To test the optical performance of our main instrument, we have now used a large CCD camera in the telescope focus for the first time. This camera is adapted to the telescope focal length, so that the image sampling is...
At the beginning of August, the weather often shows its best side. The nights are already noticeably longer. So it is time again to sacrifice some hours of sleep for the dear hobby and to change it for an experience of...
Trusted journalist Arndt Gaudich caught up on our work progress, reports on the upcoming commissioning of our large telescope, and on our new colleagues.

We have lost a great teacher and friend of the school observatory. Prof. Dr. Wolfhard Schlosser was a founding member and honorary president of our association. He passed away on July 14 after a long illness. Wolfhard...
The telescopes in our School Lab are good for observing the planets. Right now, an opportunity is presenting itself with Jupiter and Saturn. Although Saturn is relatively low above the horizon and the air turbulence is...
The main mirror of our large telescope is relatively thin, but still weighs 80kg. To maintain the nominal mirror shape during telescope movements, it lies on an air bag, whose pressure is adapted to the respective...
In addition to our ‘upper’ auxiliary station at the school lab, we also operate a ‘lower’ auxiliary station. This very first station was already built downhill (i.e. below) our service building...
Next to the school lab we will install our heavy 40cm telescope. For this purpose, we have already poured a separate concrete plate and installed the mounting pier. Astronomy really has a lot to do with concrete. Now...
The phase of the moon at the beginning of May 2022 allowed to test the videography technique to capture high resolution and high contrast lunar photos. Thereby with an astronomical color camera (here: ASI183MCpro) and a...
It is May! The twilight phase is getting longer and longer: currently one waits already more than 2.5 hours after sunset until it is dark and the first photons can be captured. During my journey into the universe...
In order for a telescope to accurately correct for the Earth’s rotation and accurately track objects in the sky, its polar axis must be aligned exactly parallel to the Earth’s axis of rotation. To achieve...
The digital controller, its software and new encoders for our large telescope have now arrived from the USA. We will not only be able to control the telescope but also to completely compensate for structural mechanical...
