A very rare bird has just arrived ... Courtesy of Dietmar from Germany, I have just received a shipment containing the Carton 60/910 refractor. Thanks a lot Diddy! This beautiful, elegant telescope, the design of which is definitely ahead of its time, seems to be in pretty good condition. The copy comes from 1976, it is most likely the Carton 619-A model, although the manual signed by Neckermann is silent about it. I have already started cleaning, I have repaired larger paint losses on the tripod, I have cleaned the mount (although I decided not to change the greases because they still seem quite functional). The work progresses quickly and everything would be fine if it wasn't for the lens.
The lens was clearly disassembled. On this occasion, the spacers were damaged. One has survived, and the other two are in a rudimentary form. In such a state, it is not possible to maintain the correct distance between the lenses, perhaps they even touch each other, which is dangerous for the lens. I'll find out soon when I take it apart. I will then be faced with the question of how to recreate the spacers. This is the question I would like to ask my more experienced colleagues. How to make new spacers, so that they do not become a source of scratches on the optics or a habitat of fungi and molds? How to stick them to the surface, and maybe stick them not to the face but to the sides of the lens - even with adhesive tape?
Thanks in advance for any advice. Do you recognize this model? Is it 619-A?
