NGC-7000, commonly called the North American Nebula, is located in the constellation of Cygnus the Swan, just 2 degrees east of 1st magnitude star Deneb (Alpha Cygni). It is a vast interstellar cloud of inonized hydrogen gas, covering an area of the sky 10 times the size of the full moon. However, visually it is extremely faint, and can only be seen naked eye from an extremely dark sky site. NGC-7000 lies 2500 light years from Earth and is over 140 light years in diameter. It was discovered by Sir William Herschel in 1786. It was dubbed the "North American Nebula" in 1890 after the pioneering astrophotographer Max Wolf noticed its distinctive shape in a long exposure photograph.
