M81 & M82 7th March 2010

Widefield view taken with my Takahashi. NGC 2976 & NGC 3077 are also in the frame, bottom and top right.

Yet another version below of M81 taken the other night (prime focus C9.25), with better gradient removal.
Tip; the background black should never be 0 in ANY of the RGB channels in Phototshop or whatever you use. See below.
