I had another shot at Jupiter last night. With the telescope on the patio, I have a window of about 15-20 minutes when it is visible between two trees. This time I got set up a little earlier and managed two separate imaging samples. The visibility wasn't that great with it low on the horizon, and again it didn't look as good through the LPI webcam as through the lens. I guess the old mark one eyeball still has a useful range and pixel density.
You can see three of the satellites however, so that's a little better.
Also this time I had the settings right so I could post process the images with registax, which I think does a better job than envisage.
I might try a different technique if I get a chance.
