Imaged Saturn this morning, the seeing was rather fast, typical of the effects of the jetstream but I was able to produce a couple of acceptable images. I have attached 1 742nm IR & 1 RGB data set.
There is an interesting spot in the RGB which I have measured in WinJUPOS to be at approx Lat +48 degrees L3 48 degrees. As my IR was 3 x 3min data sets combined & derotated and the RGB is 4 consecutive data sets over 23 min's combined & derotated, the time between the midpoint of the IR and mid point of the RGB is 21 minutes. I think there is a hint of the spot actually showing up in the IR as well when considering the amount of rotation that would have occurred between the IR & RGB.
Back on Dec 29th 2012 I imaged a similar spot, then it was at approx Lat +46 degrees, L3 39 degrees. Looking at the stated drift rate for that Lat given in WinJUPOS of .370 degrees/d that particular spot would have drifted 9.25 degrees which seems to line up nicely with the spot in this mornings data.
Thanks for looking
Regards
Trevor

Thanks Paul, it really was a most relaxing trip. It would have been good to catch up but as it turned out, the last few days we couldnt wander too far as Cheryl was convalescing after some minor surgery in Adelaide. Saturn really is rising at a pretty amazing rate, reckon ounce this heat wave moves on (it was 40 again today) there should be some better seeing as it get closer to 70 degrees alt.
Thanks Graeme & Laurie.
Thanks Mark, the C14 will do a top job, such scopes have taken many stunning images of the planets.
Thanks Ray, it's nice to still be able to resolve discrete detail so long after the SED's from the great storm have ceased. Currently there is no lighting being detected but I live in hope, who knows what tomorrow might bring.
