The planetarium has been operating since 1971 and is in the fabulous city of České Budějovice, in the Southern Bohemian region of the Czech Republic, in a busy waterfront setting popular with space fans.

In 2019 as part of a renovation, a new dome screen was supplied in partnership with Sky-Skan Europe of Munich, Germany. The project led by Sky-Skan involved the refurbishment of the original Zeiss ZKP-1 star projector and the light source was also upgraded to LED and mounted on a lift. A new Sky-Skan Definiti 4K Compact projection system was installed providing over 4K pixels of screen resolution (10+ megapixels in total).

The 8.3M diameter dome provides a 180-degree field of view and was supplied and installed by Endurescreens.

As the Pro+ seamless dome screen had to be installed on a ledge within the circular part of the building, and with the tight constraints put in place by the size of the existing building, our design team had a challenge on their hands. They had to customise many features of the structure for it to fit, but in the end this uniqueness was all worth it as the finished result was perfect.
