DWB111 - The Propeller Nebula

This unusual looking emission nebula is found in the constellation of Cygnus and lies fairly close to the central star Sadr.

The picture above was taken on the night of 13 June 2014 through a William Optics Megrez 90 telescope with an Atik 460EX mono CCD camera. It consists of 10 x 600s subs with an Ha filter.

The image below is a combination of the above Ha image with one taken using an SII filter (6 x 900s) to produce this bi-colour image.

There is apparently very little OIII so I didn’t attempt to capture any on this occasion.
