Supergiant star Gamma Cygni lies just outside the bottom of this skyscape, featuring a complex of stars, dust clouds, and glowing nebulae along the plane of our Milky Way galaxy. The field of view spans over 2 degrees (126.87 arc min, which is larger than four Full Moons) on the sky and includes emission nebula LBN 47, SH2-109 and the dark rift dark nebula, catalogued as LDN 889. The image is shaped like two glowing cosmic wings divided by a long dark dust lane, receiving the understandably popular name, the Butterfly Nebula (some of this is ref. http://apod.nasa.gov/cgi-bin/apod/apod_search).
The entire nebula complex of which this image is part, is illuminated by a solitary visually obscured class O9 star, and is referred to as IC 1318. It comprises three distinct visible components, IC1318 a, b, and c. IC 1318 b and c constitute a single giant HII cloud bisected by the thick obscuring dust (LDN 889) running between the two components (b and c). The bisecting dust lane is 20 light years thick and is physically bound to the emission nebula and its parent molecular cloud complex.
Though this immense HII region is located visually close by to the class F8 star known as Sadr or Gamma Cygni (in Cygnus the Swan), there is no true proximity between the two: the nebula's distance from Earth is estimated to be about 5000 light years, whereas Sadr is only about 750 light years away, and therefore not related to the nebulosity (ref. http://www.robgendlerastropics.com/IC1318text.html).
I have found several impressive images of the region and adjacent areas on NASA APOD:
