Must say that with the run of weather I am having of late for Jupiter I don't want December to end.
Captured Jupiter last night, the seeing for my first data set was superb and it only dropped off a little from data set to data set. I try for about 30 mins between data sets.
The first set was such nice data that I have also attached the individual channels.
Have attached one RGB & 807nm IR data set.
Very pleased with the hi res detail within the SEB, there are many very bright spots within it. There is a quite apparent thin red streak on the northern edge of the NTrZ with a very nice white oval on the southern edge of the NTrZ. Heaps of detail in the EZ and three quite distinct red barges in the NEB. I also note a very nice red oval on the northern edge of the NEB that has a dark red core and a much lighter but very crisp outline, this is well defined in the R, G & IR channels but not the B channel.
Well done Trevor. Stunning images and sooooo much detail. I'm pleased that the weather is cooperating for a change. Long may it continue for you.
Thanks Russ, the last couple of years I have had a very good run with the weather, however, this year on the whole has been most problematic. I hope this run of good seeing is an indication of getting back to more normal patterns.

Thanks very much Greg, the live feed looked brilliant. This was still in twilight, reckon running my Peltier cooler for about 3 hrs previously assisted greatly with the outcome.

It was quite windy up here as well Paul, I think the saving grace was that the local wind was in the same direction as the hi alt winds. That afternoon I was out playing Lawn Bowls and although it was quite windy the sky was just such a deep shade of blue. When it looks like that it generally means good seeing up here.

Thanks very much Bird, the concrete pad by my observatory is just waiting for your next visit.

Thanks very much Mike, it was very nice data, certainly was a pleasure to process, not that it needed much processing.
The red channel is amazingly detailed, it must have warmed your heart to see that on screen when focused. The red ringed oval in NEB is an unusual feature, noticed the 2 very bright spots in the IR SEB. Weather is monsoon rain for me over next month it looks like - Oh Well.

Thanks John, the bright spots in the IR may well be indication of a new wave of activity that will hopefully lead to the completion of the SEB revival.

Thanks Terry, IR is obviously very important to Astronomy in deep sky imaging, Andrea Ghez used it to great effect in her pioneering work on Sag A*(the super massive black hole at the centre of our galaxy). IR is also very useful with the planets. Jup emits more energy that it obsorbs from the Sun so is also an IR target. It is very revealing to blink an RGB & IR data set of Jupiter. In IR some of the visible light detail dissapears while IR high lights detail and structure that is not so apparent in visible light. The IR that I use is 807nm+ so I am accessing part of the spectrum outside the very narrow band of visible light. The 3 red spots, GRS, Oval BA and the LRS in the NNTrZ are very prominent in IR while the red barges in the NEB dissapear in IR. IR picks out the very energetic cells of greatest activity that are driving the SEB revival. It is another tool along with UV and CH4 that are available to planetary imagers. IR also is very beneficial in so far as it is less effected by "our" atmosphere than is visible light. In times of very ordinary seeing the IR can still deliver quite acceptable results.
Sorry for being so long winded. Hope this helps.

Very good. I use the "I" filter regularly when doing photometry but this isn't for "pretty pics". Nice to see the data being used for good cause.
Trevor
very very nice, fantastic pictures with important details and particular behaviours. you give us the possibility to follow these particular jupiter evolutions very interesting in this period.
