It almost looks like a WinJupos "animation" but then I wouldn't have thought Io would appear to move relative to the Jovian background as it does..?!?

Darryl: Nope this was an "old fashioned" animation...just a compilation of 6 frames. The seeing was very consistent that night, which is probably why it might seem a bit winjupos looking.
Paul: Yeah this was done with my normal setup. The C14 and flea3 through the 2x celestron ultima barlow...it was around F29. My OTA is the grey tube C14..non edge.

This first one was from last 7-27-11 at 9:29UT. Composite of red and green light. Again mine is on the right, the nasa jpl simulation is on the left.

One thing, though, for me the see-saw animations are confusing. I wasn't certain whether Io was suppose to be chasing its shadow until I looked again at the date. A subjective thing, but that's my respectful slant on it.
Resolution is mind boggling....indeed, very Voyager like!

You should make an animation of Ganymede, showing the rotation, and also to get a better understanding of the noise levels in the image.
I noticed the second image of Ganymede had a dark ring on the right side, which is a typical diffraction/sharpening artifact for such small targets. Did you process that out in the first image, or how do you deal with this? Did you use the same sharpening methods?
AlanL, the halo is an artifact. Sharpening tends to overshoot these light/dark divisions, but it is also a bit related to diffraction artifacts. A bit of both.

If I get some more time I'll try to make that animation...could be interesting.
