Cygnus is a pretty interesting chunk of sky because of the milky way that runs right through the constellation, and the nebulae present, including the Pelican and North American that are both visible near Deneb in the lower left corner of the frame.
The 50mm lens was just wide enough to capture the tail and wings of Cygnus, although the head had to be left out in order to fit the more interesting nebulae near the tail.
