The Pelican Nebula in Cygnus
Emission Nebula
Uploaded 9/24/16

Another test shot using the six inch Cometracker astrograph, this one is about 2 hours of exposure data from here in Payson, the night was dry and clear, but the wind was making a mess of the star images with poor seeing. Fortunately, the six inch only has a focal length of 22 inches, so it was far less an issue.
