I had issues with my Ioptron CEM70 mount and getting good balance, then I realised I needed to make a couple of adjustments, due to poor quality parts on the mint, and balance the mount in 4D, most GEM mounts due to there different design to CEM mounts, only need 3D balancing…
so I put this short video together, hope it helps some people out there….👍🏻
