Jupiter Moons
Last night I just set up the camera on a tripod pointing out the open window and took some shots of Jupiter's moons.
D50 and 300mm & F5.6
I plan to do this every night for a few nights if the weather holds out.
But can somebody tell me why on Wikipedia it tells me Callisto's orbital period is ~16.7 days, but when I open up Stellarium, everytime I move a day forward Callisto does a full revolution around Jupiter?
