On my AS80, there was, including the scope, a quick changer from Zeiss M44 to M44 via a dovetail ring quick connector... love it, it makes a lot of sense with the diagonal from Zeiss.
BUT, I wanted to have the same one for my Telemator, to use my Zeiss diagonal on it too... and indeed, it's close to impossible to find one.
Having said that, there is a machinist in France, about 1h away from home, a small family business called SkyMeca. The owner is specialised in making all kinds of rings and adapter for astro gear purpose, he is very well known on our French astro forums. I did send him a request of feasibility for a duplicate of my Zeiss system, M44x1, dovetail ring. He thinks it's possible, so most likely I will lend him my Zeiss unit and see what he can machine, and hopefully at a good price.
Here is what it looks like, the original. Hopefully SkyMeca can make me another one, I will sure let you know here.
