Description

The Propeller Nebula is part of the Cygnus X Complex of nebulosity. It is often referred to as DWB 111 but apparently that designation only covers a part of the propeller. The DWB catalog was made in the 1960s by H. R. Dickel, H. Wendker, and J. H. Bieritz, but already in the 1950s the whole structure had been entered as Simeiz 57 in the Simeiz Catalog of Ha regions by the Crimean Astrophysical Observatory in Simeiz, Ukraine. More about it here: https://cosgrovescosmos.com/projects/dwb111-119-the-propeller-nebula

This is my processing of great data that the Ikarus Observatory has kindly publicly posted (https://ikiobservatory.com/data/DWB111_2020-11-17/). It is a HSO image (so Ha in the red channel and Sii in the green and Oiii in the blue).

Happy New Year everyone!
Göran
