Another Cygnus nebula.

This was the fourth attempt at getting a set of subs for this subject as the run of cloudy evenings continues. Any clear spells have been frustratingly brief so it was a bit of a surprise when a few hours of clarity appeared that hadn't been forecast. Transparency varied as I took the subs but most were useable. This patch of nebulosity is close to Deneb in Cygnus (on the opposite side to the Pelican and about the same distance away). It is designated Sharpless2-112 and despite being quite bright it doesn't seem to be imaged much. I continue to try using higher iso with less exposure and more subs. Details: 10" f4.3 Newt. 25x 5 minute exposures @ iso1600 with CLS in DSS, CS2 & XAT.
