Propeller in Cygnus

Prior to visiting Cepheus I decided to attempt this distinctive area of nebulosity in Cygnus. I had spotted it on a wide-field image and thought it would make an interesting target. Designated as DWB 111 it is referred to as "The Propeller Nebula". Patches of cloud affected some of the earlier subs which were "pinked" as a result though I don't think they made much difference to the final result. Details: 10" f4.3 Newt. 20x 5 minute exposures @ iso1600 with CLS in DSS, CS2 & XAT.
