"The main telescope of NAO - Rozhen is a 2 meter reflector, optical system Ritchey-Chretien-Coude, made by Carl Zeiss, Jena. This is still the biggest telescope in South-East Europe. To the telescope equipment belong: a dual channel focal reducer (F/2.8), CCD Photometrics (1024x1024, px = 24µm) and CCD VersArray 1330B (1340x1300, px =24 µm). Both CCD cameras are nitrogen cooled. The second CCD camera has been sponsored to NAO- Rozhen by UNESCO-ROSTE. In the Ritchey - focus (F/8) direct frames could be obtained with limiting stellar magnitude 22m. In the Coude - focus (F/36) spectra could be obtained with 3 different cameras: 18A/mm, 9A/mm and 4A/mm. The spectral resolution is ~ 30000. The second telescope of NAO-Rozhen is a dedicated photometric telescope, 60 cm Cassagrain. It is equipped with an USB, photon-counting, single-channel, computer-controlled photometer. The third telescope of NAO-Rozhen is 50/70 cm Schmidt telescope for wide-field observations This telescope is equipped with an SBIG ST8 CCD camera."

Üdvözlettel, Géza
