The North American Nebula Complex as it resembles the Continent of North America, this is one of the largest stellar Nurseries (Star Formation Regions) in the Northern Sky, visible to the unaided eye from a dark location, but looks much better in Binoculars! The Complex is about 1800 light years distance from Earth, and it spans ~ 50 light years across or ~300 trillion miles across.
Also visible in the image is the Pelican Nebula right, & the Bright Blue Star at the top right is Deneb or Alpha Cygni in the Constellation of Cygnus “The Northern Cross” or “The Swan”.
