Imaged Saturn last night in the best seeing I have had this apparition but it only lasted for 17 minutes before cloud filled in.
Have some very high res data that I think is of significance. There are two EZ spots in this data, one fainter than the other and neither as bright as the EZ spot I imaged April 25th.
I have measured the positions of both EZ spots, the brighter of them is at L3 51.8 Lat -0.5 the other is at L3 70.5 Lat -2.4
Of further interest is a bright spot in the storm remnant that leads the dark spot, this feature was noted by Bird about a month ago and is very prominent in this data at L3 61.3 Lat +49.5
It appears there must be several EZ spots but to pick up any, other than the very bright one on April 25th, requires very good seeing.
The dark spot on this night was at L3 97.3 Lat +46.2 . The hexagon is extremely well defined in both R & RGB polar projections.
As I write this I am getting ready to capture more data, tonight is looking good at the moment.
Note that the 742 IR data was all captured through ever increasing cloud which is why it is not as hi res as the RGB data.
Thanks for looking
Regards
Trevor
PS; Have also attached 120% resamples of the annotated R channel & RGB images.
Stuart, you wouldn't be too much out of your element in Adelaide given the number of expat Brits living here. However, you would get great weather and clear skies many nights of the year

Thanks very much Stuart, you would be a most welcome addition. I believe there will be a group from the UK, headed up by Damian, coming out to OZ to do some imaging in 2016. With seeing like this, maybe they will join me in Broken Hill.

Thanks very much Dennis, the live feed was spectacular for the 17 minutes it took to capture the 3 RGB data sets that contribute to this RGB image. I have already made multiple copies of the contributing avi's to save for future reference and further processing. Actually I had to come up with a whole new set of processing routines, considerably milder than normal, for this data.

Congratulation Trevor for this optimum work.

Thanks so much Giuseppe, I think it just comes down to the quality of the seeing. All of us could make stunning images from data like this.

Thanks very much Ray, Bird & Paul have been talking about another visit out here, I really do wish they had been here for this, even though it was cut short by cloud. It was a most memorable night, indeed.
The left side of the rings and the planet look like they are misaligned with some ghosting? It only seems to be on the left though....
Is this something that is out of alignment?
I don't mean to be critical, just something I noticed and was curious. (my images are nowhere near this standard)
Cheers
Chris
Thanks very much Chris, the alignment is perfect. The noise you refer to is outside the planet. The Moon was very close to Saturn and the sky very bright which added to the background noise in the data. I could have got rid of it totally with a larger levels adjustment but so long as I have the detail I want on the planet I am happy. I have seen some images elsewhere on another forum where the levels have been adjusted so far that the resultant image looked more like a fridge magnet. Such adjustment also destroy the C ring.

Like Chris, I noticed the artefacts on the left side of the planet and rings too, but I see what you mean - increasing the black point would play havoc with the crepe ring.
I see the artefact in mine, & most other Saturn images around the place so I suspect things like slight miscollimation actually, Trevor. I've never had the moon effect a planet image yet, aside from a slight drop in contrast.
