Impressive Mike. Good to see another example of M83's extended halo and loop. With my 8inch newtonian and similar integration I was able to reveal the loop with a heavy stretch, though not with the level of detail and clarity you have in your image (which comes from mountain top seeing/transparency, more aperture, faster optics, mono sensor etc as well as your deft processing). Nicely done.
Have you seen the earlier 1997 Malin and Hadley paper (also cited by Barnes et al 2014) which also mentions M83's extended halo and loop?
