I added RGB to my previous luminance of M81. Bloated stars...so I suspect my focus was a bit off. Its always something....

This might help with the star bloat, Vincent:

Both of these are for Photoshop, but the principles apply to other processing programs, too.
Richard Bennion has a presentation on the CCDWare site that analyzes numerically how critical it is to get your focus exact. It turns out that being off just a hair makes a bigger difference than one would expect.
Myself, I get lazy about refocusing after temperature changes.
Your image looks pretty good, as is, though.
