When the next clear night arose other commitments meant an early night was expedient so I wasn't able to image into the early hours required at this time of year. I've always found star chains fascinating and had spotted this nice example in Serpens while galaxy hunting. With only short exposures required it made a quick target for the session. Details: 10" f4.3 Newt. 10 x 4 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
