IC1318, The Butterfly Gamma Cygni Nebula

The constellation Cygnus is awash in nebulosity.  Point your telescope almost anywhere in the constellation and you’ll find something.  The usual suspects are the North America Nebula (NGC 7000), the Crescent Nebula (NGC 6888), and all of the pieces of the Veil Nebula.  But right at the heart of the constellation, at the center of the “cross,” there’s another beautiful area.  The picture below shows the area around the star Gamma Cygni, including IC1318, the Butterfly Nebula.  The whole area is swimming with emission nebulae, so it’s hard to say any single feature is a separate entity, but the Butterfly shape is fairly obvious.  The little open cluster at the top center is NGC 6910, but that hardly seems important given the rest of the image.
