The heart of Cygnus is a very colorful part of the sky. Only a portion of the large emission nebulosity (IC 1318), the Butterfly Nebula around Sadr, Gamma Cygni, is on this image. The dark nebula (LDN 889) to the right of Sadr, seperates the two halves of the Butterfly. The open cluster NGC 6910 is just to the lower left of Sadr, with some other small clusters in the nebulosity.
