I have Celestron CGX mount with a 9.25" SCT scope mounted on it.
I am using a Celestron Off Axis Guider with a ZWO ASI224 camera.
I am trying to use the PHD2 calibration assistant to setup parameters for backlash in my system.
Every time I run the Backlash mode , the guide assistant says my DEC backlash amount is way out of range ( something like 3200?) and cannot compensate properly.
I know I have some minor amount of backlash but I don't think it is that extreme.
I have checked to make sure the Dec drive gearbelt pullies are tight on the shafts.
No belt slipping or binding.
If I ignore PHD2 warnings and run guided, the graph is showing guiding typically
RMS error (px)
RA 1.8 DEC 0.7
Anyone else using PHD2 guiding for a CGX mount see this problem?
