I recently got an Orion Star Shoot Autoguider for imaging with a TeleVue 101 combined with an 80 mm refractor as guide scope, both mounted on a Losmandy G-11. For the most part this set up works very well. Occasionally, however, while calibrating on a guide star, the PDH guide software will run for about a minute and then warn: Calibration Failed - star did not move enough.
Does anyone know what this means since nothing on the mount has changed other than targeting another object? Thanks.
