Hi All,

Imaged Saturn last night in good seeing, the best I have had since April. Have resolved what I believe is a SED's related bright spot at approx +46.6 L3 25.4 and a large cloud feature in the NEB at approx +31.2 L3 347.7.

The SEB cloud feature is best seen in the R channel animation, it is on the Northern edge of the NEB and moves from the CM toward the preceding limb, the bright SED's related feature is obvious. The polar hex is very well resolved.

Was up early this morning to image Jupiter at approx 20 degrees alt, have the GRS and some nice festoons along the Southern edge of the NEB impinging into the EZ. In the animation Ganymede is swinging in behind the planet.

The seeing was poor, lots of flag waving happening but the final results were encouraging, even if only in IR.

Thanks for looking
Regards
Trevor

Beautiful work, Trevor...a late Saturn and an early Jupiter are not easy targets!

Thanks very much Paul M.

Thanks very much Paul, it certainly underlines how Jupiter is far less effected by the quality of the seeing than is Saturn.

Thanks very much Roberto, always enjoy animating data, certainly provides a different perspective.

Thanks very much Michal, this gives me much more confidence of getting some good Jup data this apparition.

Thanks very much Sam, have had a lot of practice eeking out discrete detail on Saturn for Cassini RPWS, of course, its all about the seeing and I was fortunate to get a break in the jetstream for a short time, which I took advantage of with a maximum effort, have only just dispensed with the matches holding my eyelids open. This was the first time I have had reasonable seeing to capture data with your most excellent ASI120MM and it performed very well. Can't wait to image Jupiter with it in good seeing.

The polar hex looks sharper than ever even though Saturn is nearly a billion miles away. Your Saturn season has spanned the better part of a year and produced more memorable results than I can count. Good going Trevor!

Thanks very much Matt, only had a brief window of opportunity for Jupiter between when it was high enough to get better than abysmal data and before the actual Sunrise, so ending up with enough data for an animation was rather pleasing.

Thanks very much Frank, certainly pleased to resolve the SED's storm and the NEB cloud feature was a bonus,

Thanks very much Pete. I am co-author of a Saturn paper being presented at the 2013 EPSC (European Planetary Science Congress)at University College in London Sept 8th - 13th. Our abstract was submitted weeks ago but we are still working on our poster and this polar hex data tops of very nicely my 2013 efforts. Just checked over on PVOL and my Aug 24th data brings my contribution for this apparition up to 295 Saturn data sets with 278 since Jan 1st 2013. Of course all of that data has also gone to the B.A.A, ALPO and the professional groups I collaborate with.

Trevor, excellent image set! Your Saturn details this late in the season are crazy good. The hex is so clearly defined. The Jupiter moon animation is icing on the cake. Thanks for sharing your awesome work.

Regards,
Steve

Thanks very much Steve, the relief from the jetstream was certainly very welcome.

Thanks very much qw.

Thought some might be interested in my latest imaging setup so have attached a couple of images

1) My modified DMK fitted 8 x 50 finderscope, ordinary 8 x 50 finder & Telrad. My old faithful JMI MotoFocus with cable remote, new Seibert Optics 3 x modular Barlow & ZWO ASI120MM camera.

2)The temperature of, from the left, the rear of my primary, the edge of my primary & the ambient.

3)My light shielded hutch with 23" HD flat screen which is fed via a powered DVI splitter from my desktop down stairs which runs another 24" HD flat screen. On top is a light shielded laptop which runs the DMK in the 8 x 50 finder.

Trevor, great work yet again! I see you labled your collimation axis' too. I used colors (https://plus.google....sts/abxoz3vR1cj) and they don't show up so well in red lighted headlamps! :)

Great looking setup you have there Trevor! Those Saturn images are very impressive. And the Jupiter animation is nice too! Hope your jetstream continues to stay away.
