SNR G082.2+05.3
There are many types of interesting and overlapping nebulae in this region including many HII regions catalogued by Dickel, Wendker, and Bieritz, as well as the giant supernova remnant known as G 82.2+5.3 which takes up the left side of the image. Only recently discovered because it is so faint; 20 hours of exposure via the OIII filter here barely shows it.
DWB 111, also known as the Propeller Nebula (in the lower right quadrant) is a hydrogen-alpha emission nebula. The propeller shape is actually a small portion of a much larger emission nebula, which can be seen as red hydrogen-alpha background nebulosity throughout the image frame. The distance to the nebula is not known.
PM1-320 is a small planetary nebula, close to DWB 111 and seen here in the upper right quadrant.
It was discovered by Andrea Preite-Martinez in the 1980s.
