These are all bad images. Anyway, here’s mine.

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?

Hey all you #astrophotography fans out there, this a ridiculously (in a positive way) astounding image of the Iris Nebula and surroundings : www.astrobin.com/9mj93n/ I'm dumbfounded!

Another version with a brighter and more natural sky background... 🔭📷 #Seestar S50 Ping @ltno2.bsky.social; @vbioret.bsky.social ; @martialrelier.bsky.social; @alrouen.bsky.social ... 😉

✨The Horsehead and Flame nebulae. The difficulty of this capture was keeping Alnitak, one of the brightest stars in Orion’s belt, under control. 📷Setup : Sony A7S, Newton 130/900. @kat-astro-bot.bsky.social what do you see ? #blueskyartshow #sky

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?

Little TV screens at the gas station pump blaring ads directly in your face as you spend $70 on a tank of gas is enough to radicalize a person

Et voilà ! Merci à vous, vous êtes 1000 ! Et pour fêter ça, voici une nouvelle photo des Pléiades ! Et je pense que c'est ma meilleure photo, toute cible confondue... Et chose amusante, pour obtenir ce résultat, j'ai tenté : je n'ai mis aucun filtre ! 😁 Vous en pensez quoi ? 😇 #astrophotography 🔭

Très fier d’avoir reçu le Grand Prix de l’innovation SAF ! 🏆 Nous avons été récompensés par la Société astronomique de France et son président, Roland Lehoucq pour le projet #SUNSCAN by #STAROS. Une réussite collective avec V. Desnoux, C. Buil, O. Garde et Matthieu Le Lain (@matlastro.bsky.social)

The #Sun this morning was very cooperative, shot with my Lunt 60 H-alpha scope. The rendering is in false colors (H-alpha is a deep deep red). #Solar #astrophotography

Looks like there's no @springernature.com breakthrough in medical frymblal after all! Would still be interesting to learn why slop like that was published in the first place.

Ce sont bien des feuilles de ginkgo, oui. Mon arbre préféré 💙 Ben crée des choses magnifiques en origami, allez faire un tour sur son site ✨️

Hello ! Vous vous souvenez ? bsky.app/profile/mart... Bah finalement, grâce à une astuce géniale donnée par @ltno2.bsky.social, j'ai pu sortir cette courbe ! Et on j'ai clairement détecté une exo planète 😁😁 Bon... j'ai pas d'assez bonne données pour que ce soit utilisable... mais JE L'AI EUE ! 🔭 🤯

Une autre Jupiter du 21 mais la nuit d'avant. Conditions rock'n roll. Appréciez la pénombre autour de l'ombre de Ganymède.

Bon... on atteindrait pas les 1000 bientôt ? Je sais ce qu'en dirait @astropierre.com, que ce nombre n'a pas d'intérêt en dehors de la base 10... Mais tout de même ! à 1000 je vous publie ma plus belle photo, faite cette semaine, et je vous révèle ma complice du dernier post 😁😁

A bit of #astrophotography drizzling, cropping, and sizzling on #M82 to show just how gorgeous those H-alpha jets are 😍. Can you please plate-solve this @kat-astro-bot.bsky.social ?

Marrying H-alpha and LRGB data while doing #astrophotography can reveal cool things in space like those reddish jets of matter coming out of the nucleus of M82 (a buddy of M81, one of our neighbor galaxies). Where do you put this @kat-astro-bot.bsky.social ?

The California Nebula (NGC 1499) is an emission #nebulae in Perseus, glowing about 1,000 light-years from Earth and stretching nearly 100 light-years across. Its deep red light comes from ionized hydrogen, excited by the nearby hot star Xi Persei, which floods the nebula with ultraviolet radiation.

Team work in #astrophotography 🔭📷 gives nice results. Here is M33, a neighboring galaxy combining images from 3 setups. I'm always amazed with its bright blue stars that can be resolved from several million light years away. @kat-astro-bot.bsky.social where's this please? www.astrobin.com/ibi2sb/

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 ?
