Although the moon is just past full it is quite low down and late rising so a clear(ish) sky tempted me to try for another galaxy before the nebulous targets of the summer sky replace the more distant realms of spring. NGC 5585 is in Ursa Major and part of the M 101 group. It is irregular and described as "flocculent" due to its broken appearance. The transparency was mediocre and the moon increasingly affected the subs as I took them so poor conditions for such a relatively faint target. Not a very exciting result so another one to try again in a better sky. Details: 10" f4.3 Newt. 14x 8minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.19.5.11
