This one has a bit more detail I think due to smarter normalization of my various sets. Please ignore the corners, I've been working through figuring out how to process detail out of the galaxy, and I'm getting a bit bored of grafting corners onto the image.

Looks out of focus. In the core of M101 you should record 4 stars with your 8" refractor. Do you monitor your air temperature and adjust focus accordingly? If not, then I sugggest that you check focus between every exposure. A Bahtinov mask will aid you greatly.
