Thanks Mitch but the most interesting thing I nearly missed. Only picked it up after I uploaded my data. Have a look at the first IR image, there is a tiny but quite bright spot close to the CM but far South, on the edge of the polar region. It is easily seen in the IR animation, have measured it to be at L3 318.9 Lat +67.4, it can be seen in the IR maps when you know where to look and is well seen in the IR map animation. In all the years I have been imaging Saturn for Cassini RPWS I have not seen a feature like that so close to the polar region.

Thanks Stuart, certainly a lot happening in the animations.

Thanks Michal, appreciate your comment.

Thanks Tim, I believe the dark spot is a long lived feature, reckon I have imaged it previously. There has been conjecture that SED's associated with The Great Storm may have produced some carbon and that it could possibly in relatively significant volume, I guess more analysis with the suite of instruments on Cassini may help determine that.

Thanks Paul M. and congratulation also on your latest Saturn images.

Thanks Paul for you kind words.

Thanks Pete, toward the end of this imaging session Saturn had exceeded 70 degrees alt which obviously helps considerably.

Thanks so much Steve, although I still have not had, what I would call good seeing, I was quite pleased with this result.

Thanks Lars, when I was walking down to my observatory the stars all looked quite steady and I had high expectations, the reality when looking at the live feed to my computer screen was a little different, very fast seeing but it still produced an acceptable result.

Thanks Frank, large aperture, quality optics, high alt and reasonable seeing means good results. When I do get some good seeing I have very high expectations of the data it will produce.

Thanks Freddy, hope your relocation is going well.

Thanks Graeme, reckon Saturn is so high now you should get a great look at it even down in Tassie.

Trevor how did you do the north poler animation so that the planet rotates but the "segment" stays static? I can only animate the segment increasing in size with the planet static.

Beautiful set of images. I would say you nailed the polar hexagon and the vortex. Amazing.

Hi Stuart, have sent off a PM, probably a bit too extensive to add here, it ran to over a page on my word processor, hope it answers your question.

Thanks David, I only used 40% of the data for each channel but reckon it came up ok.
