Took the same stack as attempt 5, but manually sorted through the 1700 frames to pick the best ones out.
The following was composed from a stack of about 160 images. By picking the best ones out it's much improved the contrast in the Cassini Division.
150mm TAL 2M reflector with TAL 3x barlow and Toucam Pro II, stacksize 1700 @ 15fps best 160 images stacked. Taken at 2031 UTC on the 5th of April 2006. Seeing conditions 5/10.
