My reprocess of Dennis' 4th Feb Jupiter

[iceman]

Thanks to Dennis, I got the opportunity to reprocess one of his avi's from his magic Jupiter morning on the 4th February.

The raw frames are exsquisite.. hardly any sharpening is required .. unbelievable seeing.

In the attachment below, Dennis' original is on the left, my reprocess is on the right, and I did a 1.5x reprocess as well, which is underneath.

My version hasn't really made too much difference from the original because the seeing was so good and so little sharpening is required. My processing routines appears to help most when the seeing is less than "unbelievable".

Thanks for the opportunity to process this avi Dennis - while watching it chug through registax I was soooo jealous that this wasn't my data :)

Comments welcome.

All are beautiful- amazing how well it stands up to 1.5x.

I can see pluses and minuses with your reprocess Mike, contrast and colour is certainly more vivid but it comes as a price on the "fineness" of the detail - the white storms toward top and white patches in the equatorial bands have more distinct edges but are also larger in size... the endless compromise and I guess it all comes down to personal taste.

great stuff all round:)

great re-processing on a great set of captured data!!

yay mike and dennis!

Top stuff mate. I'm probably wrong here, but is that a polar cap I spy on Jupiters moon!?

[Dennis]

Very nice Mike, a definite improvement in my view, as I can now see more detail, especially the blue festoon near the limb, as well as other detail very close to the limb.

Did you apply any special processes or techniques to bring out this previously hidden data?

Thanks for the collaborative effort in helping improve these images. I particularly like the appearance of Ganymede in the x1.5 image.

Cheers

Dennis

I missed that, but yes Mike's definitely brings out the blue festoon near the limb that's practically invisible in your original Dennis - another plus!:)

is that surface detail on that moon?

great shot and processing mike and dennis :)

Sorry Dennis, forgot to reply to this.

I didn't use any special technique, but used my normal (lengthy) processing routine.

- Split your avi into individual BMP files
- Use ppmcentre to crop, centre and sort by quality
- Use netpbm tools to split each bmp into R/G/B bmp's.
- Use registax to align/stack each set of R/G/B bmp's, into a "master red", "master green" and "master blue". I used mild wavelets (#3 - 10, #4 - 15) here.
- Opened each "master" in AstraImage.
- On each master, convert to greyscale, Maximum, LR deconvolution
- RGB combine (combine the R/G/B images back into a colour image)
- Gamma adjust and light USM

Because the original raw frames were so sharp already, the LR deconvolution brought out a quite hard edge, so in photoshop I made a selection of just the inside of the planet, inverted it onto a new layer and did a 1 pixel radius guassian blur to soften it.

That's it!

Fantastic job Mike, and well done Dennis.

:)

Thanks for the update Mike - a lot of hard work but certainly made a big difference.

Cheers
