And it's not like it takes awhile.  If I hit track, the relays start clicking away immediately.  If I stop it 5 seconds after that, and bring up the focus screen (larger than the tracking screen), I'm lucky if the guide star is still in the view.


Is it possible that your guide speed is set too high? A relay closure of 1 second at 1x sidereal will move the star 15 arc seconds. Typically, the relays will respond to 1/10 second corrections and perhaps faster, so the minimum motion at 1x will be 1.5 arc sec. Have you tried guiding yourself with the buttons just to be sure that the mount actually responds in a controlled manner?
