Teachers from the Marienheide and Betzdorf comprehensive schools want to use the observatory with their pupils in the near future. To this end, they discussed with us the astronomical possibilities on site, a possible...
After the steel frame of the upper auxiliary station has been completed a few days ago the walls have now been put in place and the shelter building completed accordingly. The station is ready for instrumentation, for...
Students of various technical-scientific disciplines and accordingly scholarship holders of the Hans Hermann Voss Foundation, visited our observatory. Intention was the insight into our work, our goals and our observing...
