Thanks Paul and Robby
I've had the mount for about eight years and has never tracked very well .
I did a drift alignment so that should be ok and the drift is in RA only . I'm carefull with the balance issue.
I use an argo navis with it and usualy gets things on the ST2000 chip.
Next full moon I may check everything again but it just seems to be made for a planet that revolves a couple of min's faster than ours
( I may have to move there )
Also I tried training PEC with the ST2000's auto guider to see what that would do but seemed to make things worse.
I appreciate your help with this .
