I think it is the sharpening - it brings out the details, but has that effect at the edge. I just ran through some processing a couple of times and saw the halo effect build up more as the sharpening got more aggressive.
I didn't select anything during wavelets or processing in Gimp, so maybe that's something I should do? Would it mean I select the disc of Jupiter, maybe with a small gap to the edge, and sharpen only within? I'm not sure how to do that in Registax (or even if it's possible), but selection in Gimp should be fairly straigtforward.
