Don't see much astrophotography here so thought I'd share.

Taken with a 8" f/10 scope with a 2.5x powermate (like a
teleconvertor) giving it an equivalent focal length of around
5000mm. Camera was a DBK21 CCD camera.

The dark spot is the shadow of one of the moons, and you can just
make out the Great Red Spot at the top.

All up I'm pretty happy with it. Suspect the scope needs some
tweaking of the collimation which should give a sharper image.
Will have to try that next time, haven't done it before.Nice one, Troy.

Beats my webcam-through-ETX attempt (of ten years ago):

Since yours is 2500 stacked images, how come the moon is a dot, not a line?
