Paul, I get movement between subs and always thought it was due to usb traffic stopping while images where downloading. I made an animated gif of 10 x 10minutes subs from last week. If it's clear tonight I'll guide with another pc to prove my usb theory. However you seem to have a lot more movement than me and I'm using the eq6 at the moment.
[edit]
Doesn't look good for tonight. Looks a lot like rain clouds out there
