More data... HST this time.
The 'Space Telescope Science Institute' has released the fourth major data release (DR4) for the Hubble Legacy Archive (HLA) and it is now available here.
I found the seperate RGB FITS files for this image of M82 here.
Beware! they are rather large files, 589MB each, so you'll need a fairly fast internet connection.
I converted the FITS files in CS4 using the FITS Liberator plugin for Photoshop provided by ESA, and then reduced their size, they're huge!
I then copied them into an RGB file and just tweaked a few settings like 'shadows and highlights' and levels to bring out the details.
Here's my feeble attempt using my equipment.

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.
