That's a pretty good image Rob, you've captured nice detail and colour. Just watch your black clipping in post processing, with over 7hrs of data on this object, I would have expected it to reveal the halo around this galaxy that's seen on many deep shots of M83. You do, however, have a strange halo that extends out in the background around the galaxy, not sure if this was done by work to enhance the galaxy or maybe your Flats didn't calibrate correctly. These are minor issues and don't take away from it being a really fine shot taken with a DSLR. Nice job!
