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.
