I also found as leon has said, a good drift alignment helps a lot. and lowering the frame rate of the cam to 1 or 2 sec helps the system keep up, especially if you are using long USB cables.. usb is not very good over about 5m, however i am managing to guide from 15m away so it is definitely possible.

Best of luck

It could be polar alignment....I have marks where I plonk down the tripod, but I suppose the mount itself could have moved - I have kids who like to fiddle with stuff!

I am going to try tonight if there is a small hole in the clouds to just get a graph of the mount tracking, not guiding, and see whether it looks mechanical..

Thanks for the suggestions

Adam
