Don't use Windex, Windex is only for Regular Plain Glass NOT for Primary Coated Mirrors. For my Mirrors Multi-Coated , I only use top "Photographic Lens-Mirror Sprays specifically formulated for Multi-Coated Lenses and Mirrors, I Purchase it from my Photographic Camera Store Specifically made by Opticians for Multi-Coated Lenses and Mirrors , I then wipe with only Photographic Lens-Mirror Tissues also purchased at Photographic Camera Retailers"! Your Windex method has just reduced Reflectivity!!
This is awesome stuff. This is what man-kind should concentrate on. Not building churches and nonsense rituals of religions. Science is the most important endevour imaginable. Its astonishing that we have all this knowledge and still superstition rule so many lives.
With Chili's location on a major fault zone, it must be a fragile operation no matter what is being done. Has anyone heard if the last large quake caused any calibration changes?
Ad Meijer Aluminium has a constant (very high) reflectance over a large part of the spectrum (from UV to IR, including the visual range). And, this might suprise you, an aluminium coating is actually very durable because it always has an utrathin protective cover of aluminium oxide. Aluminium oxide is one of the hardest and materials we know of. You may know it as saphire.
Yes but our methodology is flawed. While not reasonable or even feasible, we are using our mere devices to peer into their clean room setup. Now taking this into consideration, it's not impossible that every person that sees that dust particle, actually has it as a defect in their screen or miniscule scratch. We can't rule this out. And because of this, I am required by law to say that I can't confirm or deny your observation, but I have taken note of it.
+LordFazza There is limited space on top of the mountain, and to avoid light polution and so on, only the bare necessities for telescope operation are located on the mountaintop. Also, the area has several mountaintops with telescopes located on them, and the mirror maintenance building serves all of them.
maybe this is a dumb question, but why don't they just build a mirror maintenance building right next to the observatory building? wouldn't that ultimately save a lot of time and effort transporting it to be maintained?
Why? Because that makes too much sense - this is all from grant money most likely, so the objective is to make it as complicated as possible - I always wondered why, in the 21st century, they can’t make a reflective surface on Mylar or some other thin flexible material - why does it even need to be a zillion pounds? What about a carbon fiber frame? None of it makes sense to me.
You think you're so smart. There's a lot of variables that you are ignorant of. I'm ignorant of many of them too. but I at least know enough to know how much more ignorant you are and stupid too. the objective isn't to make it as complicated as possible. That's pure stupidity to think that. Why don't you spend some time informing yourself instead of foolishly acting like you already know?
I'm having a hard time figuring out what the male and female narrators' accents are, especially the woman. She sounds like some strange cross between and American and and Irish accent, and the guy seems mostly British, but not quite. Can anyone place their accents?
@dfan If the mirror broke, all the workers will get 7 yrs bad luck! I didn't wanna see it break but I did wanna see what would happen if someone unintentionally put a tiny tiny scratch on it and then walked away pretending it never happened. : )
I never understood why they can’t make a mirror on Myler or some other thin material - why does it need to be on some insanely heavy thick glass? It’s just a reflective surface - guess I just don’t get it …
Take some time to learn about telescopes. a thin mirror would flex too easily. you'd never get an image in focus. do you even know what mylar is made out of?
Never really thought about the cleaning process of a mirror. Interesting!
all this work just to get some pictures of the stars, that just proves hard work pays off
I'll be more than happy to have the secondary mirror .
Hey btw thanks for reminding me, after three years of recovery from the heart attacks last time I watched this now I had new one hahaha...
8:21 can you imagine if he sneezed?
I'll bet there would be some fascinating vocabulary utilized by multiple parties.
Wow, what a process!
They need to spice things up and do this during the super bowl half time show
I almost heart attacked watching this.

have you considered joining a local astronomy club? you'd be able to do exactly that. show people the universe by hosting free public observations.

Why use aluminium when you have to change it out once a while ?
would paladium or platinum not be longer lasting ?
If you get an answer, let me know.

Ok thanks
Cool.
What accent are you guys masking? It's very bizarre. Like Swedish making fun of Canadian or something :P
Anyhoo.. good science, keep it up.
I love astronomy.
@trevelocita:
I'd blame it on the New Guy. Everyone uses the New Guy as a scapegoat
Very cool.
Sooo interesting!
cool. i've always wondered how they did that. thanks for sharing;
anyone else notice the particle of dust on the mirror while buddy is testing the reflectivity

This must be so expensive, how did they get the funding for this type of thing when people are always arguing about the cost of stuff.
why isnt the mirror maitenance building right next to the telescopes?

Altitude sickness.
Soo... Did a Bird take a shit on the Mirror as it was passing by or what was the cause for the need to clean/resurface it?
Ingeniería en estado puro!
how menny times dit she says mirror :-D hehe.. but thats fantastic!! 5 stars ***** !! Thanks !!
wow, sounds like a lot of trouble. but its all worth it.

@@ssnoc Thanks and wow I asked this question 9 years ago. Lol

Am I bad for wanting to see what happens if that mirror broke :(
Wow.
thank you
:)

Ultra pure water (and chemicals)... lol
is that the only telescoope wit that mirror?

Is this telescope stronger than the Hubble telescope?

como me gustaria trabajar ahi...
it looks like a gigant laserdisc xD thats many TB of storage :P anyway , good video :D
I'll go walk around on the mirror with a rag and a bottle of windex ....for half the price.
How often they have to do this?
That's a stressful job!
how often is this done?
8 nanometers of coating, wow...
+ if you break it you get bad luck!
Where are they getting those commentators anyway? They sound odd :-/
how often?
I thought, you only can use a Clean-ex...lol
Space #Freebooting. Goto ESOcast.
ultra pure water? lol we cant even have that in our drinking water :P
the murrroerr
i want that job... lol....
@puffrooster lmfao
Don't talk about POOland like that.
why are we pathetic?
haha, as a swede i see the resemblence
@calebp9503 ah ok
murrror
aluminium... -_-
yes, it makes you a terrible person :)
Ridiculous!
Weeeeeeeeee first
Super annoying how the guy speaks gahh
how you criticize someone for how they talk is super annoying. people like you are the worst.
