Cocoon Nebula

The Cocoon Nebula (IC 5146, also Caldwell 19) is located in the constellation Cygnus.  Dark nebula Barnard 168 extends from the Cocoon Nebula to the edge of this image.

Heat is one of the worst enemies of imaging chips.  I do not have a rig to keep my DSLR cooled down, and it was VERY hot the night that I imaged the Cocoon Nebula.  There was a significant amount of noise in each of the subs.  I removed a lot of the noise, but I think that the overall image quality suffered pretty terribly.
