Historische Newton telescoop

Soms moet je het niet zo ver zoeken.

In een buurgemeente stond de telescoop van de vader van een vriend werkloos in een garage.  Een prachtig historisch instrument.

De hoofdspiegel heeft een diameter van 25cm met een brandpuntsverhouding van 5.5 en werd gemaakt door Zeiss, Jena.  De telescoop en montering werden gemaakt uit onderdelen van Manents refractoren.  De originel
