I forgot to ask, is that a cropped image or did you use a barlow?

Great shot! It's cool to see the size of the shadow bigger than the statalite due to distance apart

Hi Don

I use (as Seanie very kindly put it) a Celestron 11 inch SCT with a Losmandy G11 (What Wally Mee calls "The Control Centre") mount. The image was taken with a Phillips ToUCam pro webcam in b/w mode and a IR PASS filter. This filter in only allowing IR thro' cuts down on the blurring effect caused by red green and blue light coming to a different focus (atmospheric refraction or as we call it bad "seeing").

A barge is a dark long atmospheric feature on Jupiter. It is caused by gases (mainly sulpher) rising towards the outer atmosphere.

Dave it's the usual set up f/22 with the Celestron Ultima barlow 640x480
