Cassini Images Of The Galileans Options

[ugordan]

Has anyone out there experimented with processing the very limited image dataset of Jupiter's icy moons? Most images I found that targeted them specifically are horribly underexposed to the point they look like 4 bit images.
I tried fiddling around with what can be done, below's my poor attempt at color compositing Europa, Ganymede and Callisto images. I took 3 polarized UV and GRN filtered images and stacked them together to reduce noise. I also stacked various IR images except for Europa where only a single red frame existed and, consequently, the red channel is very noisy.
Oh, and then there's the *awful* 2Hz banding problem. It's quite noticeable, even in stacked images. I don't know how to remove it as it's at the point of being random brighter pixels (severe underexposure) rather than a brightness gradient...

Here's what I came up, the images are magnified 3x:


BTW, I was wondering whether we could open a dedicated thread to posting Cassini processed images from the PDS (be them Jupiter or Saturn ones), there's really a *lot* of material that could provide.. well, very pretty images if nothing else
Sort of like that "processing of the historical imagery" thread...

Does that sound like a bad idea, is anyone interested?

Here is the processed Carina Nebula:

Cassinis Carina Nebula:


--- Cassini briefly turned its gaze from Saturn and its rings and moons to marvel at the Carina Nebula, a brilliant region 8,000 light years from our solar system and more than 200 light years across. Nearly every point of light in this image is a star in our galaxy, the Milky Way.

The nebula is a region of gas and dust made to glow by the ultraviolet light bursting from bright, hot and extremely massive young stars within. Darker regions in the scene are not devoid of stars; rather, they are areas where dense clouds of dust block the light from background stars.

This image and others like it are taken by the spacecraft from time to time for calibration purposes. Calibration images rarely contain such incredible sights. This one affirms Cassini's position as the farthest, working astronomical observatory ever established around our sun -- our eyes on the cosmos, a billion miles from Earth.

The image was taken using the Cassini wide-angle camera on May 14, 2005. The view is a 68-second, clear-filter exposure. ---

I'm wondering if the "sudden" public release of this pic has anything to do with it being dug up here first a while ago?
After all, it was taken over a year and a half ago, maybe we reminded someone out there the pic (two, actually) existed in the first place

EDIT: Unless they took another set in May this year, I think they're mistaken on the year - it was 2004 not 2005, the former images are already on the PDS, which is where I got them.
