After NGC 4559 the following evening was also clear with good transparency. As a change from NGCs I found a Messier galaxy that I hadn't previously imaged. It is M 99 in Coma Berenices. At a distance of 50 million light years it has accounted for 3 supernovae. Details: 10" f4.3 Newt. 15 x 10 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
