Its a lot smoother. Try to grade them using Cassini's division to judge and stack only the best grade.

I would suggest an iterative restoration to then sharpen.

Planets respond very well to unsharp masking, and sometimes deconvolution is worth a try. I'm a little leery of deconvolution because it can introduce artifacts if you aren't careful, but if you are careful with it you can follow it up with a light unsharp mask to finish up.
