Hi Matt and others

Thanks for those kind words. The processing was minimal, as the exceptionally good, still, seeing is what has made these images. When I ran the avis through Registax at a 90% Quality setting, they all passed that threshold.

All I did was apply wavelets, mostly as follows:

1 = 25
2 = 12
3 = 5

The images were saved as bmp's then opened in Corel PhotoPaint and saved as jpgs with 20% compression. That's it; no magic, just being in the right place at the right time with a cooled 'scope, recently collimated and with good focus through the JMI motofocus. The seeing almost made the focusing refractor like, in that the point of best focus kind of "snapped in".

K3CCDTools helped too, ‘cos I used the automatic setting to capture a 90 second avi every 2 minutes when the sucker holes got big. Jupiter had hauled himself high up the ecliptic as well, so less atmosphere to image through. But the real success story here is the seeing, as Asimov and others have rightly pointed out.

For me, this is a once every 2 years event – quite rare. Even the individual frames are quite stunning. I’ll be quite interested to see how Mike and Dave get on with the DVDs I’ll be sending them, as their processing techniques and experience are greater than mine.

Cheers

Dennis

As modest as you are, promise me you'll send that image in to the astromags?

We need more poster boys for the 9.25 who aren't based in the Northern Hemisphere

(Let's hope Damian Peach has seen this image) LOL

Damn.....

that's a great image. Fair gave me a woody when I first saw it. Just goes to show what a huge difference the seeing conditions can make. I'm willing to bet that the wee hours of the morning just before dawn are truly the best hours to try and get a moment of viewing like that. But even then, you'd have to be very very lucky...

Well done, I can't see that being beaten anytime soon!

Nice one Asi - looks warmer than the original and with better contrast. Also looks slightly bigger. Even after a long sleep I'm still not over just how good the seeing was. Needless to say, we were clouded out last night.

Cheers

Hi Rochler

As I was watching the image on screen via K3CCDTools, the capture sequences approaching 4:54am, when the skies had turned blue with morning twilight showed some amazing moments of stillness and clarity.

The blue festoons and white ovals were clearly visible and snapped into sharp focus as I watched, enthralled by the Jovian display and humbled by the good fortune to have been so lucky to be out there.

Cheers

Dennis

Nice work Asi.. colours are nice and rich but probably a little overprocessed for my (recent) liking.

Still looks amazing though, i'm amazed every time I see it.

Dennis I don't think your image needs improving, I like it as it is.
I just had a little go to see if I could highlight the details.
Still your image leaves me breathless mate.

Well done once again.

Andrew

Hey Rocket

Well done - I actually prefer your variant. You have really brought out the blue festoons, white ovals and other detail that lies submerged in my original. 10 out of 10 mate!

Cheers

Dennis

i like your reprocess rocket, like dennis said, the blue festoons look great!

this forum is tops, whether you end up taking the video or processing someone elses, the lack of professional jealousy means that we all take so much pride in each others work!!!

Nice job Andrew!! You know...I had my version looking almost identical to yours at one stage in neatimage but decided to back off with an option & posted mine as you see it.

Theres so many ways to reprocess an image that one could spend a long time doing just one & coming up with different versions I believe.

Well done!

Hey Asi and Andrew

Would it be possible for you to explain the additional processing you used to enhance my original Jupiter?

Doesn’t have to be an essay, (unless you have the time), more a bullet point description of the steps and techniques you used.

Thanks

Dennis

For starters, I don't use the normal software like most of the guys here, I just put up with what I have which is picture publisher 8.

But I do have neatimage.

In pic publisher: cropped/resized/adjusted the color saturation/tone balance (high lights, midtones, shadows) stretched detail/hue map adjustment/colour adjustments on blue & red/despeckle/gamma adjustment/unsharp mask & sharpened.

In neatimage: sharpened/noise reduction.

Once again Dennis, a fantastic image! Makes me smile to see images like this coming out of Aussieland.

There are a few other forums you might like to post this on, including the "solar system" astromart forum. I'm sure the imagers there would like to see it, this is far and away the best Jupiter image I've seen so far this season.

Well Dennis I did something similar to what Asi did, but only fewer steps.
In Photoshop I adjusted the colour balance a little - increased the highlight RGB's slightly, mid tones only just moved alittle and shadows where boosted a bit (can't remember the exact amounts).
And used Neat Image with a basic(default) Noise reduction/Sharpen setting.

Thats it.

Reprocesses by Asi and Andrew here are beaut. Rather than one being better than another I find each, including Dennis's originals, highlights a different aspect of detail. All masterpieces - thanks of course to having such an equisitely detailed and varied palette to work with

Nicely, diplomatically and tastefully stated Robert - do you work for the Diplomatic Corps?

Cheers
