OBSERVATORY AND PLANETARIUM
The observatory and planetarium are located on the southern outskirts of Hradec Králové. The basic construction took place between 1947 and 1961. The site for the observatory was chosen on the ridge between Zámeček and Nový Hradec Králové. The position of the main dome is 15° 50′ 21″ east longitude, 50° 10′ 38″ north latitude, 287 m above sea level. The observatory has a large number of instruments, for example the historic planetarium ZKP-1 has been used at the Hradec Králové observatory since 1957. At the beginning of 2015, a new digital planetarium was opened with five Velvet projectors that produce images on a 12-metre diameter hemispherical projection screen. The building also houses a branch of the Czech Hydrometeorological Institute – Solar and Ozone Observatory.
