The telescope is equipped with single order and echelle spectrographs, and a CCD photometric camera.<\/p>\n\n\n\n<p>The telescope has been in operation since 1967, when it was commissioned on the occasion of the XIII General Assembly of the International Astronomical Union (IAU). <\/p>\n\n\n\n<p>The most significant and fundamental upgrade of the telescope was performed in 2019. The optical configuration was completely changed, the smaller mirrors in original optical system were removed and the optical fibers from the primary focus of the main mirror to the coud\u00e9 rooms with spectrographs were installed.  With this upgrade, a higher efficiency and extension of the observational limits were achieved. The possibility of observing fainter objects broaden the number of observing programs which can be performed with the Perek 2\u2011m telescope. <\/p>\n\n\n\n<p><strong>This modernization opens new horizons and offers Czech astronomers a device that will stand up on an international scale.<\/strong><\/p>\n\n\n\n<p>The last reconstruction of the Perek telescope is described by Miroslav \u0160lechta in the article <a href=\"http:\/\/stel.asu.cas.cz\/cs\/wp-content\/uploads\/2022\/02\/slechta_Perek2mTel_astropis2020.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Modernization of the 2m Perk telescope in Ond\u0159ejov<\/a> (in Czech), which was published in the <a href=\"https:\/\/www.astropis.cz\/archive\/126.listing\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Astropis<\/strong><\/a> magazine (volume: 2020, issue: 3, pp.: 12\u201315).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"usage-of-the-telescope\"><strong>Usage of the telescope<\/strong><\/h4>\n\n\n\n<p>The telescope is regularly used for scientific observations.
