Hi Erwin
I think you're doing a bit better than I am with Jupiter. I collimated my scope last night and will try again when the clear skies return. Your mono images look quite sharp - a pretty good effort with no motor drive. You're right about the moons vs surface detail. No camera can match the design of the human eye. Maybe the right sort of filter would make a difference, but there are so many to choose from.
I'm slowly learning how to drive Registax. Dave Pretorius from Launceston has given a blow-by-blow description of how he does his Jupiter processing on his website complete with screenshots here:

I think the flexi shaft helped the focus wobbles a bit - maybe 50% improvement? I just wish Synta put a finer pitch on their rack and pinion. Focusing the webcam is much more demanding than for visual.
