History

The Perek’s 2-metre telescope in Ondřejov has been in operation since 1967, when it was commissioned on the occasion of the XIII General Assembly of the International Astronomical Union (IAU). The construction of the dome began in April 1963.

The construction of the Perek’s 2m telescope started in January 1966 by Zeiss in Jena, and in October 1966, the telescope was transferred to the Astronomical Institute and consequently disassembled and moved in parts to Ondrejov where it was again reassembled. This final assembly was completed in February 1967 and first light through a eyepiece occurred on 8th March 1967. The telescope was officially inaugurated on 23rd August 1967 during the XIII. International Astronomical Union General Assembly. The first spectrum was acquired on 13th October 1967.

From the beginning, the telescope was primarily used for spectroscopy. Initially the spectra were first exposed on photographic plates and from 1992 electronic detectors were used. From 1992 to 2000 a Reticon detector was used and since 2000 CCD chips.
