My DIY telescope vs $1million Observatory: A Canary Island Special 

thx mate

@@Astrobiscuitthanks mate, for what? An endorphin boost, or ego boost?

@@kayenne221a compliment

​@@kayenne221Somebody's bitter than bitter gourd!

​@@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😂

Agreed

I love aatrobiscuit as well!

Aaaaaatrobiiiiiiickit!

Do you think affixing a small primary mirror with something that might allow a little expansion, say heavy duty sticky back velcro would work?

@@dan14632 Yes that should work; Rory used a similar approach to resolve the issue in his video.

Well said and thx everyone

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!

Aye she's a keeper

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.

WELL SAID!! I can repeat but nahh I can't skip a second of it!! Other youtubers i can skip anything, but for Mr. Biscuit I can't even skip his advertisement telling sections!!

Thx for helping make this happen

Ahh thx bud very much appreciated

Ah mate my dad died 18 months ago

I'm sorry to hear that.@@Astrobiscuit

This is a phenomenal channel!! Unlike any other. Have a great day!!

Thanks!!!!

thanks mate

Why? You know how many big RU-vidrs who sold out to Netflix ended up going back to RU-vid because their audience on Netflix is vastly different from audience on RU-vid?

@@SMGJohn So what we need is a better funding for such youtubers, and a freedom to do what they have always done, but with more assests!!

@@painlesskun3959 RU-vid is entertainment, and entertainment is a business. RU-vidrs who do this for a living should treat it like one if they want to grow larger, thats just how the market works.

Ahh thx for getting one cheers bud

Where do you get your prints from? I'm looking to get my own astro images printed.

​@@ENGAGEXRbuy them from his website I assume

Rouyn noranda loves you brother

Happy Christmas 🎄

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.

Yep yep and I'll try 🤣

Yeah, I'm worried too. It's been 5 months since the last one.

Just amazed you found a solution! I watched this like I was sitting on pins and needles.

well bettty wan't sharper in the end but it was close

His b/w image was not as sharp as their image... you have to compare apples to apples and not apples to oranges.

Thanks

We so nearly screwed up. I filmed the scene at 10 mins and if that mirror had not come off, it would have been a total disaster.

It is a lovely little island.

Glad you enjoyed the episode.
