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.

Merci bien 🙏

Thanks a lot Bernd 🙏

Merci Julien!

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 ?

Sympa comme tout! On dirait une image Mono sur le rendu des couleurs en plus, vraiment chouette (mais je suis pas objectif sur ce point 😊)

There are things that are etched into you as if they were by fire branding....the Berlin Wall collapse, 9/11.....and this....I still remember what I felt when I first heard about that discovery, where I learnt about it, and how (in some science mag bought in a train station). 😍

Galaxie spirale NGC 4725

Voici NGC 4725, une belle galaxie spirale dans la Chevelure de Bérénice ! C'est pas la saison ? Haha oui, ce sont mes photos d'avril que je viens de traiter 😅
N'est-elle pas tout mignonne ?

J'adore @martialrelier.bsky.social ! Bon faut vraiment que je creuse pourquoi BS ne me met pas tes posts en avant alors que je suis le premier de tes fans 🤔

So, how did it go?

Merci Julien! Alors pour la focale l'image est coupée pour me débarrasser de Navi donc en réalité le champ serait plus grand. Je réessaierai un de ces 4 avec ma petite lunette pour avoir plus de nébuleuse autour de Navi (en espérant ce coup-ci qu'elle soit moins pénible la princesse 😅) .

Thanks Bernd! 🙏

The Ghost of Cassiopeia nebula shot with a 130mm Astro-Physics refractor and a dedicated cooled Poseidon-M monochrome astronomy camera. Filters used were RGB Antlia V-Pro filters for the RGB stars, and Baader 6.5nm narrow band H-alpha and OIII filters for the emission lines of hydrogen and oxygen. Narrowband images : 139x120s for H-alpha, 109x120s for OIII. RGB images : 60x30s for each RGB channel.

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

💪

Joli! Tu as bien gardé Navi sous contrôle. De mon côté ma tentative m'a conduit à devoir cropper à mort pour éliminer ce phare 🥲.

That's a nice butterfly 😍!

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.

affiche du film de planétarium "H2O, les états cosmiques de l'eau" à la conception duquel j'ai eu le plaisir de participer

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 is a dark nebula in the constellation of Cepheus. It consists of cosmic molecular clouds and dust blocking the stars. Its form resembles a fish hence the name. But I doubt that anyone verified its smell yet 😅

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.

@kat-astro-bot.bsky.social‬ what do you see?

Beautiful Bernd 😍! The Hyperstar really gives a kick.

On dirait la surface de Pluton je trouve.

Yes! Definitely!

Great shot Bernd! I don't believe I'd heard of this one before. I've added this target to my //TODO list now 😅.

Image of the emission nebula SH2-114 in the constellation of Cygnus. Its structure resembles a dragon hence it’s named the Flying Dragon Nebula. The image was processed in a SHH palette with reddish copper colours.

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.
