Jupiter Processing Challenge!

[Space Cowboy]

Attached is a TIFF file of Jupiter from Nov 27th. The image has been stacked and aligned in Registax but not had any wavelet work. Just wondered what kind of magic people could weave on this shot.

[Ibbo!]

I'll be 1st then so those with better techs can pass on their tips

I'm sure much more can be pulled out

All done in PS2

So come on don't be shy

Great raw to work with

Here's my go:

All done in PixInsight. Restoration Filter (Wiener deconvolution) > A Trous Wavelets > Curves > Unsharp Mask. It's nice to have a go with a nice image, thank you

[lukebl]

Can't improve on the above, but what an absolutely stunning image. Here's my version.

[Ju_Cooper]

You can tell it's a cloudy Sunday afternoon

Two more quick tries. First Registax 6 linked wavelets + histogram:

And second AviStack 2 wavelets and histogram:

Not much in it IMHO, but I think Registax edges it

[Telrad]

Outstanding Stuart! I like the renditions too. Excellent!

[DavidDench]

Here is a a quick effort using the wavelets in ImagesPlus

Couldn't resist

Here's mine

Wow great data, you should resample it like 1.8 in Registax.

So easy to over process this data..

Just for the fun of it as I am not a planetary imager at all, I thought I'd see what happened if I applied deep sky techniques on this using just PhotoShop:-

[StuW]

Great idea, would love to try some avi's to see how my processing skills are developing compared to the experts..

Couldn't resist, manual wavelets in Registax 6 then a few tweaks in PS, hue/sat, contrast, unsharp mask and a levels and curves.

[neil phillips]

Tried my usual stuff, not sure i like my effort, the smoother one looks best i think ( bottom ) the top is sharper but more affected.

The reason i rotated was because it affects texture during sharpening. Two slightly different techs tried, Dyadic on one, linear waves on the other, different sliders used on both. Its interesting to see others ideas. I like Episkeys natural nice detail, though its red heavy for sure.

Hey there Freddy and Neil, no-one said anything about upscaling the image.....keep it clean!!!:)

Here's a "quick & dirty" from me Stuart - some nice data you caught there: I like to look at detail like the subtleties you've caught in the GRS and plenty of other areas, which is why I process the way I do: straight-laced as is my preference, and next with a bit of extra saturation for those who like just a dash of this ingredient:).....personally I'm not really into the more saturated stuff, and even though I'm a pro artist by trade I tend to think using more than a dash of saturation borders a little too much towards the painterly as opposed to an actual image.....though I'd better watch out what I say there lest someone says something!

[neil phillips]

Lol D, i upscaled for processing just lost track of the size.

You know theres detail in colour. enhancing it using saturation or contrast or whatever, can often show a lot more detail. But yes it will also be more affected.

pros and cons. its just taste i think. No right or wong way. Nice and white, but subdued and bright here. he he

Either my screen is really WAY too bright or the white clouds look way overbright on those Darryl. I belive its my naff screen.What are others seeing here? The same could be said for deepsky. But colours are often very saturated, by almost everyone. And accepted much more. why i have no idea

[Kokatha man]

I have no idea what others' screens may show Neil (apart from what my partner's pc screen will show if I go and look at it after posting an image).....but I need to keep my screen well calibrated for work useage via color munki.....mind you, I do see a lot of images which are pretty dark on my screens: the standard greyscale etc calibrators will only take you so far.....I'm now running 2 screens (both DVI, via a DVI splitter cable) with one a widescreen HDMI and another "standard" 17" screen to get a better comparative handle.....but trying to second-guess anyone else's screenview - let alone their eyes' perception - would be a mug's game..!:)

[Olorin]

Stuart, what a great idea, and what wonderful results!!! Loved the colors by lukebl, but everybody did great job!

Here is my go, my usual wavelet filter + just a bit unsharp mask in GIMP:

[riklaunim]

Soft and strong processing.

1. Lucy-Richardson deconvolution (0,9/14 for soft, 1,0/16 for strong)

2. level (kill background)

3. auto color balance

4. levels (make it brighter) & gamma

5. noise reduction

In AstraImage and Nebulosity

[Magnum]

For Me Neils version looks best on my imac screen!

[Spikey]

Neil, you are absolutely right I bumped up the red to try and bring out a bit more out of the barges and bands. I've backed it off this time. I only wish this was my data, nice one as always Stuart

[Space Cowboy]

Wow! Great response guys! Some very nice versions there! Neil's version is closest to the ones I did which is quite reassuring for myself lol:

Nowt wrong with upscaling! Thanks for your kind comments fellas this was a dream capture for me.

[Magnum]

Here is my version, just wavelets in registax 4.1 then tweaked saturation, histogram and definition in iphoto.

Lee

[lukebl]

It would be interesting to see all these versions side-by-side for comparison. I'm not going to do it, though!

[rfdesigner]

Just for fun I thought I'd see what IRIS could do with this.

process:

1. 2x scale

2. wavelet

3. RGB split

4. R+G+wavelet => L

5. LRGB combination

6. last little play with wavelet.

7. 0.5x scale.

nice raw data.
