A Trilogy Of The North America Nebula My widest image of this region with this 3 panel Mosaic spanning an area approximately 2.5 x 5.5 degrees, captured using QHY11/TAK E180, presented here in H-Alpha, Hubble Palette and RGB with H-Alpha. 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. It contains some very interesting areas such as The Cygnus Wall which is representative of Mexico and Central America and the nearby Pelican Nebula (IC5070) which is not usually referred to as within The American Nebula however it is part of the same cloud of ionized Hydrogen.
