Thanks Brett, second go last night got it guiding for over an hour. Very neat when it ticking away and the stars were oh so round.
My main battle is getting the calibration to work, it auto selects hot pixels and has a big whinge when they don't move. I can't for the life of me see how to dark subtract from the guider's image and only got around it by exposing for 10 sec at 4x4 binning where it'll select a star not the hot pixel.
Regards
Keith
