Ok thanks.
I'm using the LX200 Onstep driver. Under motion control there is a guide rate for both RA and DEC but there is no entry box nor set button. Both boxes are set to 1 and can't be changed. Any suggestions? I'm asking because the mount I'm using is on old Celestron fork mount. I've added a dec drive and steppers instead of a synchronous motor on the RA so no recommended guide rate for the mount. So I want to experiment a bit with rates.
