I've also read 3 to 10 second exposure time is optimum. Personally I find that if I get down to 0.5 second exposures with good brighness then I have a dramatic boost in image quality, I believe that it must start to keep up with some atmospheric distortions - but I am not sure.

Hi Roger
Hmm, sounds like you've almost got the ST7 behaving like an adaptive optics unit! I must give that a try (0.5 secs) with my set up and see how I fare. The fastest guide exposure I have previously used was 2 seconds and it seemed to work okay.
Is your ST7 parallel (like mine) or USB?
Cheers
