Hi guys, finally found some time to give it a go at my February data on M81/82. Saw a pic recently that had incorporated NGC3077, which I had never heard of before. Thought it adds to the usual combi. Oh, and the supernova is as well still visible. Hope you like it.
Successful night out last night, no technical problems except a complete restart due to TightVNC locking nearly all applications after the first ten exposures! Now removing and installing TeamViewer instead. Good transparancy, minimal light pollution and no appreciable moon until nearly midnight (clouds were rolling in then anyway).
