This development is now so advanced that it can easily be spotted by astro-amateurs on Earth. Our customer Clyde Foster from South Africa provided us with the following images, taken with Celestron Edge HD 14 and Baader LRGB filters. The red material flows like an arc out of the GRS (which is actually a storm area).
The Great Red Spot is a high pressure area and the largest storm in the solar system that has existed for at least 350 years. Changes to the GRF are nothing new. It has shrunk considerably over the centuries (from three times the size of the earth to earth-size), occasionally it even becomes "pale" orange. However, noone has ever seen such a behaviour before and therefore it can't be predicted what will happen.
Tips for observation and photography
Even with relatively small telescopes (from about 114mm opening, AstroMaster 114EQ Teleskop (#822020, € 229,-) ) and magnifications of around 200x to 250x the GRS and its new "edge", which looks like an eyebrow, should be visually and photographically visible
If you like to observe and take pictures at the same time, our new Baader FlipMirror II (available from July) not only saves you the constant change of eyepiece and camera, but also helps to center the planet exactly on the camera.
About the author
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.View all posts from
