Bamberg refractor

This refractor with 37 cm diameter and a focal length of 7 m is primarily for investigation of apparent magnitude, distance measurement of stars, photometry of stars and to masking the solar observation. It is equipped for this with a photometer.

Cassegrain GOTO

The Cassegrain telescope is a gift from the Japanese government and is equipped with a computer-controlled alignment (GOTO ). The telescope spectrometer can be connected.
