I can remember a time when a planet imager that got a full CD on Saturn was right at the cutting edge but this season has thrown that idea in the recycle bin.

Thoughts?
Certainly agree Asi, this apparition, even in not great seeing the full CD has not really been an issue. Reckon the ring opening relative to Earth has helped with that but in my opinion a major contributing factor has been the superior performance in stacking of Emil's AS 2 over R6.

I think it has come to the point where the final processed image isn't really indicative of the average quality of the seeing over the duration of the capture. It is certainly possible to produce a quite reasonable result in less than great variable seeing. As long as there were moments of stability in the data then a result that belies the overall quality of the data is possible.

Also, the general proliferation of cameras with more sensitive CCD's operating at higher frame rates has obviously made life easier for planetary imagers.
