I had noticed that some images of M 13 in Hercules revealed a very small galaxy on its extremity. A bit of research identified it as PGC 2085077. Last night cleared quite late and became reasonably transparent so I thought it worth attempting a deep image of M 13 to see if I could capture this galaxy myself. A troublefree session produced a set of 10 minute subs and I was rewarded with success (but only just!). PGC 2085077 can be glimpsed near top centre of the image. Details: 10" f4.3 Newt. 10x 10 minute exposures @ iso800 with CLS in DSS, CS2 & XAT.17.5.10
