slinky SATURN - Jan27 1 day before opposition

Hi All, had some reasonable seeing on Friday night and snapped off a few shots of the ringed one. The first 3 shots below are from two by 2000 frame sequences, the first two the best 963 frames (one unsharp masked only and one LR deconvolution), the second the best 2175 frames. with 1/10th sec exposure and 10fps gain about 30% with brightness gamma and saturation around 60%. The last one was at 1/20th second with gain up around 50-60% - find this still injects a bit to much grain.

crepe ring is visible in most

Anyway, here they are.

cheers,
