Probably my comment will be completely disappeared here ;-)
Bray, it was a great honor and pleasure to have had you on the team for this discovery.
I hope we work together again soon!
Thanks pal! 😁
Not unless I pin it! 😂 Hopefully once the clouds part I’ll find the next one
I also found and discovered, Pickett's Bell around Betelgeuse in 2015. Most everyone who had photographed this area had it in their photos but no one spotted the dark bell shaped ring around Betelgeuse until I shot it up close, spotted it, and called it out in my post. Then everyone started calling it, Pickett’s Bell after my last name. Everyone was stunned when they seen it for the first time even in their own images. :-) For thousands of years we think this dark bell shaped ring is mass being shed and ejected from the massive star as it begins it's death march towards a Supernova. Congratulations you guys for finding this very faint OIII nebula.. :-)
Congratulations!
That's crazy dude
and probably may will find it now in the archives, just nobody was aiming for it directly, and even those who saw it, didn't knew it's something new...
For decades we missed this piece of Andromeda. This really is the discover of the century, I've no words.
Absolute cogratulations. The fact, that it was unnoticed so many years even through it's next to one of the most photographed objects is not only mindblowing, but also inspiring to research the sky for yourself. Imagine how many of such objects there must be in less popular regions of the sky.
Okay, I suspect that someone else has said this already, but talk about hiding in plain sight! This is astonishing. Congratulations. Amazing perseverance. Absolutely thrilled for you and your amazing team!
Congratulations on the discovery, and thanks so so much for making this video. I've seen so much about the discovery in the astronomy press, but nothing in so much detail as your explanations. Really appreciate you taking the time to explain. Keep hunting!
this is incredible, WOW at a loss for words. Amazing discovery and work as always.
Thanks Ryan!
Wow! Congratulations Bray and everyone else on the discovery. This year's APOTY winner for sure 👍 Great video also, very interesting.
Incredible! Congrats on this massive discovery dude!!! This is huge! Just goes to show that everyone can help make discoveries in this field. So motivating! Congrats
That was AWESOME!!!! Congratulations to you and the entire team, a lot of hard work that truly paid off, what an inspiration!
Never thought such discoveries were possible with a wide field of view and amateur equipment. Ridiculously epic stuff!
Just wow! Absolutely incredible work Bray and pals. Just blown away man!
Hi, Bray! Great story and discovery! It is really interesting that many astrophotographers capture Andromeda, and no one had realised there is a nebula until you did!
I recently completed my 24 hours of exposure time on Andromeda Galaxy, and you inspired me to collect even more data on my future targets.
Thank you for the video and clear skies!
Congrats Bray, you really should be proud of your wonderful job for taking part to this astonishing study
Congratulation man! That would have been so exciting to be part of this project. Well done
It was special for sure!
Such a phenomenal find! Congratulations to you and everyone involved!
This is single handly my favourite DSO image so far. Amazing work!
Well done! Amazing! My guess is that imaging it from Tokyo might be slightly difficult :p
Ya never know that hyper star might get the job done if the filter is good!
Absolutely incredible! Well done!
Simply fantasitc work Bray! I think many amateur astrophotographers can relate to dumping images they thought were ruined from gradients, now only to find out that if they had been shooting a wider field of view, they were actually capturing a small part of a nebulous region adjacent to their target. Your super wide field mosaic images give testament to this as well.
Just staggering what someone can do from the comfort of there backyard, truly outstanding and inspring, this is why I love astronomy so much! Well done
Congrats on a fascinating capture!
Fantastic find, hopefully you and this team will continue your survey. Grats on the APOD.
Such a mind-blowing discovery and an incredibly beautiful image to accompany it 🤩 Incredible work from the whole team, and a great video explaining the process clearly and concisely. Thanks so much for sharing this!
That’s for sharing this story. Very inspirational! Bravo!
Fascinating jurney and amazing result!
I just saw your winning image at the Astronomy Photographer of the Year exhibition at the National Maritime Museum in Greenwich. What a spectacular accomplishment for all involved. Congratulations!
So stoked for you bud, congrats to you and the team!
Thanks Ian!
Very cool! Grats to the team on an awesome discovery!
Congrats on the amazing work! Very inspiring!
Congrats to all involved! Such dedicated work! ...& now, I feel I'll be seeing this image replicated ALOT in the coming months/years lol!
With the bad weather and timing I feel like it’s gonna be next august before we see any more images, I’m excited to see some new ones thoufh
Excellent Bray, well done, and great explanation!
This is literally the coolest thing ever!!! So surreal that is what literally right adjacent to one of the most photographed parts of the sky!
Congrats and clear skies, you gentlemen are an inspiration to us all.
This is crazy. Thank you for sharing it with us.
Relly nice and hard work! Congratulations!
Good job! Congratulations to this awesome work!
Congratulations 🥳,
and I wish you more discoveries, and indeed your discovery is the source of the inspiration for all amateurs 👌
Absolutely amazing! Congratulations!!!!
Absolutely incredible work!
Congratulations, this is truly amazing
Thank you for posting this. It's a brilliant discovery.
Waw! Congratulations Bray and the others from the team! Awesome discovery.
Thanks so much!
Awesome, new inspiration 👏🏻
Congratulations. Great work!
Amazing stuff Bray!!
Congratulations! What an amazing Discovery to be a part of.
Great video that's to the point with excellent processing advice and congrats on helping discover this. Looks like I'll be buying new filters now!
Thanks so much! And go for the 3nm for this one
Fantastic work !
Congratulations to you, and all involved! Here's to citizen scientists, and all the amateur astrophotographers out there helping to contribute to our understanding of our universe! You have inspired me, as an astrophotographer, to get back out there and find new things! Clear Skies, and thanks for a beautiful image, and a wonderful discovery!
congrats man that is really cool
Great work. Congratulations!
Congrats Bray on your Discovery!! 😎🥳🎆🎇
That's incredible dude, hell yes!
Congratulations to the whole team 🤩
Great Job Bray.
It's wonderful amazing work
Incredible discovery, congratulations.
Fascinating video and congrats on aiding in the discoveries. I would like to learn more about the Continuum Subtraction processing in PI. You think you can make a small video on that process? Clear Skies!
Great work, what a dream!
The blue vs Oiii continuum process was pretty mind blowing to hear about, such a cool process. It's awesome thinking that this tedious and time consuming process that your team does can help discover tons of "hidden in plain sight" nebulae and how that will possibly impact our understanding of our galactic situation with Andromeda and the universe around us in general. Are you offering prints yet?
09:30 Your concerns about who would get credit for discovery of this oxygen arc over Andromeda are similar to the credit for discovering Neptune. Those astrophotographers who imaged in OIII are going to go back and realize they had something there all along, and maybe kick themselves. The way I see it - anything that is in the night sky is only new to us as humans, not new to the universe.
What you and your team are sharing about this arc benefits the entire astronomy community. I think we should go beyond the obvious 'award mindedness' of such a thing and see if this leads to time on larger observatories to try and discover things about this nebula, such as how far it really is from Andromeda (could it be a line of sight thing and not directly from the galaxy itself??).
I applaud you and the team you were a part of for being willing to spend the time and hours to show that this arc was a real 'thing' and not just an artifact of OIII imaging on M31. Congratulations!!
Yeah in a perfect world it would be nice to be more open about the process, but if I gotta do astrophotography to pay for rent and food you bet I’m gonna keep it on lockdown!
@@astrofalls ya know what I completely understand that approach! I hope for you to make more discoveries with your techniques and connections with professionals in the field.
WOW, Surprise! You and the rest of the team over at Team StDr ROCK 🎸
I just saw your post of this on reddit in r/space and r/astrophotography. Amazing job spaceshuttleinmyanus!
Very interesting and very informative 👍🏻
Absolutely stunning, I may try to challenge myself to get even just a hint of the nebula next time I go to a dark site
With fast enough optics it is doable in one night!
Wow! Congratulations! I won’t look at Andromeda the same way again.
Awesome. Great work
Thanks Tim!
Kudos to your both.
It needs a name and I think it would be a total credit to you both to name it after you both.
Buying this set up
congrats team👏👏👏👏😍
Awesome 👏
Stunning and incredible! Congratulations to all concerned on this discovery and superb image. If I ever switch to mono, this would be a great multi year project given the lack of clear nights here in the North East of England. 👍 Noddy
You could do it it one night if you got like ten telescopes!
@@astrofalls ….be some rig that! 🤣
SO COOOOL!
I always guessed there was always more gases with extra exposure time. Excellent work.
"You are too young to change the world as we see it!"
"Hold my binos..."
Could you maybe do a tutorial on how you deal with the continuum image?
Congratulations! No doubt, your consulting business will be skyrocketing.
This is incredible! Thats truely a really big discovery.
How much exposure would be needed for the nebula in the galaxy itself?
love youtube sometimes for its recommendations and good channels, nice vibes all around :)
Truly impressive work, loved the entire video. I like going deep on deep sky objects, and do have a 3nm OIII filter, but as you say, would not have thought to point it at a galaxy like M31. Very cool. I am interested in how the continuum subtraction in the Blue band is done (and then also potentially in other narrowband emission data sets as well). Is this some sort of a PixInsight Pixel Math operation on processed OIII and Blue filtered data stacks, or is it done in preprocessing, or ??? Can you share some more details on how that works, or share a reference to go look at for more detail on how that part of the processing was accomplished?
Good Job !
Broo .... very good job ... congratulations 🎊 👏🏼.....
I also want to be an astrophotographer like you dude ..
Good job .
Incredible discovery. Congrats !
One questions: did you manage to evaluate, even approximately, the distance between Earth and the arc, so that the scenario in which the arc actually belongs to our Galaxy can be eliminated ?
Thanks!
amazing bro
Congrats for contributing on this discovery. What an incredible image! I've imaged M31 several times, but never seen this faint oxigen nebula. Do you think it might pop up with that amount of exposure time (got a RASA 8 which is very fast), but with a color camera?
If you used a dual band filter with a narrow Oiii bandpass you could pick it up with a color camera!
@@astrofalls Thanks a lot! I have the IDAS NB1 filter, so I think it might work out! Thanks man! Love your work! All the best from Lima, Perú!
Cool image. Just wondering how you ruled out foreground contamination by Milky way and HVCs.
Amazing! I was wonder why you guys use such a small aperture for project of this size? ( beside the focal lenght issue) Why not a 12” or 14” newtonian?
Have they pointed the Hubble at it yet? Let's hope so, nice vid, keep up the great work!
Amazing! Is there a chance you could share how you combine Oiii to RGB data in pixinsight? Is it similar to combining Ha?
Amram et al. published a paper in March, showing that this arc is likely part of a Supernova Remnant 700 parsec distant. Also nice.
thank you 🌈🦋
My first impression was the two blue nebulae are related, so the large one outside was caused by the smaller one inside the spiral arm.
this video is going to blow up mark my words
Amazing stuff. Oh, you said after the discovery but before the announcement you said you'd seen some other photos that showed it faintly (but most likely the photographers didn't notice it). Do you have an example or two? I looked on Astrobin searching "M31" and OIII, but didn't find any. Thanks!
Alex hawkinson or @gazingoutwards on instagram!
Nice man
Just stunning. Could someone please tell me if gas being ionized by ultraviolet radiation is the same same thing as gas being heated because i keep seeing the two explanations used by different people for the same objects.
I was experimenting on Andromeda to see if my 3nm OIII filters are actually working on the MN190 some years ago... I just didn't know it's something new, so I'd rather focused on Andromeda itself, since it was more interesting less noisy :o) (also at F5.6 it was just "something noisy", but now I know how to capture it in it's full beauty)
Bray, your autofocus. Again !
Congrats on the discovery !
I know I know
