here the final version made of aluminum, powder-coated in yellow.
But it remained with this one copy. The demand was not there, no one wanted to pay the value of the work.
I was considering something like this. I understand that the angle of the "knee" defines the range of usable latitudes. I also saw the version that Lacerta make (also intended for the German market) Though my location in southern Europe makes both models unsuitable.
My issue was about the inherent "springiness" of the set up. It seems to me that you have the weight of the telescope + camera and the weight of the mount and the weight of the counterweights all exerting force on the "knee" joint and the long section from that to the mount. While that should be a constant force, it can't be easy to suppress vibration in that strut.
