Description

Even in Arizona, it's been quite cloudy until recently thus a long period without imaging plus a hard disk crash on my post processing delayed things further. M61 doesn't seem to be imaged much which is too bad as it's quite interesting especially with the other two other galaxies in the field. Note the very distant cluster of galaxies(?) way down in the right-hand corner. Seeing was pretty good for most of the lum subs. From the looks of other images, M61 would benefit from some Ha data but it's getting a little late for that this year. L 35x300s, RGB 20x200s 2x2 bin each.

Description: Version B uses only the best 15 or so luminosity subs as the subs were quite bimodal in their distribution as seeing was either very good or poor. Noise is a bit higher but the stars are smaller.
