It seemed a long wait for the next imaging opportunity with a long run of cloudy nights. Meanwhile the moon had ceased to be a factor so the hunt for galaxies could resume once more. After a day of typical April showers the atmosphere was very clear with good transparency. Although I stuck with 10 minute subs the transparency later in the evening would have allowed longer exposures. This time I went for spiral galaxy NGC 4559 in Coma Berenices. Details: 10" f4.3 Newt. 15 x 10 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.11.4.12
