Oddness in Cygnus

Clear nights seem much like buses....you wait for ever then an abundance arrives. The next clear evening maintained the decent transparency of the previous 2 sessions. Carrying on with the apo I went for the unusual Propeller Nebula (DWB 111) in Cygnus. Little appears to be known about this peculiar emission object regarding its mode of formation or distance from earth. Details: Megrez 88 apo. 15 x 10 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
