Beleive it or not I have watched them a long time ago. David Craig . There are 3 vids if it's the ones u refer to. It was annoying when they showed unpacking a brand new 1.8 CM WITH ITS CM polar mount but then not actually installing it. That would have been golden viewing for me. The rest of the videos showed 1.8 CMs on Jaeger 1224 motors. The last video shows a 1.8 CM being fitted 2 stories up on the narrow roof side of a house on a 1224 motor. I would be very paranoid about that. I Wonder if it survives to this day.
I think I managed to get my pole level. The flat part of polar mount was spot on on the spirit level but I was struggling with arc still
I think my polar mount elevation angle is wrong but I have set it to my latitude which is what
@nelson_b has done and his arc is good.
Bit baffled by it
