This wide field photo of the tail end of Cygnus was taken from a church field as a test for a potential dark site. Yard lights and heavy dew proved to be a challenge. The dew in particular meant I had to eliminate half the shots taken during the session. Despite these obstacles, the resultant photos turned out amazingly well.
This photo is a cropped frame from the original showing NGC7000 North America Nebula and IC5070 Pelican Nebula
