Come to think of it, 50 secs cant be right, I have never gone past 20 with an ST80, how long are the red lines?. Is yr guide rate set to 0.5?.
Do the guide star exposures begin and end nicely at the ends of the red lines?.

Here's the thing Fred - when it calibrates, I have a nice red L. When it doesn't, it moves only a few pixels - in x rather than y. Sometimes it won't move at all. I judge this from the x,y co-ordinates after each exposure listed below the "moving telescope" list to the right of the guide screen.
And it does this in the same session in different parts of the sky.
Not sure about the guide rate - will check on the lappy when I get home this evening.
