Comet Nishimura C/2023 P1

M101 with Supernova SN2023ixf

The image above shows the type II supernova SN2023ixf in the galaxy M101, 21 million light-years away, discovered by the Japanese amateur astronomer Koichi Itagaki on May 19, 2023 at 19:45 UT.

Unfortunately, the conditions were not optimal, the moon and stray light interfered. The image was taken on the night of May 31, 2023 and was exposed with 15x60s on a Takahashi refractor TSA-120, 900mm focal length, with an EOS250D at 1600 ISO. (Detail of the original image)

Jupiter and Venus - astrophotography with the simplest means

The image above was taken on 01.03.2023 at around 18:50 in front of our observatory. It shows Jupiter and Venus (from left to right) at a distance of approx. 40.5 arcminutes, as well as the dome. The closest approach of the two planets took place on 02.03.2023 at around 12:00 noon with a distance of approx. 32.5 arc minutes, i.e. approximately the diameter of the full moon.

I used an EOS250D with an EFS 18-55 lens plus remote shutter release on a conventional photo tripod. 1600 ISO, exposure time 1/8s, aperture 5.0, with 31mm and manual focus.

Video of a meteor recorded by an AllSky7 camera at Zweibrücken Observatory on the night of December 14/15, 2022 shortly after midnight. The meteor belongs to the Geminids, a meteor shower that appears to come from the constellation of Gemini. However, the cause of the meteor shower is interplanetary dust clouds originating from the asteroid Phaethon. The Earth passes through these dust clouds every year in the days around 14.12. The dust particles burn up as they enter the atmosphere, causing trails of light. The camera is maintained by our member Rouven Ipser.

Video of a meteor recorded by an AllSky7 camera of the observatory in the night of 14th/15th December 2022 shortly after midnight. The meteor belongs to the Gemini shower which apparently originates from the constellation Gemini ("The Twins"). In reality, the Earth crosses the dust clouds which emanated from an asteroid named Phaethon. The dust particles evaporate when entering the atmosphere causing a light trace. The camera is operated by our member Rouven Ipser.

Sun photographed with solar telescope

The photo of the sun was taken with our solar telescope through a Fabry-Perot filter, which serves as a bandpass for the H-alpha line. This allows the prominences at the edge of the sun to be made visible. These can reach up to several 100,000 km into space. For comparison: the diameter of the sun is approx. 1.4 million km. The black dots and thread-like formations are sunspots. Here the temperature of the sun's surface is lower than in the other areas. Image taken on 27.06.2022.

This image was taken with our Sun telescope through a Fabry-Perot filter which acts as a bandpass at the H-alpha line and renders the prominences at the rim at the Sun visible. These may extend up to some 100 000 km into space. The diameter of the Sun is approximately 1.4 Mill. km. The spots and filaments represent cooler areas of the Sun's surface.

Comet/Comet Neowise

Comet Neowise on 12.07.2020 photographed with our C14 reflector telescope. In July 2020, its distance to Earth was approximately 120 million km. Together with the parameters of our telescope, the apparent diameter of the coma can be calculated as 50,000 km. The coma is gaseous. However, the comet's solid nucleus is much smaller and its diameter has been estimated by professional astronomers to be about 5 km. The image also shows how the tail develops from the coma. 

Photo of Comet Neowise taken on 07/12/2020 through our mirror telescope C14. In July 2020 its distance to Earth was about 120 Mill. km. The photo shows the so-called coma which is a gaseous structure. It can grow to a size of 2-3 Mill. km. Using the parameters of our telescope, we estimate the apparent size to be about 50 000 km. The nucleus of the comet, i.e. its solid core, is much smaller. It was estimated by professional astronomers to be 5 km in diameter. One can also see how the tail emanates from the comet's coma.
