Crescent Nebula Panorama

The Crescent Nebula (NGC 6888) and the surrounding gas and dust clouds in the constellation Cygnus, photographed in H-alpha. This was a 6-pane mosaic created with the aid of Telescopius, a wonderful program. The image spans about 5.2º x 5.3º, so roughly 10 full moons in each direction. Sometimes a bigger bite is better.
