Into Ursa Major

After imaging the pair of galaxies in Leo Minor I moved into Ursa Major for NGC 4051. By now the moon was out of the sky and the transparency was the best I had seen for some time allowing some 10 minute subs and a late finishing session. This galaxy is much studied due to its highly energetic and variable emissions. Details: 10" f4.3 Newt. 15 x 10 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
