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.
