Thanks Ken,
Yes, 4 sec exposures seemed to help on the guide camera, however, PHD and the HEQ5 kept having conniptions, hence some crappy frames mixed in there.
All in all though, it seemed to come out OK. I just didnt enjoy having to debayer, flip, rotate and process 45 separate images before resizing them and creating an animation from them. It was slightly painful.....although now, I know how to create batch macros in Photoshop CS3, its much quicker than before.
Cheers
Chris
