This was mine this morning 😊

For the folks that are still struggling with this. Here is a Venn Diagram. #3I/Atlas #3I 🔭

The Horsehead and Flame Nebulas 🔥 I tracked this dramatic area in 'Orion's Belt' for nearly 8 hours to capture the light for this photo. For a deep-dive on the telescopes I use for photos like this (including this one), check out my updated guide: astrobackyard.com/best-astroph...

The Star we know best, the closest one to us, the #Sun, shot around mid day in H-alpha with my little Lunt Solar scope. #solar #astrophotography

Science is losing.

Et soudain, après une averse, un ciel magnifiquement clair ! Ni une ni deux, je sors le petit scope 🔭 connecté, direction, la nébuleuse de la tête de cheval 🐴 et la nébuleuse d'Orion... #Seestar le chasseur de troué de beau temps ! ☺️J'ai les sub's de cette captation, traitement Pixinsight à venir...

What's cool about #astrophotography 🔭📷 is that you can stack frames to create nice images, and also use those frames to do some aperture photometry (here with AIJ on the eclipsing binary V1337 CAS near IC1805 Heart Nebula AIJ). Ain't that cool people 🤓? What do you see @kat-astro-bot.bsky.social ?

Et voici la réponse ce regard appartient a une belle force tranquille, une peau rugueuse mais un caractère doux et paisible! Le requin nourrice ou dormeur au choix !!

On teste, encore et encore, même à travers les nuages 😶‍🌫️😜 J'ai même un morceau du cluster M12 avec la comète C/2025 A6 Lemmon 💫☄️ C'est complexe, notamment au crépuscule, les nuages sont toujours présents.

Open Sesame! The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed. The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert. https://www.eso.org/public/videos/potw2544a/ 🔭 🧪 📹 ESO/ACe

Solar #astrophotography 🔭📷 does have its perks...like getting your images taken in 10 minutes between two rainy episodes. This is the Sun as it was late this afternoon in France, shot with my Lunt 60 and my ASI1600GT mono camera and dodging quite a few clouds and rainy spells.

Hello les amis ! Enfin de retour chez moi, j'ai pu traiter la nébuleuse de la tarentule, prise avec le RASA 14 au Chili de l'OBP. SO MANY STAAAARS ! Un sacré bonheur d'avoir accès à ce genre d'image ! #astrophotography 🔭

Et voici C/2025 R2 (SWAN) prise en 18minutes avec le RASA 14" de l'OBP au Chili sur les filtres RVB. Un traitement de comète en mono... il faut vraiment pas être bien dans sa tête 😂😂 (coucou @pahcas.bsky.social ! Je pourrais jouer encore avec votre jouet à l'occasion ? 😇) #astrophotography 🔭

LDN 1165 captured on two nights a couple of weeks ago 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of 7 hours in OSC and Mono. I used the mono Ha data to enhance the red and the luminance details. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

#inside the stillness of dawn. #blueskyartshow

Longing for a gentler timeline that is less fascist and less full of ignorant people For example Biff's 1985

On this day in 2021 I was capturing the Waning Gibbous Moon. 🔭 🧪 🎨 #astrophotography #SciArt #photography #StormHour #ThePhotoHour

uv makes installing and using Python *so* easy! It works on pretty much any computer and it's lightning fast. 🔭☄️ #astrocode If you're still using conda, pyenv, or... basically any other tool, then I can *highly* recommend switching:

Dark dust clouds in Perseus with the #Embryo nebula NGC1333 in the bottom left corner. Shot this 7 days ago from my backyard. #astrophotgraphy 🔭📷 reveals what our eyes won't always see....but it's not because we don't see it that it's not there. Where do you put this @kat-astro-bot.bsky.social?

But I am proud to provide free photos day in, day out, as far as I possibly can. I Thank you, and clear skies to all you amateur stargazers and night sky lovers! Below: "E" = Enjoy

Ngc7331 et le quintet de Stephan, la semaine dernière, depuis chez moi sur 6h, au c9.25.

La cometa C/2025 A6 Lemmon ripresa dal colle del Gran San Bernardo, in Valle d'Aosta, da Alessandro Cipolat Bares. Domani il massimo avvicinamento alla Terra. È di poco oltre il limite della visibilità a occhio nudo. Guardate verso ovest da luoghi bui, possibilmente con un binocolo

✨ M36, M37 and M38 are open clusters in the constellation Auriga. M36, 4,100 light-years away, is relatively young and contains at least 60 #stars. M37, the richest of the trio, is 4,500 light-years away and contains over 500 stars, while M38, 4,200 light-years away, appears larger in apparent size.

The area around LDN 879 in the Cygnus constellation, close to the bright star Sadr, about 5,000 light years away from earth. Not the most popular target in Cygnus, but there’s a lot going on here. A complete rework of my narrowband data captured with an 8" Newton & ASI1600mm. #astrophotography

Flow! @bsky.app #landscape#art#photography

I tried my best to capture an L-RGB image of comet C/2025 A6 Lemmon using a monochrome cam. It's feasable, but it's not as nice and starightforward as with a color cam because Comets move fast!!!!! #astrophotography. Where's this @kat-astro-bot.bsky.social ?

Thanks 🙏. The setup used and details are on my Astrobin www.astrobin.com/lfv1ja/

Hi all #astronomy fans out there ✨! I managed to shoot the Cocoon Nebula (IC5146) and its trailing dust train over the past two nights, using my backyard #astrophotography setup. The weather Gods blessed me I guess 😇. Lots of Hydrogen in the background. What's out there @kat-astro-bot.bsky.social ?

Again nice prominences today on the Sun! Captured with an SHG 700 and processed/stacked using JSol'Ex! #solar #astrophotography

Lemmon juice being squeezed out of the comet C/2025 A6 #astrophotography. Shot this evening but it's really low so it is tough to even think about getting this one done in RGB. Can you try and solve this one @kat-astro-bot.bsky.social ?

The North America, Pelican and gulf of Mexico (yep, not the "gulf of America" 😇) nebulae to which I added SII subs last night from my backyard. SHO is an unusual #Astrophotography 🔭📷 palette but I do like it. I'm pretty sure @kat-astro-bot.bsky.social will solve this one in a breeze.

J'en ai profité pour en faire également une version en HOO ✨

From my backyard : Summer is going away gracefully, and with it the North America Nebula NGC7000 in the Milky Way plane. I count around 69 000 stars in this #Astrophotography 🔭📷picture! Can you guess where this is @kat-astro-bot.bsky.social ?

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.

LBN 437 The Gecko Nebula captured from my dark site in southern France last month 🇫🇷 😊🔭 It was shot on the EdgeHD 8 with Hyperstar for a total integration time of 8 hours in OSC and Mono. The red nebulosity was enhanced with Ha data. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

On October 14, 2025, an exceptional event will be observable by astronomers in Western Europe: #Ganymede, Jupiter's third moon, will #occult a magnitude 7.5 star (HIP 37442), causing a slight decrease in brightness of 0.1 magnitude for 17 minutes. #astronomy #proam gemini.obspm.fr/20250609-occ...

The Tadpoles in Auriga shot in narrow band SHO (Sulfur, Hydrogen, Oxygen) from my backyard during last night's #Astrophotography 🔭📷 session. Slightly psychedelic colors but I like those 🫠. The stars are RGB though. Am I spot on @kat-astro-bot.bsky.social ?

Frozen art from nature in Greenland…

The bane of all #astrophotography 🔭 📷 amateurs is stars throwing a tantrum right next to tiny, delicate, nebulae...Navi is such a star, glowing from just beyond the top left corner of this image of the Ghost of Cassiopeia #IC63 I shot from my backyard 🙂. What do you see @kat-astro-bot.bsky.social

The Sadr Region, glowing in the heart of Cygnus. Captured last night with 2 hours on each SHO filter. Just a small attempt to show the beauty that’s already there. #Astrophotography #Nebula #SadrRegion #Cygnus #NightSky

J'ai le grand plaisir de vous annoncer la sortie du film de planétarium "H2O, les états cosmiques de l'eau" sur lequel j'ai travaillé en tant que conseil scientifique. Ce film (dispo en FR et EN) est destiné à être projeté sur tous les dômes des planétariums qui le désirent.🧪 Ce film raconte (...)

LDN 1251 The Rotten Fish Nebula captured from my dark site in southern France this month 🇫🇷 😊🔭 This was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 4 hours using an OSC cam with just the UV/IR-Cut filter. #Astrophotography @kat-astro-bot.bsky.social‬ what do you see?

SH2-114 The Flying Dragon Nebula captured from my dark site in southern France this month 🇫🇷 😊🔭 It was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 11 hours in mono using Ha and SII filters and combined with OSC stars. #Astrophotography @kat-astro-bot.bsky.social‬

Bon, hum, les LLM ont encore quelques progrès à faire 😅
