The mount of the Secretan 80mm is cleaned and restored. Works again very smooth. It's very nice to work at such a fine piece of engineering. Don't want to repaint it. It needs to stay natural.
Secretan was one of the finest opticians of France. This a rare box with 6 astronomical and 1 terrestrial eyepiece.
The astronomical eyepices can be used in combination with modern telescopes.
Tested the eyepeices with a modern refractor and they perform exceptionally. I suppose this are orthoscopic eyepieces.
Very rare to find these separately.
This is a complete 81mm Secretan refractor. The alt az has slow motion control on the two axes. This is rather uncommon.
The slow motions are working very smooth. Hard to find a Secretan 81mm with the complete alt az mount.
In the 1930 telescope catalogue it is mentioned as a additional option.
The Secretan telescope is in very fine condition. It has completely cleaned, re-lubed and restored.
The views are excellent as you can expect from a Secretan refractor.
