Can someone tell me what I saw?

First off, this is my first attempt at imaging, so I used the "hold the camera up to the eyepiece method", and it's only one frame, so don't kill me.

I went out tonight to look at the triple transit, and I thought I saw quadruple shadows. There are two on the NEB and two on east and west nothern "horizon" (look for the dark divots).

Thoughts (other than giving up imaging)?

Sorry about the lack of croping. P-chop just crashed for me.

If you saw 4 black "dots" they were Ganymede, Ganymede's shadow, Callisto's shadow and Io's shadow.

Dannon,

You caught the very rare Triple transit on Jupiter. Three of the dots are moon shadows and the 4th is the moon Ganymede. Lots of us were trying to get decent images of it and most, like me, had terrible seeing. Nice way to break into digital imaging, huh?? smile The next triple transit won't happen until 2013.
