Thanks guys. Was good to do some imaging...even if the conditions were not favourable.
Mike - I know

I thought about getting the DMK, filter wheel and associated guff out, but just couldn't get inspired. The seeing was so naff I couldn't bring myself to go through the whole RGB capture and process routine.
Them's the breaks.
I use the ToUcam to gauge the seeing and determine whether it's worth the extra hassle of setting up the DMK. It wasn't.
BTW, I read on the DMK user group site you're using a new codec with your DMK?
Alex - from memory, I believe I stacked around 300.
