I didn't find too many images of M56 here. Probably overshadowed by neighboring M57, or just other, bigger, globs. I think the 8' size is a good match for the focal length and sensor size. Image and details are here:

Processing globulars is "different", so any hints would be most appreciated.

Charlie,
Nice M56. I think it's size discourages many images. I see you used adaptive optics for guiding - I think that helps (plus your optical system is as you say - a good match).
