As the moon moved into the south/southeastern skies, I tried to image this nice spiral galaxy in Ursa Major. However, the weather has not been ideal, as only the first night (04/02) was any good. I could only find a fairly dim guide star (6-10 seconds integration time), and the varying amounts of high clouds caused guiding/field illumination problems on the second two evenings (plus the moon was nearly full). Would like to get one more 'good' night of imaging in, but am posting what I have for now.

Added one more night of 16 subs (lots of moon, poor to average seeing). Will call this object done, as I am at a point of diminishing returns ...
