We discovered a HUGE supernova remnant in Cassiopeia

This video tells the story of the discovery of SNR G107.5-5.2, the Nereides Supernova Remnant in Cassiopeia. Currently, the largest known supernova remnant to ever be discovered by amateur astronomers.
This nebula was discovered and photographed as an international effort alongside my friends Marcel Drechsler, Yann Sainty, Nicolas Martino, and Richard Galli. We found and photographed this entirely with telescopes available to consumers.
We hope you enjoy the video and the discovery, full resolution images can be found here: www.astrobin.com/towmdb/

My friends, what a great and unique collaboration! It was an honor to me! 😀

Hammer 🔥

[@AstroDragon33]

Fantastic work in Photoshop. Your a wizard and an inspiration ❤️🔭🌌

[@luboinchina3013]

THE NERDS NEBULA. That's how it should be called.👍

[@lookspacethings]

The Supernova Remnant is beautiful! We amateur astrophotographers know how much work one has to put into it to make such discoveries. Congratulations Bray and all the people involved.

[@corn_enthusiast]

This is awesome, Bray! Congrats to you and the team! 👏

[@deep_space_dave]

I saw you image on Astrobin, amazing! Congrats to all of you! Clear Skies!

[@astrofalls]

Thanks Dave!

[@shubhamcweb]

Amazing discovery, awesome work!!

[@leoncorns1450]

I really loved the video. Well done with the name. It just goes to show what's possible by amature astronomers.

[@LogansAstro]

What an amazing discovery by the team. Congrats to you all. Stunning image.

[@astrofalls]

Thanks Logan!

[@cdz9400]

Can't wait for this to premiere!

[@Hughejazshole]

Now this is pretty damn cool!!! Well done guys!👏🎉👏🎉

[@epielanonimo]

Congrats on tomorrows APOD! Such an incredible discovery.

[@GuillaumeCannat]

Bravo à toute l’équipe pour cette découverte exceptionnelle : vous avez ouvert la porte du rêve 😊 merci !

[@grandourseplanetarium2420]

fantastique découverte :) Bravo à toute l'équipe et quelle belle collaboration pour un résultat époustouflant !

[@astrocatinfo]

Extraordinary work!!

Congratulations Bray!

[@Arcteek]

Good job guys!

[@peterlaubscher3989]

Congratulations - what an amazing achievement!

[@ruthlessrog1]

This is insanely gorgeous! Well done fellas, this is def gonna be a historic image

[@astrofalls]

Thanks!

[@mikeharden7904]

An amazing discovery Bray and an inspiration to all of us as astrophotographers. An almost indescribably beautiful image. Congratulations to all of you. I look forward to what the scientific (astronomical) community has to say about it.

[@astromarso]

Outstanding! I love the whole story around this discovery! This team takes astrophotography to the next level! Thank you for the inspiration! Can't wait for the next object to be found from you guys! Herausragend! Ich liebe die komplette Story rund um diese Entdeckung! Dieses Team bringt die Astrofotografie auf das nächste Level! Danke für die Inspiration! Kann es kaum erwarten, bis ihr das nächste Objekt findet! 🤩

[@ronanhunt88]

So amazing guys!!

[@astrofalls]

Thanks man!

[@JesusMVargas68]

Fantastic👏👏 Congratulations 👏👏👏✨✨

[@mistaskate8715]

Spectacular!

[@itskraz3yivanhere850]

Awesome - great video. After finding yours (and others) discovery with M31 and its lovely blue companion I decide as a recent beginner to jump in the deep end. 1st up is attempting to replicate any of that around M31 on a smart telescope from vaonis (I'm mad and up for a challenge!) went with an Altair 4nm Sii and Oiii filter - just need many hours of imaging to see if I get anything or not. 2nd - I have a telescope live account so am randomly looking for Oiii stuff from some fav targets of mine (rolled a dice!) Keep up the great work.

[@astrofalls]

Thanks! And happy hunting, even if nothing shows up remember it is always worth it!

[@itskraz3yivanhere850]

I know its so fun!@@astrofalls

[@afryhover]

Well done fellas 👍👍 I've been trying to get my deep-imaging crew together for a while now. I went really deep on M31 with Ha, got an APOD in October 2022, then you guys got the APOD a month later, I was like dang I need a crew! 😂

[@fazergazer]

Nereides is perfect!❤

[@wesleydonnelly2141]

is it just me, or can other people see, from 09:59 to roughly 10:14, a new candidate for "Thor's helmet"?? I also saw, in the red dust immediately to the right of the helmet, what appeared to me as a human head, face and neck, which could also be interpreted as a face with a mask, particularly those Masquerade masks you see at parties?? Maybe it could be called "The masquerade nebula"?? 🤔 Awesome work once again Bray! You're getting really good at finding these as yet unknown objects/structures in space!

[@EricMilewski]

wow, speechless 😯 Why can't more people just get along

[@maximel.4359]

Félicitations 😊

[@KopLamp]

Incredible discovery. Curious if I would be able to capture it too with my modest equipment from a very cloudy Netherlands. One tip as one KZbinr to the other; You might want to make those Zoom call recordings stereo. Watching this video with headphones on is a bit annoying.

[@astrofalls]

With fast optics and dark skies, it is certainly possible to get something, but this is faint faint. And I’ll keep this in mind for the next one!

[@AstroDragon33]

Can you add a full list of equipment used, filters, camera/s scope etc? Such a wide object! Wonder if rasa or hyperstar would be up to the task for faster imaging or if it creates a hinderancr. Great work, im working on my own discover now. You Rock Bray!

[@Darren-vf2qw]

Follow the Asrobin link in the comments for full description.

[@astrofalls]

All this is on our astrobin image in the description! A RASA would definitely help image this beast, especially with a mono cam

[@kevinkorslick8670]

Mutual aid for the win again!

[@AsVal6]

Let's gooooo🎉🎉

[@dougiesmart1623]

An amazing discovery there. Can you superimpose this amazing nebula against the Cassiopeia constellation so I can get an idea of exactly where it is? I was also wondering if you have any idea what magnitude this incredible object is? Keep the great work coming 😊.

[@astrofalls]

Check our astrobin image! It has coords and the widefield reference. Not sure of the magnitude, but it is faint!

[@einzwei3364]

We need more of such mind blowing beauty to put our own little existence into a greater perspective. People who realize and acknowledge this perspective may then start thinking on how insignificant humanity and its problems are in this large open void. Better get our act together and engage into creative constructive activities than all the unspeakable destruction and chaos we are causing to ourselves and our microscopic yet unique place here on earth.

[@bestytubeplaylists]

Hello Bray falls!

[@bestytubeplaylists]

Has anyone in history ever captured a real image of all 7 planets aligned with one another?

[@bing.trigger35]

Try capturing gaia bh1 the blackhole

[@fazergazer]

What is the brightness compared to the tiny squid I wonder ?❤🎉🎉

[@astrofalls]

Good question! I think they may be roughly similar

[@hunter133official]

We have like 3 objects in the Falls Object Catalogue (FOG) already! I smell new age Messier!

[@DavidShaneTrueCosmology]

Since nobody witnessed the super nova event, how do you know thats what caused or created it?

[@astrofalls]

We can tell by the filamentary morphology! This is a dead giveaway of a supernova

[@RandyLe-cb2eb]

If u discover it. How far was it ??

[@CatholicSoldierX]

12:00 and 12:12, Am I seeing demons? At 12:12 it looks like some demon writing something

[@Cekpas]

Why you use a deadcat inside house?

[@astrofalls]

It helps with my Ps popping

[@rickcrume739]

can this nebula be pinpointed for an young amateur astronomer

[@PetraKann]

What are the 3 most important discoveries you've made using your astronomical equipment?

[@astrofalls]

of the public ones, the nereides snr, the lightning bolt snr, and falls 8 in phoenix

[@PetraKann]

@@astrofalls excellent
