Imaged Saturn July 24th, not because there was any particular feature I am tracking visible, but simply because there was not a cloud in the sky. It has been a long time since I have been able to image with no cloud, the jetstream was still rampant but what the heck.
Have attached 1 R, RGB & 742nm IR data set. Have also attached my latest updated drift chart for the dark oval March to August 2013 using Anthony's & my data.
Have also attached a drift chart for the dark oval, from its berth through to my latest data point, July 22nd 2013. This chart is created from Cassini ISS data (courtesy of Professor K.M. Sayanagi) and data from Anthony and I.
Thanks for looking.
Regards
Trevor

Thanks guys, certainly very few active planetary imagers currently here in OZ, particularly on this forum. Good to see Stefan on-board, he has been a great contributor of data to the JUPOS project over the years.
Nice work Trevor. What software do you use for working out the CM for Saturn? I used Cartes du Ciel in the past but from what I remember it used to give different results to some other software I had, and I never knew which one was right.
Yes I don't get it Trevor. I've thinking about not bothering to post here. There seems to be very little interest in planets & Solar.

Don't think that's entirely correct. I think what has put most people of was that if someone was interested in astrophotography they did the easy bright objects like M42 etc etc and planetary is difficult and an additional expense to use a good camera. Most of us were stuck with a webcam and frustrated with trying to get a half decent image.
But things have changed now with great software like winjupos and Autostakkert combined with the ridiculously cheap ZWO cameras that really perform, people are starting to invest more time and effort. But we would not have if it hadn't been for the likes of you and the great planetary imagers that post on IIS to inspire us.
I know you have done it for me.
Thanks John et al but don't stop posting

Well Allan, I'm a bit peeved off nonetheless mate. I work hard at what I do & it's no easy feat to assemble 12 pane Solar mosaics in particular, only to get 2 or 3 replies...Perhaps the problem is I post too many lol. Well I took early retirement to devote myself to this so if I get a day & a night cloud free then I'm going to post the results. It gets me to thinking though, that perhaps my images are rubbish, you know? When you get next to no feedback, it's a natural thing to start thinking that way. It sounds a bit lame but yes, it's about REPLIES & DISCUSSION - If I didn't want that, I'd be posting the stuff to my own webpage & not in a bloody forum, right? As far as I can see, this is mainly a DSO forum these days which is fine but I see it as just another little problem. Gone are the days of 10 page discussions on planet imaging techniques & camera's etc. Anyway, I've said what I was thinking & now I'll shut the hell up & just keep posting lol.
BTW I'm so glad I have inspired you
Apologies to Trevor here too. I'm not into hijacking as you know.

No need to apologise at all as I know exactly where you are comming from. Quite often I see a great image and note that there have been maybe 150 views and only three replies of "nice image" or words to that effect. Spending every clear night to get out and start imaging either for DSO or planetary is a real dedication that so few are capable of. But as from your post there is real science here that amateurs are capable of enhancing pro studies.
I take my hat off to you and the others and your efforts are worth appreciating. Maybe it's about time that IIS implements a like button or some such.
I'm looking at getting a set of colour filters and holder so that I can do some colour images of Jupiter when it comes around again this year. I must admit that only twice in all my planetary observation (which has been sporadic) that I've had that could be called exceptional viewing, but they are etched into my memory.
Keep at it as there is a good fan base for what you and others do.
Allan
Thanks Laurie, Anita & Stefan.
Stefan I use http://pds-rings.seti.org/tools/ephem2_sat.html to generate my Saturn ephemeris's, it gives me the CMIII which is what the researchers I am involved with want. Of course, you could load your images into WinJUPOS which will give CMI CMII & CMIII for the UTC of the image. I generally download ephemeris's from the link I have included here, for a week or so into the future, so that I know in advance when the features I am tracking will be doable.
