Which of Jupiter's moons did we manage to snap yesterday? More help on the web, from the Sky and Telescope site.
So it's Ganymede further out and Europa closer in, then. Callisto is too close to see in this:

Now, with a following wind, I can convince myself there's a third moon snuggling up to the (now very evidently) over-exposed Jupiter. Also, we can see that the camera lens really is a bit rubbish -- with the red and blue splitting out. But still, pretty good with no (very) special equipment.
