This region of the sky, in the approximate middle of the constellation Cygnus, is brimming with clouds of ionized hydrogen. In this image I have located the bright star Sadr just out of the field of view to the lower right, and highlighted a butterfly shaped section of the nebula. But truthfully, it is hard to point to this section of the sky without getting some interesting and captivating shapes in your field of view. This was imaged in RGB and Hα, with the Hα mixed in to the red channel to add some sharpness and detail. In retrospect, I might have also captured OIII and made a 'proper' bi-color narrowband image out of this as well.

The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae. Sadr itself has approximately a magnitude of 2.2. The nebulous regions around the region are also fairly bright.
Here is a famous object, called the Pelican Nebula (even though I think it looks more like a Pterodactyl :) ). This object is frequently imaged along with the North America Nebula, which is a brighter area of nebulosity out of the frame to the left and above. This is shot in narrowband and mixed using the SHO palette. Extra data was taken in the 2 fainter narrowband channels (OIII and SII) to mitigate noise. The stars were added from a very small amount of RGB data. The data was taken unguided.

The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name.[1] The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbor, the North America Nebula, by a molecular cloud filled with dark dust. The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds.
This is the Fishhead Nebula (IC 1795), an energetic star forming region shaped like a fish, which is part of the larger Heart Nebula. This is mixed in a modified SHO palette. Melotte 15 is also seen in the upper portion slightly left of center.
