  1. Size does matter! On the left is the old ball head, which always made me wonder why the camera was shaking and I couldn't focus on a subject. On the right is the new one, and now I understand why. Now I managed to capture Orion in the frame – my first ever image of the #orionnebula

    - 29 minutes of exposure
    - My wife's Pentax K30 (€0)
    - 70-210mm f/3.5 lens (€20 from eBay)
    - #barndoortracker (approx. €100)

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

    Total Integration time: 10 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
