(Updated Dec. 2017)

The Crescent Nebula in Cygnus is an emission nebula with interesting surface patterns and wisps of oxygen (in blue) around the shell.

This is a much longer exposure than I had previously done on this target, and that plus extensive processing reveals some details not often seen in this nebula, such as the white cylindrical structures seen in the upper left portion of the Crescent.

Scope: AT111EDT at f/5.7
Mount: AP Mach1
Camera: QSI 683 at –20C
Exposure: 12 x 1800s H-a, 6 X 1800s O-3, 6 x 1800s S-2 (12 hrs total)

About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
