    For a second there I thought you were referring to #astronomy. Can I suggest you start with a decent telescope and point it at the #OrionNebula (below), followed by the tarantula nebula and then Omega Centauri? There's no subscription fee, but you have to get away from #Christchurch's moronic street lighting system in order to marvel at the views. This was taken from my backyard prior to the 5k LED conversion of street lights.

  2. The Neutral Atomic Hydrogen in the solar neighborhood (NeAtHood) project I. Ghost in the shell - neutral atomic hydrogen in the extended Orion nebula: aanda.org/articles/aa/full_htm -> New radio observations reveal hidden structures around the #OrionNebula: univie.ac.at/en/news/press-roo

  3. Had another clear, cool night. I was able to get the Orion Nebula (M-42) and the moon with my #Seestar S30 Pro. The nebula is from a 5 minute/10 second stack of images and the moon is a single shot. The moon was very bright and blotted out all but the brightest stars.

  4. SPHEREx mapping of diffuse PAH and H II emission in the Galactic plane: arxiv.org/abs/2603.23620 -> "Since its launch in early 2025, the #SPHEREx space telescope has been conducting an all-sky near-infrared spectral survey from 0.75 to 5.0 microns. We produce a large-scale map of the 3.3-micron #PAH emission feature, which is bright and detectable throughout the Galactic plane, and find a strong correlation with the thermal dust radiance measured by Planck." (The image shows the #OrionNebula in special false colors explained in the ALT text.)

  5. The Orion Nebula (M42) from last night, in between clouds and a bright Moon washing out everything.

    Haven't done any "prettifying" on this to turn it into art, but as imaging data I kind of like it like this. Science!

  6. Orion Nebula (2022), captured from our terrace in the middle of the city with a Sky‑Watcher Newtonian telescope + Canon EOS 5D Mark III full‑frame cam. Pleased with how much detail came through despite urban light pollution. #orionnebula #graz #astrophotography #skywatcherusa #geoscience

  7. M42, the Orion Nebula. Captured on a SeeStar s50 in Mosaic Mode. LP filter on, 17 minutes, alt/az mode. #SeeStar #SeeStarS50 #M42 #OrionNebula #Astronomy

    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

  9. 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

  10. after a while - i finally came to a bit astronomy. work has filled up my life last months... A glimpse an Messier 42, the Great Orion Nebula. Seeing was cruel and i couldn't do more resolution then 2x2 binning. but i am happy with the result of 30 Minutes photon counting 😉
