IC1318A, LDN895 & DWB111

Most recognised part of this image is the Propeller Nebula. (This image is a crop from a larger image).
​Commonly known as the propeller nebula the ‘propeller’ shape actually consists of two catalogued parts: DWB 111 & DWB 119.
The DWB catalog was compiled by H. R. Dickel, H. Wendker and J. H. Bieritz cataloging 193 distinct objects as part of their study of H-alpha emission nebula in the Cygnus X region of the sky.
This is part of a much larger complex known as Simeis 57 in Cygnus, discovered in the early 50’s. The distance to the nebula is not known.
