Last night a nice transit of Jupiter's moon Io was visible from Europe. The transit of Io (and its shadow) started when Jupiter was still very low in the East, but it rose very quickly. Seeing conditions improved and more details became visible.
It was a very foggy evening in the Netherlands, but Jupiter just peeked through the mist. The tiny black dot of Io's shadow was immediately visible. The moon itself became visible when it moved more to the limb of the planet (due to the edge darkening of Jupiter).
I made a small, quick sketch of the view through my 16" Dobson at 225x. I later enhanced the contrast and colorised it a bit with Photoshop, to match the actual view thhough the eyepiece as much as possible.
(It is one of my first sketches of Jupiter, so I sketched it a bit too small. Next time I'll try to sketch a bigger planet, maybe 4".)

Very striking, Roel. Good detail in the belts and zones. Well done. 
I watched a transit of Europa about one Jupiter rotation after you saw the Io transit. Lots of traffic up there.

Roel,
Beautiful sketch. I saw the pictures of your new 16" inch scope a few days back at the ATM forum. Based on this sketch I'd say you must be very pleased.
