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.
Im not sure if selecting the planet is the way the experienced guys do it Bot, but its how I do it as you are only working on the good signal within the planets disc, therefore giving more accurate hystograms on the planet - no real need to streach/process the background much.

Yes, Re : Sharpen, tho I only use PShop, still relevant tactic tho

Select the planet, reduce the selection by 5-10 pixels, depend on scale; Feather by 2 or 3 with the 5 pixel reduction, , , or Feather by 4 -6 with the 10 pixel reduction. anyway, prob an un-orthodox method, but works for me for what I do

Hope this of use . . .
