PHD help - edit calibration? Dec Backlash?

G'day all,

I'm fairly new at using PHD since it's not really worked for me in the past, until very recently when it's showing some good signs of working.

I'm having a little trouble with Calibration at the moment. My FOV is very wide so large movements are required to show mount direction. My GM8 also have significant backlash. My polar alignment is average. These 3 factors seem to be confusing it.

It seems to not be waiting long enough to do Dec backlash and then seems to only attempt to remove dec backlash in one direction (the first dec direction it tries, north I think).

I can't find a setting to tell it how much dec backlash to soak up before trying to calibrate?

Once calibrated it has RA quite nice but Dec is way off, it shoots off, presumably due to incorrect calibration. If I were in CCDSoft I would solve the problem by editing the calibration settings for Dec to values I know are reasonable.

I can't find access to the calibration settings PHD generates. Is it possible to manually edit the calibration?

Thanks for any assistance ,

Roger.
