Hi Jim,

Very nice images and an interesting comparison in your two processing efforts. The first image is more natural and accurate version to my eye. The second shows a much wider and blacker Cassini division which is a signal that too much sharpening has been applied to the rings. The disk of saturn, with its low contrast features, is much more tolerant of sharpening that are the very contrasty rings. A technique you might try is to process these two areas separately. You might then be able to draw out the northern latitude storm details without losing the crepe ring and widening the Cassini Division.

just my .02... please take with salt if required!

best,

Alan

Had some time at work to reprocess the data and improve stack alignment such that the multiple bands coalesced into the more accurate wider and familiar bands. The Northern hemisphere storm from December is still with us.
