Alun,
That’s a neat mod with the smaller motor.
Attached is a pic of my finished mod with the Skywatcher motor.
I tried it out on Sunday night and got double calibration lines l l (don’t have a pic) when I took the drive belt off and focused manually it settled down to give single calibration lines l .
What’s causing this to happen ?
Regards,
