I don't see anything bad in your video. After the west steps (usually 12 on default settings) the east steps are quite abrupt and fast, in just three should get the star to the original position.? Then it starts clearing backlash steps at which your video ends. Can you provide the calibration plot ?? More important, after calibration is there any warnings from PHD2 ? And last but not least, how is your guiding ??
