Noyeu joel à vous huéhuéhué

Non mais regardez ça. Ces traits bleus passent sur la gauche derrière un nuage de poussière, on en voit un peu a travers. C'est BÔ!

J'aime bien me rendre compte de la taille de ces paysages en me disant que la terre c'est un petit cailloux collé à une etoile du champ.

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?
Sh2-200 is an old and large planetary nebula and therefore it’s very faint. Its shape and streak like structures resemble a bear claw hence the name Bearclaw Nebula is quite fitting. Sh2-200 is located in the constellation of Cassiopeia at an estimated distance of about 3,600 light years away from Earth.

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!

✨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.

what do you see ?
#blueskyartshow #sky
A deep-sky astrophotography image showing the Horsehead Nebula silhouetted against a glowing red emission cloud in Orion. On the left, the bright star Alnitak creates a strong flare and scattered light, contrasting with the delicate dark shape of the nebula and surrounding wisps of gas. The scene is detailed and colorful, captured with an A7S and a Newton 130/900 telescope.

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?
VdB 14 and VdB 15 are a pair of beautiful reflection nebulae in the constellation Camelopardalis. They are about 2600 light years away from Earth.

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
The Sun shot in H-alpha using a monochrome Zwo ASI1600GT camera and a Lunt 60 THa solar scope. This is the combination of two overlapped images: one overexposed to show the prominences and the other one to show the chromosphere details. False colors were used to render each of those overlapping images.

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 ! 🔭 🤯

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 ?
M82 galaxy showing H-alpha jets being expelled from its nucleus. This is a detail from a wider field of view given in this post : https://bsky.app/profile/ltno2.bsky.social/post/3m6ajatkmzs2e

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 ?
M81, M82 and NGC 3077 galaxies shot from a backyard with an Astro_Physics Starfire EDFS 130mm refractor and an PlayerOne Poseidon-M monochrome camera using LRGB and H-alpha filters. M82 shows hydrogen jets being shot out of the nucleus of M82.

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?

M33 the triangulum galaxy. This image combine images from three different amateur astronomers for a total of approximately 17 hours of integration time. Details are on Astrobin : https://www.astrobin.com/ibi2sb/

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