IC 1318 (Butterly Nebula), NGC 6910, Sadr, Cygnus
IC 1318 is a large emission nebula located just east of Gamma Cygni (Sadr), a bright class F8Ib supergiant star forming the center of the Cygnus cross. To the north of Sadr lies a small, young star cluster NGC 6910 which is thought to be a part of the emission nebula complex. IC 1318 is divided by a dark foreground dust lane giving it the appearance of butterfly wings. Distance estimates for IC 1318 and NGC 9610 are 3,500 LY, and for Gamma Cygni in the foreground 1,800 LY.
