Description

I combined data from my newer 12" GSO f/4 Truss Newtonian with data from my friend Chuck's data using an Explore Scientific 127mm at f/7.5.

DWB 111, also known as the Propeller Nebula is a hydrogen-alpha emission nebula in Cygnus. The propeller shape is actually a small portion of a much larger emission nebula, which can be seen as faint red hydrogen-alpha nebulosity throughout the image frame. The distance to the nebula is not known.
