@@kayenne221 for being nice and appreciating his content his effort into each of these extremely enjoyable videos ❤ And if you think Rory has ego then I think you have a brain of a pig😂
Simply brilliant story telling and great effort which all paid off in the end with that stonkingly good M33 image! So many twists and turns; my heart sank when the mirror was glued to the cell ! I've made that mistake before and the temperature expansion between the glass mirror and metal mirror cell causes astigmatism. Very well done to Rory for getting it fixed and to all involved in making these epic videos happen. Until the next exciting episode!
Yes. An other way of gluing a glass mirror to an aluminium support while still avoiding stress occuring in the glass causing astigmatism, is to have leaf springs in between glass and aluminium support. Just imagine 3 leaf springs (every 120°). Leaf springs bended 90° so it forms a lip that can be glued onto the glass. The other end of the leaf spring can jut be screwed onto the support. This way, since a leaf spring "locks" 2 translations and 1 rotation, using 3 of them at 120° is able to constrain all 6 DOF's (degrees of freedom: 3 translations, 3 rotations) without inducing stress in the mirror.
Hey, at least he had the foresight not to use epoxy glue or other glue that couldn't be undone without force that would hurt his mirror. I call that a successful experiment!

The CTE of aluminum is much higher than glass, but its elastic modulus is similar. That approximately torques the mirror as the aluminum cools differently than the glass due to drastically higher thermal conductivity. Richard Berry recommended a quarter-thick layer of silicone. I use a reserved set of steel skewers.

I have been waiting for so long for you to upload, I cant express how happy I am. Your videos made me start with astronomy! I bought my first 8 inch dobsonian 2 months ago and I am already addicted to this hobby. Recently I made calculations and CAD design to build my first euatorial VNS platform which will make planetary imaging much easier. I wish you clear skies in 2024 and many videos to come, greetings from Slovenia.
What a drama!! What a video!! What a photo!! The A2 is going to look amazing up on the wall…. And anything to help fund the next instalment! Thanks Rory for all you do - one of the most entertaining channels on YT
Outstanding effort and an absolutely epic shot! Tenerife is a very special place to me, I have been up the mountain stargazing many times and can attest to the mind blowingly amazingly clear skies up there! I have never seen stars like it and to be able to clearly see the milky way with the naked eye with clarity is unreal. Brilliant episode as always and big shout out to all those that made it possible. I have just purchased a print and can't wait to get it framed and on the wall!
Looking closely, you could see more star detail in the observatory's shot, but it's by a very thin margin. I think you did really well with your setup, particularly given the last-minute modifications. I'd definitely be interested in seeing you go back with a larger scope to see if you can close that margin of detail. It'll be tough to travel with a quality scope that size though...at least by plane. Maybe take a boat? Thanks for sharing this journey with us. Really enjoyed it.
He has to get a proper case for it and board it on the plane as fragile and special travel goods, which means it will be handled better and put in a different place on the plane, they deliver it to you personally after the landing, it costs more, but the price of beating a million euro telescope, is well, its priceless.
Fantastic video, I love the journey you take us on, through all the ups and downs. This is why we love Astrobiscuit (and Pink Bunny) - I hope you can do more big projects like this! How about a southern hemisphere trip, there has to be something down here worthy of a challenge!
We can still say that Betty won this competition in her own class. The photo looks great. It is sure to be an inspiring result for amateurs! I agree with Bunny. The next mission is obvious! You have to do it! Happy new year to you, the whole team and your family! 🎄🎉🎊

It is just something that I love, You document and put together the contents in such a way that caters to my taste, I can't describe it!!

Best Horror/Adventure RUclips video I've seen in a while, insane shot, insane... Also legendary moment that you mounted the steel plate with patrons names on the telescope 😢
Honestly netflix need to give you a show, the way you deliver the story and the exciting way you talk about astronomy is out of this world, pun intended
Why? You know how many big RUclipsrs who sold out to Netflix ended up going back to RUclips because their audience on Netflix is vastly different from audience on RUclips?
@@painlesskun3959 RUclips is entertainment, and entertainment is a business. RUclipsrs who do this for a living should treat it like one if they want to grow larger, thats just how the market works.
I started watching you videos for a week and immediately subscribed! and one of the reasons is that you're very entertaining and do not just make anyone feel broke... anyway, I would love to see you give a really short review of f70076 newtonian reflector in your 100 pounds series
I never thought I would randomly find such an amazing channel. The music does your story telling justice. Now I am thinking about buying a telescope :D
Mission accomplished Astrobiscuit and what a nail biting video thought it was all going to end in tears but with your knowledge and intuition and help from your team you succeeded.
Such an amazing video, the fact you have always shown when things go wrong means we all genuinely don't know what the outcome will be. Found the channel about 6 months ago, have watched every video and now am inspired to stargaze myself with a nice new 8 inch dob waiting for clear skies.
Bro where are you? You're my favorite guy for this stuff. There was supposed to be a pretty cool planetary allignment just before sunrise june 3rd 2024. I bope you recorded some stuff and upload it soon. My 4 uesr old and i just zone out on your videos. He's amazed with space and planets.
A 14 inch telescope would have just a bit less than half the resolution of the professional scope. Think about it. If the professional astronomers could get the same resolution as their $1 million telescope for $10,000 or $15,000 they would have already done it. Aperture is inescapable as the arbiter of resolution unless the steadiness of the atmosphere is terrible. And the laser based adaptive optical systems on some larger scopes can adjust for atmospheric scintillation automatically in real time. But imagine this: undebatable spiral structure in galaxies wasn't definitively shown until 1917 with the 100" Hale Telescope on Mount Wilson, California. AstroBiscuit doesn't only get spiral structure, but virtually dissects M33, a more difficult galaxy than M51 that they used in 1917. It is true that Lord Rosse's 72 inch Leviathan showed him spiral structure in M51 in 1845 but he had to sketch what he saw. His findings weren't accepted by the scientific community as definitive. They were very busy debating whether the "spiral nebulae" were inside the Milky Way or external structures. AstroBiscuit's photo of M33 is better than any from the 200" telescope on Mount Palomar from the 1960s. Their limitation was very grainy black and white film with a low exposure latitude. Telescope resolution isn't always the only game in play.
The 2h processed shot is absolutely amazing and I'm pretty sure that the professionals at the observatory will agree. Yes, the 1h unprocessed image is not as sharp as the one from the much bigger IAC80 but it's still impressive as heck. You've pushed the limit of what's possible at that size, so next step: go bigger. But if you can: do make a video call with the folks and get their reaction to the results of Betty.
Fyi, we mount all our space telescopes with RTV on the kinematic PM mounts which glue to the backplate of the mirror. Any adhesive will have cure shrinkage and will put strain energy into the PM but the RTV flexes enough to keep it very low. This is pretty much a standard used for 50 years on weather satellites, Hubble, Ikonos, Worldvview, etc...
Fantastic video and was great when you went abroad and met all the people from the observatory who were shy but enjoyed being on your video and to see the stuff you make at short notice is amazing. Keep up the great work 👍
Mate, I’ve been struggling with pinched optics with triangular stars for months, your double sided tape trick solved it ! Kept the clamps in place in case the tape gives way, but backed off 1mm from the mirror surface and it’s the first time my reflector has had circular stars ever. You’re a legend.
This is intriguing and fascinating for novices like me, makes me want to get up and just explore the night sky. I've never seen content like this and this production value is insane. You are criminally underrated.
Incredible! It's absolutely mindblowing how such a small telescope can beat the huge observatory beast and even more - its in color! Can't wait for the next iteration of the Betty, the Betty 2.0 - 2 times fatter mirror, 2 times sharper, 4 times coller results ;D
great video, great work, as a regular visitor to the canaries, I know the excitemen of seeing the night sky - we're more often on La Palma. Not yet moved there (ha) so cannot offer you any accommodation. Looking forward to seeing the next video. We'll be over there day after tomorrow.
I know next to nothing about astrophotography. However, the idea that the everyday working guy could build something at home, that is portable enough to take on a plane. Have it come as close as it did to a huge professional observatory is not just beyond impressive, its mind boggling. The photograph you took was just so stunning, i can see why you have the love and passion you have for this. It blows my mind that i was looking at a galaxy 3 million years in the past. WOW! Just simply WOW!!!
Such a fun watch, amazing work! I know the feeling of running out of time and being down to the wire with the shoot fast approaching...there's no better high than stressing to get everything done and it working out. Bravo and can't wait to see what's next!
Holy cow! What a great video, and what a fantastic bit of DIY engineering to get Betty to the finish line! Hats off to you, Biscuit! This was an awesome David vs Goliath showdown.
Having only ever had a 4" reflector, and making "Awww" noises whilst looking at Jupiter. You've rekindled my interest, and given us a reason to believe. Thanks mate!
You sir are the astronomical Richard Hammond, proper entertaining, funny and intuative, Nice one ....... I have recently got my first telescope and then found your channel. I watched one video and now I can't get enough so had to subscribe. Nice one .........Brother.
Your results are incredible! Congrats to all involved👏👏 As a very casual / occasional night sky viewer, this whole concept is a bit mind blowing. I find it interesting that the professional gear isn't using newer cameras. I wonder if upgradeability will change in the future.

Oh man I was waiting to see this for a long time! So glad that Ceri also could make it and almost see it in action.
I just watched this for the third time... Best whishes for the new year, and looking forward to new Astrobiscuits, nice music, and a cunning rabbit.
Such a fun watch, amazing work! I know the feeling of running out of time and being down to the wire with the shoot fast approaching...there's no better high than stressing to get everything done and it working out. Bravo and can't wait to see what's next!
I am so glad you were successful!!! I’ve been following this epic adventure all along. Merry Christmas and best wishes for the new year!
More tension and excitement than a roller coaster. Not quite the win, but a valiant effort and a stunning image. Well done Betty and all involved.
Production value top notch as always. I could watch your videos all day!
@Astrobiscuit what a phenomenal effort! That photo is amazing...
i recently stumbled on this channel in my feed and i am amazed about your devotion and skills (amateur) is out of place you are a Pro !!!!
The upper lever of Canary Islands looks much like how Las Vegas looks :-) Thanks for another great video!
Holy cow! What a great video, and what a fantastic bit of DIY engineering to get Betty to the finish line! Hats off to you, Biscuit! This was an awesome David vs Goliath showdown.
Having only ever had a 4" reflector, and making "Awww" noises whilst looking at Jupiter. You've rekindled my interest, and given us a reason to believe. Thanks mate!
😁
You sir are the astronomical Richard Hammond, proper entertaining, funny and intuative,
Nice one ....... I have recently got my first telescope and then found your channel.
I watched one video and now I can't get enough so had to subscribe.
Nice one .........Brother.
What an adventure, under such brilliant skies .. and an amazing image from Betty
It's insane how the qualities are so close to eachother, honestly unbelievable.
Bravo that man. Lis all the supporters who made this possible. Betty is a fantastic piece of kit. I hope you test her again and again.
Your results are incredible! Congrats to all involved👏👏
As a very casual / occasional night sky viewer, this whole concept is a bit mind blowing. I find it interesting that the professional gear isn't using newer cameras. I wonder if upgradeability will change in the future.
From NH, USA here. Been following for sometime bow and you never fail to amaze, and entertain. Much love.
Thx bud
Thats awesome. One of the most beautiful astrophotography pictures ive ever seen
