Just thought I'd bump my original thread to share my latest effort - it's only another Jupiter, taken from last night.
It's actually the result of a ~5sec video (shot afocally at 640x480/30fps, ripped into the corresponding ~150 frames using VirtuaDub and then processed using the best 50 frames in AviStack (just to see what that program is all about, compared to Registax)).

Leaves my first one for dead I think! Hopefully the clouds don't roll in until much later tonight (or atleast until after Saturn and Leo have fully risen) and I'll have another go.
