Hi Folks;

My first jupiter since 2005, as this is the first time it's finally got higher than 30° above the horizon:

Details at the bottom of the image.

It's also the first time I have imaged with the 1280x960 Chameleon USB 2 camera on a scope, all my testing before has been indoors and bench testing. The EXHAD CCD is quite sensitive and I was imaging with 16 ms exposures and no gain at 2 meter focal lengths.

I tried shooting at 5 meter focal lengths, but it just falls apart into a blurry mass. I also had condensation on the corrector plate too (humidity was 85% @ 4°C), so that dimmed and blurred things a bit too.

TTYL..
