NGC 6914, IC 1318A, LDN 895 & DWB 111
The above image was awarded AAPOD2 on 1st July 2021
The above image is a crop (& rotated) section from the original image below. I also controlled the stars more to better bring out the nebulosity. I think it makes for a better image than the 1st attempt. (Click on image to enlarge)

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.

Image shows Propeller Nebula on lower left and the dark structures of NGC 6914 above & right of centre.
The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the centre of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula (not shown in this image). It contains many dark nebulae in addition to the emission diffuse nebulae.
