Stockholm Centimetre Radio Telescopes

The Stockholm Centimetre Radio Telescope (SCRT) consists of two 2.3 metre dishes equipped with 1420 MHz detectors sensitive to the hydrogen 21 cm spectral line. The telescopes are located on the roof of the main building of Albanova University Centre at Roslagstull in Stockholm.

The telescopes are only used for educational purposes where the students, typically undergraduate university students or advanced high school students, systematically can build a map of the Milky Way and its spiral arms.

It is possible to control the telescopes and do all observations remotely over the internet. If you are interested to run the telescopes, please feel free to contact us.

The SCRT has been set up and is operated through the combined efforts of the Astronomy Department and the Physics Department of Stockholm University.
