I haven't been able to successfully guide with my phd2 lately. After first having successful sessions I suddenly have been unable to calibrate after 50 "west" iterations I get a "star not moving enough" warning. Ive tried everything. Ive adjusted steps, re focused, made sure the drivers were downloaded. Ive also tried the old PHD and that doesn't work. Can it be hardware? My mount is a ZEQ 25. could it be a bad wire or connection to mount? PHD2 indicates it is connected.. But the results have been the same. I spent 4 nights this week just working on guiding and results were always the same. any ideas??
