by Craig and Tammy Temple
This region of the sky is rich in HII nebulosity. The brightest star in
the image, Sadr (Gamma Cygni) lies at the heart of the constellation
Cygnus, although it is much closer to us than the nebulae. Just below
Sadr is The Butterfly (IC 1318), which is not actually two separate
nebulae, but a single cloud partially obscured by a dark dust lane, LDN
889. To the top right is The Crescent Nebula, NGC 6888. Several open
clusters and dark nebulae are also visible in this wide field-of-view.
