So I was able to play with some hefty equipment tonight..

Canon EF 800mm F/5.6 + 2x Extender II + 1.4x Extender III on my 5D mark II.

I was after the moon, and nailed a great shot. Then, for pure fun I decided to point the camera to the next closest bright object in the sky. I quickly realized when looking on the screen that I had found Jupiter.

I'm not an astronomer by any means, so randomly finding a planet was incredibly exciting! I also noticed four dots surrounding it - which I assume are its moons!

My problem is, I'm not sure if I've identified the moons correctly!
Image was taken about an hour ago, in Ontario, Canada.

I assume the closest to Jupiter is Io, and Europa is the smallest so I assume it is the dimmest. Callisto and Ganymede are a guess though - I'm not sure where they are in their orbits... hope I'm right!

Can anyone confirm these IDs, or offer help in correcting them? I'm new to all this planet stuff. :)

Here is the moon photo I set out to make, for those curious:

Any help would be greatly appreciated!

Well done.
Jupiters moons (left to right) are Ganymede, Callisto, Io, Europa.

Most planetarium software will show Jupiter's moons. There's some good stuff out there - some of it free.

Thanks very much!

Hollis, I just downloaded Stellarium which confirms Steve's corrections. Thanks to both of you. I'll update my labels. :)
