Another Cygnus Sharpless

Although the moon is now past first quarter its low elevation makes the brightness less of a problem to imaging so with an unexpected clear sky I targeted Sh2-104 which lies in central Cygnus not far from The Crescent Nebula. It is described as "About 450 solar masses of gas forming a shell around the ionising O6V star in this HII region located in the outer galaxy". Of note is the intensely red star to its upper right. With wind blowing throughout much of the session transparency remained good. Details: 10" f4.3 Newt. 17x 8minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
