He has been practicing planetary, comets, solar, deep sky as well as TWAN style photography, and has been on many long distance trips, among others to 7 total solar eclipses. As co-founder and first webmaster of he contributed numerous ideas and reports on astronomical and spaceflight topics to the first German astronomy portal. In 1981, he became a member of the Association of Amateur Astronomers in the Saarland and, as a member of the board, accompanied the establishment of the Peterberg Observatory. Michael Risch has been interested in astronomy and spaceflight, since he saw the last moon landing as a child. We are happy about any report on this, which we will gladly publish in our blog. Surely many more amateur astronomers will try out more new ideas with our filters in the coming years.

Using these filters on planets and thus contributing to research is again proof of how creative amateur experiments with new technology can complement professional research. for determining the physical properties of stars in particular.

This pdf explains the observation techniques.Īctually, the SLOAN filters are designed for photometric measurements, i.e. Amateur astronomers are encouraged to help investigate the phenomenon. This structure has been the subject of research since its discovery by the Japanese Venus probe Akatsuki, and it is thought that by observing it, we can gain insights into the extremely fast rotation of Venus' atmosphere. Equipped only with a Celestron C14 telescope and using a Baader SLOAN z` near-IR filter, it was possible to visualise a wall of cloud thousands of kilometres long which circles Venus at high speed. Find the original article on Īs the well-known website reported on, a strange effect was rediscovered in the course of amateur monitoring of the Venus atmosphere: the so-called " Venus cloud discontinuity". Venus Cloud Discontinuity, captured by Luigi Morrone on 4th of June 2022 with Baader SLOAN-Filter. It is still a subject of discussion why the photos show the surface Amateur astronomers do science This is thermal radiation directly from the surface of the rock. To the amazement of the scientists, photos of the night side of Venus very clearly showed the surface structures known from the radar scans of the Magellan probe - in the infrared part of the spectrum. On its way to the Sun, this probe passed Venus several times and delivered images with instruments that were actually intended for observing the solar corona.
In 2021, images of the Parker Solar Probe gave an idea of how far we still are from a complete understanding of Venus' atmosphere. Its infrared photos show not only a completely overexposed day side of the planet, but also the almost ghostly infrared glow from the depths of the planet on the night side - and above it the sulphur dioxide clouds as dark shadows The best results so far have been achieved by the Venus probe Akatsuki. The question of whether the very bottom of the surface can really only be explored with radar, or whether the infrared radiation of the hot rock can be recorded directly with appropriate technology, could only be answered decades after the Magellan mission. The US space probe Mariner 10 delivered the first images during a flyby in 1974. It has been known for some time that various structures in the clouds are visible in ultraviolet light. There are only a few narrowly limited wavelengths in which a space probe camera or even a terrestrial telescope can hint at what lies beneath the cloud cover, which for the visual observer is simply brilliant white and contourless. This atmosphere consists of 90% carbon dioxide, a dense layer of sulphur dioxide clouds makes it opaque to us. The reason for this is an enormously dense atmosphere, which generates a pressure that only exists at an ocean depth of 900m on Earth. Venus is a hellish world with temperatures of up to 450 degrees at the surface. It is as big as the Earth, but extremely different from it. For example, our new photometric filters now open another window into the depths of the atmosphere of the planet Venus.
