Jupiter July 16th in good seeing

[Quark]

Hi All,
Captured Jupiter July 16th in good seeing over a 2 hr session.
Captured RGB & IR data at approx 15 min intervals.

Have attached a link to a hi res IR 807nm animation that I posted on my website. NOTE: it is a large file just under 2 MB.

Have attached 3 RGB's & 3 IR 807nm images. I have a considerable body of data, have been processing for 2 days and still have not finished. Europa is in these images, I need to reprocess all of my data with an alignment done on Europa.

Thanks for looking
Regards
Trevor

Excellent images Trevor.

[alphajuno]

Excellent shots. A lot of subtle detail - especially considering how far away Jupiter still is!

:eyepop: Now that's lookin the goods.
Great result Trevor:thumbsup:

Hi Trevor

The animation was a real treat to watch – thanks! The image scale and the details are quite astonishing, something one would expect from a space mission fly-by!

It looks like you might need an assistant to process all that data; so much data and not enough hours in the day!

The RGB frames look stunning. Do you no longer bother with acquiring Luminance frames?

Cheers

Dennis

Nice work Trevor.

[Lester]

Fantastic, Jaw dropping images Trevor. Do you need a faster computer to do the processing? Or have you got one with 8Gig of Ram?

Thanks for the views.

Thanks Trev, Jupiter continues to change every time I see new images... the rifts in the NEB look great.

cheers, Bird

[Quark]

Thanks Michaell.



Thanks Dave, just under 800 million km from my backyard.



Thanks Clayton



Thanks very much Dennis, have never used a luminance channel with my Jup images. I resized these to 120% of the original, still looks ok.
I have 40 Gb of data from this one morning, but it was a top morning.



Thanks Paul



Thanks Lester, I have a Toshiba core 2 duo @ 2.5GHz + 2.5 GHz with 4 Gb of RAM but the Flea3 captures a massive amount of data very quickly. I dump the data directly from the camera onto a 1Tb external drive. These RGB's have 2000 frames stacked per channel.



Thanks Bird, yes certainly some amazing structure in the NEB.

Spectacular images Trev. I like the colour ones best.

[Quark]

Thanks David, have just finished reprocessing a few data sets with Europa aligned.

[DavidU]

Super ! My hat's off to you Trev. wonderful.

[Lester]

Those images are HUGE, and so full of detail. Makes me wonder could you have captured even smaller moons of Jupiter transiting across with that resolution?

[Shiraz]

stunning images Trevor. thanks for sharing them

[Quark]

Lester, these images have been resized to 120% of the original. For these captures I had 2400 frames per channel and they looked so good I probably could have stacked the lot but I showed a bit of restraint and only stacked 2000 per channel. There was very little post stacking processing involved, but I resized to 120% before doing that. I thought they still looked ok so left them at 120%.
Given good seeing I reckon there is scope to capture smaller moons, for sure.

[Quark]

Just thought I would add one of my RGB's at the original size for comparison Lester.

[Quark]

Thanks for your generous comment Ray.

[Troy]

Good detail Trevor, on planet and moon. :thumbsup:

[StephenM]

Another great set of images Trevor! Nice work.

Cheers,
Stephen

[Quark]

Thanks Troy.



Thanks Stephen, it all comes down to the quality of the seeing.

Great work Trevor. I'm not up with tri-imaging but is it possible to RGB align Jupiter a bit better? I think from memory it's a bit harder to align seperate RGB than standard colour shots?

Tremendous work & I think I'm going to move to Broken Hill for the seeing, you lucky devil!;):D

[Quark]

Thanks John, no, in this instance the 3 channels are aligned correctly.
I used the small white ovals on the edge of the STrZ to do the alignment, that means that the limb will not be aligned due to the rotation that occurred over the period of the 3 x 45 sec captures, but hopefully, the detail that JUPOS and the BAA are interested in and want to measure will be crisp and not smeared due to the alignment being on a planetary feature and not the limb. That detail looks very crisp to me.

Out here at the Hill I had a most excellent run with the seeing in 2008 & 2009, things have not been so good this year but I have still been able to put together quite a large body of work for Mars, Saturn & Jupiter but just not to the same extent of the last couple of years.

Beautiful images Trevor!,just so wonderful to view these,Thank you for sharing.

I enjoy it a lot when this great planet comes into evening skies,It feels so long since I have viewed it through the scope.

Cheers Chris

Hi Trevor,
These are fantastic images of a quality which we will never reach in Holland (down under for you :)). I am curious how many frames you collected and how many were stacked.

I myself bought a Flea3 this week and am struggling finding the best capture software and with the settings. E.g. at what gain do you work and at which gamma and exposure time?
Regards, John

[Quark]

Thanks Chris, it should get a lot better over the next couple of months.

[Quark]

Thanks for your most generous comments John.

I use FireCapture.

With FireCapture as you adjust the exposure the frame rate is automatically adjusted to match. I adjust the exposure to give me just over 50 fps. I then adjust the gain to fill my histo to 80%.

I never use gamma, in fact I turn it off.

For these images the seeing was good enough to stack 2000 frames per channel.

As for specific settings they will be dependent on the aperture of your scope, mine is 16" F 4.5
