About the author

Michael Risch

Michael Risch has been interested in astronomy since he was 6 years old, and in 1981 became a member of the Association of Amateur Astronomers in the Saarland. There he accompanied the construction of the observatory Peterberg as a member of the board. As co-founder and first webmaster of www.astronomie.de, he contributed many ideas to the first German astronomy portal and, as a lifelong academic lecturer, has guided many "Northern lights and stars" tours into the Arctic Circle. Astronomically, he has dealt with planets and comets, sun, deep sky and TWAN-style photography, including many long-distance travels, amongst others to 7 total solar eclipses. Michael has published many of his own photos and articles in journals and authored with his colleague Martin Rietze for "Color Foto" chapters for the books Fotoschule (Photo School) and Extremfotografie (Extreme Photography).

He is part of the observatory project team at Baader-Planetarium and is booked for lectures within the Celestron distribution in Germany and abroad. He is also a consultant for high end mounts, telescopes and much more.


  • Comet Neowise in a different way

    Comet NEOWISE is probably the most beautiful comet since 25 years on the northern hemisphere of the earth. Comets are messengers from the time of origin of the solar system, frozen remnants of the primeval cloud from which the planets were formed. When they come to us from the cold depths of the outer solar system and thaw when they approach the sun, they spread gas and dust and create a unique celestial phenomenon. Most...
  • Mars Opposition 2020 –The Return of the Red Planet

    Do you still remember the lunar eclipse two years ago? At that time the moon was not the only orange-reddish celestial object. Nearby – next to Jupiter – there was Mars in the sky, too. For many people, this was the first time they saw the two planets knowingly "live" – thanks to the attention that the lunar eclipse generated. Unfortunately, the Moon will not give us such a show again this year, but Mars...
  • Comet NEOWISE - now visible!

      Update 09.07.2020: See the new Comet-Gallery with lots of images and videos   UPDATE: The latest images fo comet NEOWISE During the night of 7-8 July, the whole of Central Europe had the special opportunity to see two rare celestial phenomena simultaneously. Around 3 o'clock comet NEOWISE climbed over the horizon. Not much later, the sky behind the dark cloud bank just below the comet suddenly became much brighter. As it turned out, the...
  • The Atmosphere of Venus - Photographed by our Customers

    Venus as a ring – how can that be? During the last days several customers have sent us some very interesting photos of Venus, which we do not want to withhold from you. They show the planet as a very narrow sickle or even as a ring. This effect can only be seen on Venus by observers on Earth, and it is only visible when Venus is in lower conjunction (www.wikipedia.org/Aspects_of_Venus), i.e. when Venus is...
  • UPDATE: Comet ATLAS (C/2019 Y4) is breaking up

    UPDATE 08.04.2020: Comet ATLAS's core is breaking up Unfortunately comet Atlas seems to meet the same fate as many other promising comets did before: The images since April 6th show that the nucleus is breaking up. This can be seen from the fact that the once very concentrated, almost star-shaped inner region has become elongated – in the process it is becoming more and more diffuse and the brightness is decreasing instead of continuing to increase....
  • Modern meets antique: 3.5M AllSky dome in a Greek mountain village

    Our last dome assembly in 2019 took place in the second week of December in Greece. Since this installation had a special flair as well as bad luck and breakdowns, we would like to share with you the following report of the installation. After the dome has been used for some time, we will also ask the customer if he agrees that his dome will appear on our observatory world map. The mountains of the...
  • HALOS – viewed without prejudice

    The moment you insert any type of filter into the optical setup, which consists of your specific camera, the appropriate flattener/reducer or coma corrector and the telescope, the filter becomes part of this unique optical system. And every optical system is different because many products from different manufacturers are involved. All optical surfaces interact with each other in some way. One possibility is that coatings of the camera reflect unwanted light back into the telescope...
