Last night ~ 11pm ~ I snapped some photo's of Jupiter.

As with the other's posted ( M42 & Comet Lovejoy ) it was hard to get a good focus in the screen of the camera body. I snapped several in an attempt to get the focus as close as possible.

I set the camera ( CANON D20 ) to an ISO of 100, and took this with a 2 second exposure.

From Left - to - Right: Callisto, Ganymede, Io, and Europa -- based on the charts I had at the time.
