Description:
 The region around the star Sadr, also known as Gamma Cygni, is full of emission nebulosity (designated IC 1318B).  IC 1318B is located within the constellation Cygnus and is close to other famous landmarks along the summer Milky Way, like the Pelican and North American Nebulae, the Crescent Nebula, and the Bubble.  This area is very rich in stars, hydrogen emission, and bands of opaque dust.  Feel free to check out the links to the vertical orientation listed above.
