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.


  • 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...
  • Don't miss it: Transit of Mercury on November 11th, 2019!

      Transit of Mercury LIVE: NASA is broadcasting the film sequences of the solar satellite SDO for all those who cannot observe the Transit of Mercury on November 11th 2019. The films will be available on https://mercurytransit.gsfc.nasa.gov almost in real time: Starting around 1200 UTC (7:00 am ET) November 11, 2019, we will begin watching Mercury move into view against the corona of the Sun. This is about 45 minutes before it is visible against the...

  • Deep-Sky Astrophotography with the FlipMirror II star diagonal

    Instruction Manual: Baader FlipMirror II Star Diagonal The Baader FlipMirror II (BFM II) in action The Baader FlipMirror II Star Diagonal (#2458055, € 195,-) is not only an accessory for "experts" but also a useful tool that makes the work of every amateur astronomer – especially the astrophotographer – easier.  First and foremost, the BFM II is designed to fully replace your standard star diagonal so that you can continue to observe as normally with...
  • A stroll through Amateur Astronomy - from the Apollo Space Age to modern 10Micron HiTec Mounts

      If you are older than 50 years and were interested in astronomy as a child, you'll surely remember the time when there wasn't such a broad astronomy market as today, with lots of dealers and manufacturers. This was not only because there was no internet – there were also simply no products. Smaller telescopes were rare, as there were only a few manufacturers. It is no coincidence that the first "mass production" in Japan...
  • Observe now: Jupiter is changing

    For several months now, scientists have been observing that the Great Red Spot (GRS) on Jupiter is changing in an unusual way. On the following photo from 22.2.2019 – taken by the US space probe JUNO which is currently orbiting Jupiter –  you can see that the GRF had already started to change in February and is literally "flowing out". This development is now so advanced that it can easily be spotted by astro-amateurs on Earth....
  • Hurry up to observe Comet C/2018 Y1 Iwamoto!

    One more fine comet for binoculars As soon as comet Wirtanen has gone on distance to Earth, C/2018 Y1 Iwamoto enters the stage. It passes through the constellations of Leo, Cancer and Gemini and is currently visible all night long. The comet Iwamoto is just below the limit of perceptibility with the naked eye, and a small pair of binoculars will easily show it. It is an ideal target for astrophotographers. Unfortunately, the waxing moon...
  • First images of comet 46P/Wirtanen with RASA 8

    The Comet 46P/Wirtanen approaches the earth and becomes brighter and brighter. Latest estimates (December 3rd) are about 5m, so theoretically it should be visible with the naked eye. However, its brightness is distributed over a full moon size in the sky, thus the surface brightness is low. To see such a special comet you need a very dark sky. And to be able to photograph it, suitable optics with high light intensity and short focal...
  • Impressionen der Mondfinsternis 2018

    Mondfinsternis-Viewing mit Baader Planetarium Erstmalig in unserer Firmengeschichte haben wir eine kleine "Star Party" für ein astronomisches Event veranstaltet. Am Haldenberg, in der Nähe unseres Firmensitzes Mammendorf, haben wir einige Teleskope aufgebaut und dies vorab in den Lokalzeitungen verkündet. Da wir nur eine begrenzte Anzahl an Mitarbeitern für dieses Event zur Verfügung stellen konnten, haben wir die Veranstaltung bewusst nicht im Vorfeld online beworben, um nicht "überrannt" zu werden. Doch auch so hat sich die...
