Great picture! Note the little Cocoon Nebula in the lower left corner!
Also note the slightly diffuse "binary nebula" surrounding the hot highly luminous O-type runaway star 68 Cygnus. This fairly large nebula, almost as large as the relatively well-known Butterfly Nebula (seen in the upper right corner here) is located to the lower left of the North America Nebula.
