Silesian Planetarium

The Planetarium's sister astronomical observatory is equipped with a 300-mm diameter refracting telescope (the largest refractor in use in Poland) and a number of smaller instruments.

On cloudless days, visitors can view live images of the Sun and, after dusk, a range of celestial objects at a magnification of up to 750 times.

[1] The Silesian Planetarium, located in Chorzów, Poland, is a renowned educational and scientific facility designed by Kraków architect Zbigniew Solawa.

At its center is a Carl Zeiss projector, capable of displaying over 8,000 stars, making it one of the most advanced of its time.

The astronomical observatory, launched in 1955, houses Poland's largest refractor telescope with a 30 cm diameter.
