Jupiter Nov 4th in "Good" seeing

[Quark (Trevor)]

Hi All,

Imaged Jupiter last night in some very nice seeing, even warranted using the "G" word as a description.
Have attached 2 RGB's and 2 807nm IR images.

I rate the seeing based on the live feed from my CCD and last night the first of my IR images was the best IR data I have ever captured. The 2 processed IR images that I have attached don't look that different in quality but the data from the first was exceptional, I was able to stack 1400 of the available 1550 frames, actually, I probably could have stacked the lot.

The data for these RGB's was very nice. Of late in reasonable seeing I have been stacking just under half of the 3000 available frames per channel, however for these RGB's I was able to stack at least two thirds of the 3000 frames for each channel.

Some nice detail in the RGB's, heaps going on the NEB.

Thanks for looking.

Regards
Trevor

Very nice Trevor. I like No.3 the most. And the IR data is very nice, as You say.

Excellent work Trevor - these are super!

[John Hothersall]

The IR's are just amazing especially detail in and around the GRS, if you can stack the majority with an excellent reference frame you've had a good night.

Cracker images Trevor!

Excellent images Trevor. The extra detail is awsome.

[Lester]

Wow, wonderful detail in your images Trevor, thanks again for the views. From my memory I'd say these would be up with your best. Well deserved too.

Thanks Clayton, good seeing has been pretty scarce this year so I am pretty pleased to have it coincide with oval BA & the GRS.

Thanks John, I reckon only people that image in the IR would appreciate the quality of the data. As you would know, often it is not until you process the data that you find out if it was good or not but on this night the detail that was visible in the live feed was incredible.

Thanks Michaell, I think, going by the law of averages, that I was overdue for a good night.

Thanks very much Lester, it was quite a change for me, of late I have been scratching around trying to find enough frames to stack for a reasonable result but with this data the problem was deciding what frames not to stack.

Hey they are excellent Trevor, the detail is amazing, nice work.

Once my new fast 12" astrograph arrives and is (hopefully) plugging away and our dollar stays strong... I think my next purchases may be an affordable mount and planet camera to use with the Starfire ..I think I like the idea of only needing small windows to shoot the same object over and over and cloud weather being less of an issue...seeing will become moe of a frustrator than it already is though

Good pictures Trevor.
I like the colours

Nice work Trevor. Some very faint detail visible in the center of the GRS too. Seeing looks better than anything I have seen this year.

Thanks very much Mike, I think you would enjoy the challenge of hi res planetary imaging. The quality of the seeing, focus and collimation become extremely critical to the result. The rate of rotation of the gas giants means that from one night to the next you are presented with a different face to image. There are lightning storms to track down on Saturn while the atmosphere of Jupiter is just so dynamic. Differential rotation that occurs on Jup and Saturn means that hi res images can actually track the movement of various storm cells and cloud features over periods of days, weeks etc. With the rotation rate of Mars being quite similar to that of Earth it takes about 31 days to get enough data to create a animation of a complete rotation, you can image clouds over the various volcanoes and also dust storms as they form and dissipate along with the seasonal changes of the ice caps at the poles.

Thanks very much Paul, the difference in the quality of the IR live feed was the thing that most surprised me. Normally in ordinary seeing the IR usually produces a good result but due to the near max gain ( to get a nice histo at about 90%) the live feed tends to be quite grainy and it is not until the data is processed that I know if it is good or not. On this night the most striking thing was the quality of the live IR feed for my first IR capture, the detail was outstanding, it looked more like a good R channel live feed that what I would normally get for IR.

Amazing images Trevor. Thanks for posting.
