnet process.
