... Construction of the Observatory's principal buildings began in 1789, using plans drawn up by Francis Johnston, one of Ireland's most celebrated architects, a native of Kilmore, County Armagh who in later years became known as `Ireland's Wren'. The main buildings, which are of considerable architectural merit, comprise in their original designation a residence for the Astronomer, a meridian room, a library and several telescope domes. ...

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. ...

The weather is not as bad as one might expect, base on statistics from 1991 through 1993 one can expect about 120 usable nights a year with about thirty of those being totally cloudless. ... This, along with the fact that the telescope drive motor is misgeared, made it difficult for the telescope to collect research data. ... The dome houses a 14" Celestron Schmidt-Cassegrain telescope that was installed in 1981. ...
