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 ? 😇

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.
On the Factor Fexcectorn and autism bicycle AI slop study: I got an answer from Springer Nature this morning that this scientific paper will be retracted! 🧪

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 ! 🔭 🤯

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?

I tracked this dramatic area in 'Orion's Belt' for nearly 8 hours to capture the light for this photo.

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 🤓?

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.

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.
