Here's a prime focus shot of Jupiter and an unusual configuration of its Galilean satellites that I took last Saturday night using my Canon EOS Digital Rebel DSLR camera and the ASH 14" f/10 Meade LX200GPS SCT. The focus was a bit off but the image illustrates quite well that the Galilean satellites aren't quite as pedestrian in their motions as they often seem to be.

Nice shot, Dave. Don't think I have ever seen them like this. Thanks for posting.

Very nice indeed Dave, Captured a nice positional momment. well done.

Nice pics. I wouldn't have thought the Galilean satellites would appear so far and in that configuration around Jupiter.
Thats one cool image.

Yes, I love to watch them dance around. The outer one, in that image, is Callisto, I think. It gets twice that far away from Jupiter.

That is a great shot.

Thank you very much for posting it.

The inner three Galileans orbit Jupiter in resonance.

For every one orbit the solar system's largest moon Ganymede completes, around Jupiter, ice covered Europa completes two & volcanic Io completes four.

Callisto, the giant outermost cratered Galilean is out of step slightly, but by not much.

Nice image, that is a very interesting configuration of the moons.
