On the Friday 1st April, Bob Trevan, Dave Shave-Wall and myself started out on an imaging Messier Marathon. Dave's results can be seen here:

and Bob's can be seen on Flicker:

My images have been cropped, but have been resized to 1/2, 1/3 or 1/4 (1, 2 or 3xbinning) (see middle column), allowing you to see the relative sizes of the objects. I have removed the background gradient (when necessary) but have not applied any other processing (except for a simple stretch). I imaged 85 out of the 109 objects.
