IC1318 - Butterfly Nebula (Ha)  
Cygnus

Diffuse emission nebula surrounding Gamma Cygni star (Sadr). 		 
 
Sadr lies in the center of Cygnus' cross. IC1318 is one of the surrounding nebulous regions, others include the Butterfly nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.

This is a large area of emission nebulosity. Stretching more than 2 x 3 degrees here, the nebulosity actually extends far out of the photo. Most of the nebulosity is fairly faint.

The two sections of nebulosity to the left of Gamma (the brighter star on this picture) are called the Butterfly Nebula and have the catalog designation of IC 1318. LDN 889 is the large area of dark nebulosity that separates the two halves of the Butterfly Nebula.
