Galileo Imagery, I couldn't find a topic not specific to one moon.... Options

Here is a combination of all of Galileo's global color views of the Galileans. I have left out the large Europa mosaic because much of its color data is pulled from other orbits. I have also left out colorized views. Due to inconsistent filter selection, there some variation between images. I posted the Europa set in another thread, but I figured I would add the views of Ganymede and Callisto.

Cassini at Iapetus was moving very slowly, but Galileo at Io was moving very fast, so motion blur was a problem and compensation more difficult. And the long exposure would result in really bad radiation effects on the image.

True, but Io also receives much more jupitershine being much closer to Jupiter (which in turn receives more sunlight) than Iapetus is to Saturn so that tends to cancel out greater flyby speeds somewhat.

In these images, compression was not the worst problem. It was a horrible amount of noise.
