The Sternstunden Team


This team takes visitors through our stargazing sessions, guiding them through the night sky. Their passion for astronomy is also their motivation to share it with others. We look forward to our next stargazing sessions with you.




Thomas Grunge

Not only the telescope, but also the mount and tripod are top-of-the-line at Thomas's place. Visitors to the stargazing event notice this immediately when they look through the telescope: the crystal-clear image of the object is perfectly still. It's truly remarkable what such a telescope reveals. No one should miss this sight.


Dr. Gerold Holtkamp

The "big rig" remains permanently mounted at home in his garden. For stargazing sessions, Gerold sets up the portable "small rig." And this one is quite something. As an apochromatic refractor, the telescope delivers razor-sharp images. The moon, Jupiter, and many other celestial objects become an impressive experience. Furthermore, if a computer is connected, the telescope can be automatically slewed to any object in the sky.


Olaf Homeier

Admittedly, his smart telescope doesn't look like a telescope at first glance. But its capabilities quickly become apparent in sufficient darkness. Then Olaf starts up his fully automated device, equipped not only with a telescope but also with a tracking system, a camera, and a computer. This allows him to capture brilliant images of even faint nebulae during stargazing hours, images that remain hidden to the naked eye.


Dr. Achim Tegeler

Achim's large, tracking reflecting telescope is already an impressive sight. But above all, the view through this telescope of celestial objects is something you shouldn't miss. Both its light-gathering power and its resolving ability provide visitors with breathtaking images. Despite its size, the telescope is portable and can therefore be taken along for almost every stargazing session.


Werner Wöhrmann

With this telescope, you're looking through the largest refracting telescope of our Sternstunden. Its sheer size is impressive. But its image quality is equally remarkable. Jupiter's cloud bands or Saturn's rings pose no problem for this instrument. Combined with Werner's expert explanations, observing becomes a truly special experience.
