Propeller nebula in Cygnus

The Propeller Nebula seems to have been missed in many catalogs. While seeming relatively bright in widefield images, the fine detail is deceptively hard to bring out.

DWB111, or the “Propeller Nebula” is listed in the DWB catalog, a somewhat lesser-known document developed 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 nebula is also listed as Simeis 57 and MRSL 479.
