About the author

Martin Rietze

Martin Rietze has been an enthusiastic amateur astronomer for over 30 years. He has photographed 9 total solar eclipses and many other celestial objects, including many comets. From his countless trips abroad he brings back photos of the nightsky with fantastic scenery. His main passion, however, is volcano photography, for which he mainly travels around the world. His absolutely inspiring pictures can be found on his private website www.mrietze.com, one of his volcano pictures even made it to NASA APOD. Together with his colleague Michael Risch he has written chapters for "Color Foto" for the books Fotoschule (Photo School) and Extremfotografie (Extreme Photography).

As a trained electronic engineer, he is responsible at Baader Planetarium for the dome electronics and computer installation in observatories and research stations worldwide and has planned and built domes in the North Polar Circle and Antarctica. He is also very familiar with the CCD technology of DSLR cameras and all kinds of optics.


  • Solar Eclipse 2019 in Chile

    For years our colleagues Martin Rietze and Michael Risch have been hunting for the next solar eclipse in the most remote places in the world. See e.g. our previous blog posts, some on AstroSolar.com: 2015: Solar Eclipse Adventure in Svalbard 2016: Solar Eclipse on the Molucca Islands 2017: "Great American Eclipse" in USA 2019: Sonne2019: Solar Eclipse in South America As already in 2017 Martin Rietze travelled alone to the Eclipse in Chile. Below you can see a short time-lapse video of the solar eclipse, in which you can see very impressively the shadow of the moon travelling over the earth. Here you can download the video of the Solar eclipse 2019 in FullHD.

  • Comet Filters

    The two tails of the comets   The most impressive tail of a comet is caused by sunlight which is reflected and scattered by the dust trail of the comet - also called dust trail. In addition, there is often a gas tail, depending on the amount of gas emitted by the comet. This gas is ionized (excited to glow) by the energy of the solar wind. This ion tail shines preferably with the emission lines of OIII (501nm) and Cyan (511 and 514nm). If you want a better contrast for the comet in the sky, you must consider the following with the choice of suitable filters: There is no way to show only only the dominant light fractions of the dust tail (as with...
  • Team Baader at the "Great American Eclipse" 2017

    For years our colleagues Martin Rietze and Michael Risch have been hunting for the next solar eclipse in the most remote places in the world. See e.g. our previous blog posts on AstroSolar.com: 2015: Solar Eclipse Adventure in Svalbard Martin Rietze and Michael Risch from Baader Planetarium – both solar eclipse chasers – have again traveled to the event and brought us impressive images and videos. Svalbard is one of the few islands where the path of totality on March 20th, 2015 crossed land. Its 1300km from North Pole Our chances for good weather were somewhere around 50% so it was more or less gambling flying there to see the Total Solar Eclipse... 2016: Solar Eclipse on the Molucca Islands After last year´s amazing eclipse...
