Thanks everyone for your votes. There is obviously a clear preference for the second image. Even the fact that there is one extra moon visible in the first couldn't swing it!
Not sure why the C-ring is brighter in the second image, and why the Cassini division is clearer around the back of the planet, but certainly the smoothness of the planet clouds is because of less sharpening at the wavelets stage.
Imaging at f/33 with a C11 is a lot more painful -- it's harder to focus, takes longer to get enough frames, and I need to manually adjust the guiding a bit during capture, since the image uses up so much of the frame -- so I think I will have a go at re-processing the f/22 image with a bit more smoothness. If I can get the same result in processing, it will be easier to capture.
Alternatively, I might just need a bigger scope and more sensitive camera!
Thanks,
-Ivan
