Description

This took a lot more data that I originally expected it to, and I even think I might need a bit more integration time. Overall though I think I'm at the point where I'm fairly satisfied with it, so I figured I would post it.

This is actually cropped down from a much wider image. Originally I wanted to show more of the dust/nebulous regions to the right of M82 and top of M81, but in the end I just liked a closer crop around M81 and M82. Those dusty areas are partly why I think I needed so much integration time (and could certainly use much much more).

Unrelated, but I think the larger resolution image looks a lot better than the version that shows on the main page.
