Description and Technical Details . In 1980s two medium-size horizontal solar telescopes 50/35000 cm with large spectrographs Czerny-Turner made by Carl Zeiss Jena were installed in the Ondњejov observatory. The Czerny-Turner-spectrographs in the Ondњejov observatory called HSFA1 and HSFA2 according to the German name Horizontal-Sonnen-Forschungs-Anlage ("horizontal device for solar research") have been explored for more than two decades. ...

About us . ... Telescopes . ... Apart from the 6-meter telescope BTA two small telescopes are operative at SAO: the 1-m and 0.6-m telescopes, both manufactured by Carl Zeiss, Jena, are located near the BTA. ... These telescopes are used for adjusting the equipment and techniques of observations used at the BTA. ... The observational time allocation and also a brief description of the equipment of the 1-m telescope, which is used either permanently or mainly on this telescope, are presented below. ...
