Recently discovered a very interesting topic on the Unitron/Polarex facebook-page: https://www.facebook...11333119105234/
Discussed is a very rare (probably a one-off) direct drive motor system on a Polarex 60/900mm Equatorial mount.
It was, given the displayed power (100 volts), a system for Japan only, as in the '50s Japan had a 100 Volts grid.
I've never ever seen a drive system like this, so this is ultra rare indeed!
Somehow I can't link direct to the post, but all the details are in the facebook page topic.
Including excellent detailed pictures.
Has anyone here ever seen this before? Perhaps on the bigger models aswell?
I've never seen any (brochure) documentation about it, but perhaps some Unitron/Polarex experts here can shed some more light on this?
Its surprising how many unearthed details, accessoires, interesting facts and discoveries still surface from time to time....
