The shift is most noticable around the south polar region and also the width of the cassini division is getting smaller?. I'm currently working on th full 886 bmps that I took that night (unfortuneatly Regi can't cope with that amunt) so I have to do 2 seperate runs of 443. I'll post it when it's complete but it it looks like it's shwoing much more detail. Unfortuneately the seeing was fairly wobbly that night so fine detail is fairly space.
I've noticed that foggy nights seem to be very good for imaging planets. Fog can only form when the atmosphere is relatively steady, thus great for imaging. ALthough you may not see many if any stars with the naked eye, the planets are plently bright enough for detail to be captured by a telescope and a good quality webcam.
