Another Sharpless in Orion

With the moon becoming a factor again the opportunities for any serious imaging of the winter constellations from my location are now disappearing. A clear spell allowed me to get 7 subs of another nebula from the Sharpless catalogue before cloud returned. Known as "The Lowers Nebula" Sh2-261 is a large and fairly dim emission nebula high in Orion and quite close to IC 2162 which I recently imaged. Moonlight prevented the subs being very deep and I had to push the processing quite hard to reveal the brighter central area. A target more suited to the apo perhaps but some better conditions required to reveal its true size. Details: 10" f4.3 Newt. 7x 10 minute exposures @ iso1600 with CLS in DSS, CS2 & XAT.
