    The northern light dances in the Arctic Circle

    The report describes what has to be taken into account for successful sightings of the northern lights. In addition, factors that cannot be influenced, such as the weather and the space weather, are also mentioned. Recordings and videos of the northern lights are shown. In addition, numerous sources are listed for more detailed information.

  • Transitlichtkurve des Exoplaneten TOI-1259 A b am 25./26.9.2023

    Transit light curve of the exoplanet TOI-1259 A b on September 25th/26th, 2023

    Der Vorbeizug (Transit) des Exoplaneten TOI-1259 A b vor seinem Mutterstern, der eine Komponente eines Doppelsternsystems ist, wird gezeigt. Die aufgenommene Lichtkurve stimmt gut mit den Messungen anderer Autoren überein. Eine genaue Fehlerbetrachtung gibt Hinweise zur weiteren Verbesserung dieser sensiblem Messmethode.

  • Bau einer Taukappe

    Construction of a dew cap

    The construction of a dew cap for a Newton telescope with a 250 mm aperture is described. Simple and therefore inexpensive means are used, essentially an insulating mat and a Velcro strip. The work process is described step by step.

  • WHAT – Westhavelländer Astro Treffen 2023

  • Messung der Transitkurve des Exoplaneten TrES-3 b am 27.5.2023

    Measurement of the Transit Lightcurve of Exoplanet TrES-3 b

    The transit light curve of the exoplanet TrES-3 b was recorded and measured on May 27th and 28th 2023. The method used and the specific observation conditions are explained. The results are presented and discussed based on an evaluation in the international Exoplanet Transit Database (ETD). The own result is a contribution in the context of so-called citizen science for further exploration of exoplanets.

  • Innerhalb und außerhalb unserer Milchstraße

    Inside and outside our Milky Way

    Color images with the mono camera QHY268M are shown. For this purpose, Fab filters are also used. The particular challenge was that one object stood above the bright city center of Osnabrück and the other object was very disturbed by the moon with 70% illuminated area.

  • Komet C/2022 E3 (ZTF)

    Komet C/2022 E3 (ZTF)

    A comet is a fleeting visitor. This also applies to comet C/2022 E3 (ZTF). On December 31, 2023 it was in the northern sky over Osnabrück and on February 13, 2023 it was already in the south. The following photos were taken from a garden in Osnabrück.

  • „Soeben“ entdeckt – Exoplanet TOI-1259 A b

    "Just" discovered - Exoplanet TOI-1259 A b

    The transit light curve of the exoplanet TOI-1259 A b, discovered just two years ago, was measured. The data determined agree well with literature values. It is a double star system, which is additionally interesting. The close position at the north celestial pole allows interesting further observations.
