Oops. Did it again. 😉 SPHERE at the VLT and Betelgeuse are a great combination for nice results ! Thanks to all the team who contributed to this result, and to the people @eso.org who collected the data.
ESO@eso.org · 2w agoThe conclusion of a century-long quest 😲 Our VLT obtained firm evidence that Betelgeuse, a red supergiant star in the Orion constellation and one of the most famous stars in the night sky, is not alone! 🔭 🧪 1/4

⚠️ La nuit en danger ! ⚠️ La FCC a approuvé le projet Reflect Orbital. Ces miroirs spatiaux vont réfléchir le Soleil la nuit, menaçant la faune/flore et polluant le ciel nocturne pour les astronomes. Un danger majeur pour l'obscurité ! 🤯 Toures les infos 👉🏻 tinyurl.com/ycb7z63j 🧪🔭
It's the Milky Way season, and right now there's a great #astrophotography target, a Wolf-Rayet Star in Cygnus (WR134) blowing away its outer shell.This a composition of narrow band and RGB images shot over several nights.The OIII signal is quite amazing! Where are we @kat-astro-bot.bsky.social ?
⚠️ Une étude de @eso.org alerte sur l'avenir de l' #astronomie au sol 🔭 : les mégaconstellations (SpaceX, E-Space, CTC-1 et CTC-2 etc.) saturent le ciel. Le seuil critique est de 100k satellites. Au-delà, l'impact serait une grave menace pour le ciel nocturne. 🌌 🔗 eso.org/public/france/news/eso2607/
« Au-delà de la limite » : un million de satellites et de miroirs dans l'espace constituent une grave menace pour le ciel nocturne

Hey everyone 👋! I shot Hickon 68 (a compact group of far, far away #galaxies) and the scores of little ones in the background plus some more visible neighbors. It's full of stars and #galaxies! #astrophography Can you spot where this is @kat-astro-bot.bsky.social ?
Hi all #astrophotography aficionados out there! Here's a team work on NGC3718 to which 5 of us took part in. Details over here: www.astrobin.com/cbsw53/ . Lots of faint fuzzies in the background 😍★. The night is dark and full of wonders 😇. Can you solve this please @kat-astro-bot.bsky.social 🙏?
A quick processing of the beautiful Sh2-124 nebula (showing part of the larger Sh2-124 region) from last Saturday’s imaging session. 🔭 About 70×180s subs. Thanks to @ltno2.bsky.social for the great tip on boosting the Hα emission through the luminance channel.
With my #astrophotography buddies Jeff, Alex, Franck & Stéphane we stacked somewhere close to 1000 frames per LRGB channel on Keenan's system (2 interacting galaxies) + a ton of galaxies in the bg. Can you solve this one @kat-astro-bot.bsky.social ? Technical details: www.astrobin.com/ewm0jd/
🌌✨ Clear skies in Normandy tonight! ☺️ 🔭Targeting SH2-124, a beautiful emission nebula. With the C8 EdgeHD, I’ll only be able to frame the central circular portion. It’s extremely faint, even 180s subs barely reveal it. Let’s see what the stack can pull out! June nights are so short! 😅
I revisited the processing of NGC 3718 🔭 with the aim of making the galaxy’s “whiskers” more visible 🙂! The background could be improved, but I still prefer this result over my previous processing.
JDS@jdsoubeyran.bsky.social · 3mo agoThere you go — 57 × 240s on NGC 3718. 🔭 Still needs more integration time, but not a bad result at all. Also visible in the picture NGC3729 and loads of little galaxy’s… ☺️

NGC3718 tonight (weather permitting at last…😬) a beautiful barred spiral galaxy located 47.8 million light-years away, in the constellation Ursa Major. I adjusted the framing to include NGC3729 — note the lovely group of tiny galaxies to the right of NGC3718! Fingers crossed for tonight!🤞🏻🔭
@letripode.bsky.social Bonjour les éditions Le Tripode A quand la version eBook de Gen aux pieds nus ? 😉
A bit of last night's Moon. The prominent crater near the left, above the terminator is Maurolycus, its peaks and floor nicely lit here.
Night / Day ! Still testing the #Seestar S50 🔭, which has been giving me quite a few issues. I’ve noticed a problem with my unit: during my deep-sky live stacking sessions, I’m getting a very high frame rejection rate — often exceeding 50%...
Quick processing of M106, this galaxy is stunning! Captured during the night of April 18–19 🔭, total integration time of 4h20 (66 × 240s subs), L-Pro filter Oh, note that I'm struggling with BS compression, many pixel artifacts when I upload the image... 😡 Maybe a background issue ?
Votre belle (magnifique) image de la semaine (de l'année) vous est présentée par cette équipe d'astram pour laquelle il faut un nom ! Bien joué à vous!!
Martial Relier@martialrelier.bsky.social · 4mo agoPetite fierté du jour : je vous partage un travail commun avec les copains astrams : @alrouen.eurosky.social @ltno2.bsky.social @jdsoubeyran.bsky.social @vbioret.bsky.social et Vlaams59 (abonnez-vous !) sur M106 et son entourage avec plus de 63h de poses cumulées ! 🔭 1/3

My friends @ltno2.bsky.social; #Vlams59; @vbioret.bsky.social and @martialrelier.bsky.social are currently working on an amazing image of M106! It made me want to point my telescope 🔭 at this target too! The weather is unstable, so I hope I can get enough subframes tonight…
🔭 🧪 À noter dans vos agendas
Josselin Desmars@jdesmars.bsky.social · 4mo agoDans tout juste 3 ans, l'astéroïde Apophis passera à seulement 31000km de la Terre. Ce sera l'occasion unique d'observer un astéroïde à l’œil nu puisque Apophis atteindra magnitude 3. Voici à quoi ressemblera son passage express dans le ciel du 13/04/2029 vu depuis la France #Apophis #NEA
#M101 #Galaxy Total or 3 nights (2 nights with L-Pro filter and 1 with L-Ultimate for H-alpha layer. About 13 hours total on this target)🔭 There’s still quite a lot of hot pixel noise in the L-Ultimate master after WBPP, I’m trying to figure out the cause, but overall the result is quite satisfying.
Processing of the images taken on the night of 5–6 April using the L-Ultimate filter for an H-Alpha master. 🔭 The aim is to reveal the nebulae of M101, thx @ltno2.bsky.social for your help. (To be continued) #pixinsight #astroohography #Astronomy
Clear sky tonight in Normandy; I’m continuing with #M101, adding H-alpha (Ha) sub-frames… ☺️🔭✨ #Astrophoto #Astronomy

Corey S. Powell@coreyspowell.bsky.social · 4mo agoThere is a full universe behind that wonderful new Artemis II "Night Marble" view of Earth. Here's a breakdown of the stars (and one planet) in the field of view. Look at us! Just a planet hanging out in space. Annotation by Rodrigo González Peinado. 🧪🔭
Looking pretty good so far! Just finished the pre-processing stage... Full processing to follow. This galaxy is actually huge!" 🔭 We’ll see how it turns out after processing... M101 feels a bit cramped on my IMX533 sensor... #prepossessing #pixinsight #astrophotography
The new drive... with all my M101 lights and flat frames... I've made a double backup! 😉 New processing next week! 🔭
