AstroBin's Image of the Day: "The Fading Shockwave of SNR G156.2+5.7" by Stefan Pommerin www.astrobin.com/zajzad/ #astrophotography

It's been cloudy and rainy for what seems like ages now...but this afternoon there was a small patch of clear sky and I was able to shoot the Sun in H-alpha. Our Star is always awesome 🙂. #Astrophotography #Solar

Here’s the last image taken with my ASI2600MM Pro camera right before the power port broke. I just got it back from repair yesterday. The Cone Nebula still looks great considering that I didn’t get more subs due to 📷 failure. #conenebula #christmastreecluster #ngc2264 #astrophotography #nebula

La tempête solaire qui a commencé cette nuit en toujours en cours. Si ça se maintient jusqu'à la nuit, on aura peut-être encore des aurores. Prenez des photos longue pose en direction du Nord !

Le calme après cette tempête géomagnétique. Cassiopée, l'amas de persée et les pléiades surfant sur les dernières luminosités nocturnes de cette session d'aurore boréales.

People in Europe get out and look at the sky 😇

Aurore sous les nuages. Quelle puissance magnétique 🤪

Just finished my final #Pleiades, #M45 image of 2025! Mixed RGB from my Canon R(a) with mono luminance to push detail + color. Winter skies never disappoint. ▼ Baader Apo 95 CaF₂ | SkyEye62AM, Canon EOS R ’25 Full version: astrocamp.eu/en/pleiades-... #astrophotography #astronomy #nature #deepsky

@kat-astro-bot.bsky.social Astrometry Bot update is live. It replies to your astrophoto posts with sky location and object IDs. Call it by: • mentioning it in your post • mentioning it in a comment (bug fix) • mentioning it in a quote • Now supports AstroBin links (beta).

Thanks Kat for your great job about @kat-astro-bot.bsky.social ✌️ For testing new feature, I will share again the teamwork we treated with @clementpiel.bsky.social and @bflachsbart.bsky.social 💫 AstroBot, which target do you see here ? 👉 app.astrobin.com/i/85ijbe

Comet 24P-Schaumasse ☄️ Quickly test.

Comets in process. - 3I/Atlas - 24P/Schaumasse

Review 2025🔭✨ I selected the four best images that I had time to process this year. There are also two other projects in the works that will be released in early 2026. #astronomy #astrophotography

Quelques cibles en cours d'acquisition 💫 ✨Barnard 30 ✨M81 - M82 ✨IC 447 & consorts ✨IC410 Focus sur IC447 et Barnard 30.

This GIF shows the movement of 3I/ATLAS over the course of just under an hour (58 min 30 s). #astrophotography

SH2-216, en SHO, en attendant qu'Orion se lève. L'objectif étant de pouvoir configurer cette cible (fichiers de calibration, cadrage et test rapide d'un rendu). Cible assez technique à première vue mais déjà un peu de signal visible :)

Stacking - All sessions RGB + SHO. I hope to add more sessions in few days. NGC 2245 are starting to be bright 😊

AstroBin's Image of the Day: "LDN 1543" by Joshua Carter www.astrobin.com/stqry8/ #astrophotography

La dernière image de la collaboration FACT, à laquelle j’ai contribué, vient d’être choisie « Amateur astronomy picture of the day » ! 🥳 www.aapod2.com/blog/ngc-702... #astrophotography

Quand ton SSD principal te demande un upgrade depuis 2 ans pour traiter les photons venus du ciel profond... 2To s'ajoutent pour avoir les capacités à pré-traiter de multiples sessions sur la même partition 😀 Les sessions commençaient à dépasser les 256 Go 😅

Sh2-200 The Bearclaw Nebula captured from my patio on six nights last month 😊🔭 This was shot on the EdgeHD 8 for a total integration time of about 55 hours in mono with Ha and OIII narrowband filters and combined with RGB stars. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

👻✨ Started to treat 58 Go of data from the deepsky. Sleeping during astrometry, alignment then seeing this beautify loop (in RGB), around the ghost of casiopea. Stay tuned for seeing the HO-RGB version :)

Conditions inespérées lors de la dernière nouvelle lune. Idéal pour tester l'acquisition de IC447 et le groupement LDN 1608/9/10. En wideband et narrowband.

Premier test rapide sur SH2 263, dans la constellation d'Orion. Capturer les photons quasiment non filtrés, permet encore de voir des choses qu'on ne peut distinguer avec les filtres narrowband. Non filtrés (histogramme) vs SHO (sur caméra couleur).

Un bon début pour Simeis 147 / Sh2-240. Pas facile à faire cette cible mais content d'avoir déjà un bon cadrage pour lancer les acquisitions futures.

🎉 Siril 1.4.0 is out! First Stable version of the 1.4 series 📥 Download: siril.org/download/202.... 🐛 Test it and enjoy! Thanks to our contributors and community! Clear skies! ✨

Somebody are using Tycho tracker here ? Do you need a paid licence for using it ? #astrophotography

La nébuleuse de Pacman, quelque peut décentrée. Quand un loupé reste toujours magnifique à contempler ✨😜

Live Stacking - Part 2 (RGB et un peu de Ha)

Après avoir découvert cette zone, toute proche de la Soul Nebula (avec @bflachsbart.bsky.social), je me permets de vous présenter le live stacking de ce soir :) Avec un léger traitement car elle est difficile à détecter malgré tout. Target : vdb15 / Sh2-202

VdB 14 and VdB 15 captured from my dark site in southern France end of September 🇫🇷 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 5.5 hours using an OSC cam with just the UV/IR-Cut filter. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

Level up 😇 Always with @siril.org for now 😜 Siril / Starnet / GraXpert / Gimp and Siril Scripts. All the processing workflow with OpenSource softwares.

Menkib and the California Nebula. After failing to get the whole nebula into the FOV, I tried something different: focusing on the tension between that beast of a star and the nebula. Gear: 130/910 mm APO, ASI 2600MM Pro & SHORGB filters. Total exposure: ~15 hours over 4 nights. #astrophotography

The Pleiades, M45, a beauty in the dark. Open star cluster only 17.5 LY away in Taurus. Recoginzed since prehistoric times.
