Vilém Gajdušek (1895–1977) was Czech optician and prominent telescope designer. Asteroid 3603 Gajdušek is named for him.
Asteroid 8229 is named in honor of František Kozelský (1913–2003 ), a Czech telescope maker well-known for his work in collaboration with V. Gajdušek. Kozelský. Kozelský made several 60cm Cassegrains and a series of 20cm refractors for observatories in Czech Republic, Slovakia and the rest of former Eastern Europe.
Hvězdárna Ždánice (1963) was the first big project by Gajdušek and Kozelský. The Public Observatory had two domes with a 20cm and 16cm equatorial mounted refractors, two 25 cm Classical Cassegrain and a set of smaller optical instruments. With it annual 15 000 visitors it was one of the most succesfull observatories of Eastern Europe in the 1960’s and 1970’s.
Now the observatory is closed.
