  1. #Orionnebel
    Neubearbeitung der Aufnahmen von 12/2024.

    Mit neu erlernter Software und etwas mehr Wissen ein Versuch einer neuen Ausarbeitung - nicht perfekt, die bogenförmigen Nebel könnten kontrastreicher sein, derzeit mag ich aber nicht noch weiter herumprobieren. 🙄

    Aufnahmebrennweite 750 mm
    Weitere techn. Infos siehe Ausgangströt.

    Ausarbeitung am 10.01.2026 mit PixInsight (+RC-Astro Plugins), RawTherapee, Gimp
    Ursprüngliche Ausarbeitung: Siril, RawTherapee, Gimp

  2. Orion nebula M42 and De Marian's Nebula M43

    Total Integration time: 6 hours, Filter Dual-Narrowband.
    Sub-Frames taken in several nights, starting with 28. dec 2025. Not "the best nights" due to the moon - I know 🙄.

    As my actual focus lies on the horsehead nebula, the orion nebula was done in between (better than nothing). As it is much brighter and at least the important red channel (H-alpha) of the Dual-Narrowband Filter is little affected of the moonlight, I decided to take photos anyway because of the clear sky.

    Also this is my first project done with PixInsight - have still to learn and try a lot.

    Technical Infos:
    Telescope Skywatcher 200mm/1200mm (10" f/6). modified with 3D-printed secondary mirror holder with 3 spider vanes
    Coma corrector: TS-Optics TSGPU
    Filter: Optolong L-extreme, Dual Narrowband (H-Alpha, OIII)
    Camera: ToupTek ATR2600C, cooled color Astrocam, Sensor APS-C (Sony IMX571C)
    Mount: iOptron CEM70
    Guiding: Guidescope TS-Optics 60/248 mm, ZWO ASI 662 MC
    Control via Raspberry Pi (RaspiOS - Debian 13), Indi, KStars, PHD2
    Image processing: PixInsight (+RC-Astro Plugins), RawTherapee, Gimp

  7. Geminiden-Meteor über dem Hohloh im nördlichen Schwarzwald am 14.12.2025. In der Bildmitte leuchtet #Jupiter als hellster Punkt. Rechts davon zeigt sich das Sternbild #Orion mit seinem Gürtel aus drei Sternen, dem nebeligen #Orionnebel und dem rötlichen Riesenstern #Beteigeuze.

  9. Manchmal frägt man sich schon warum man ausgerechnet bei #Astrofotografie gelandet ist.
    Dann arbeitet man das Bild (vorläufig mal) aus, dann weiß man wieder warum. Warum der ganze Aufwand.

  10. Am 30. September 1880, heute vor 143 Jahren, erstellte der amerikanische Astronom Henry Draper die erste Fotografie des Orionnebels.

    Der Emissionsnebel befindet sich im Schwert des Sternbildes Orion und ist ungefähr 1350 Lichtjahre von uns entfernt.
