Thanks guys.
The one thing I noticed in reprocessing this one was the extra detail I got out of ganymede. In my original sequence of this session, ganymede was a nice disc but didn't have the albedo features. I think I just ran it through registax last time and didn't do any LR deconvolution on it, which I did this time.
I'm really happy to see the crescent of ganymede as the shadow of Jupiter obscures it, and how it comes out from behind to reveal the whole disc. And with Io looking 3D as it transits, it really makes it look like a 3D world out there.. which it is!
I was more careful this time in colour matching the individual images and aligning them for the animation. It's still not perfect but it's better than it was.
