In the 5 meter dome is a Ritchey-Chrétien-Cassegrain telescope with a diameter of 637 millimeters from the Italian company Marcon.
Planet path
Right next to the observatory, the almost 6 kilometer long planet path begins with the first fixed point, the sun. The path leads via Cheerwald to Heiligenschwendi or back to Schwanden.
history
In 1994 Theo Gyger presented the idea of building an observatory with a planetarium. Gyger was the president of the Schwanden-Tschingel-Ringoldswil (STR) Tourism Association. The project was supported by the Bern professor emeritus Paul Wild, director of the Bern Astronomical Institute. On November 24, 1995, the Astronomical Association of the Bernese Oberland (AVBeO) was founded on Meielisalp above Leissigen . She took over the project from STR Tourism and pursued it further. On October 1, 1999, the permits and the financing for the new facility were in place. The facility was opened on Saturday, October 14, 2000. The astronaut Claude Nicollier was among those present . The facility is wheelchair accessible. The SIRIUS Planetarium Observatory Foundation was established on November 28, 2006, and AVBeO, as the founder, brought in the facility as foundation capital and is now the foundation's patrons' association.
