July was a good month for imaging during the dark of the moon. I got 18 nights and took close to 400 subframes. One of the imaging projects was Sh2-171.
Sh2-171 and NGC 7822 is a young star forming region in the constellation of Cepheus. The nebula is said to be some 900 pc distant. Some of the younger components of the system are thought to be no more than a few million years old.
The color image combines (4) Narrow band filters with
(13) 1200 second exposures for each Cyan ( OIII ), Green ( HAlpha ), and Red ( NII + SII ).
