Inside the WHT - Deep Sky Videos

[@FrancoCiminoPrado]

I really get exited every time I see footage or someone talks about the VLT or ALMA, I'm from Chile and those are two of the things that make me proud.

[@donloughrey1615]

I like the 'eyepiece story' . I still look through my 4.5" reflecter while imaging with my 10" sct. The eyepiece is why I got into astronomy in the first place, I'd hate to lose that. Thanks for posting.

[@PhilAEG]

WHT has a 4.20 m Cervit primary mirror, a 1.0 m secondary mirror and a 0.62 by 0.43 tertiary mirror (elliptical shape). First light was in June 1987 and they looked at Messier 64... Thanks for posting DeepSkyVideos!

[@DeepSkyVideos]

Not only is it there (and shown in this video during the horizon pan) but we have done a whole video tour of that one too.. we posted it a while back!

[@dawsonoo7]

Yes I saw it and am looking forward for the next one, thanks for the reply Brady!

[@DeepSkyVideos]

thank you - we'll have more from the WHT soon

[@DeepSkyVideos]

More about the WHT, including its "adaptive optics" is coming soon!

[@DeepSkyVideos]

actually from what I understand (not being an astronomer of course) there is much to be learned when the planet goes behind the star too (ie: secondary) and these are measured just as carefully.

[@DeepSkyVideos]

we've done one video on that (I assume you saw it!?) and another one is likely tomorrow!

[@DeepSkyVideos]

cheers... there's more astronomy on my sixtysymbols channel too (with some of the same people in deepskyvideos)!

[@13someguy13]

Informative as always Brady. Also, Dem Legs!

[@SuperShadowP1ay]

Kinda depressing these videos have mostly been forgotten. They're still top notch 8 years later!

[@GavinRemme]

I’m here binge watching in 2022! Loving them. I hope they’re not forgotten.

[@Dannoduckhead]

I get to go here in November! Super excitement!

[@DeepSkyVideos]

that's an idea! not really sure what our future is beyond the Messiers... There are certainly plenty of options... And even before we finish the Messiers we'll look at a few other bits and pieces.

[@igext]

Could you make a video where one of the professors describe how such telescopes function in detail ?

[@Mastertim2006]

very interesting video, thank you brady! waiting for more!!

[@DeepSkyVideos]

there's more coming!

[@t38ip]

Take a look at DeepSkyVids Exoplanet Transit. At 1:39 you will see another angle of these structures. Some kind of radio telescope maybe? The angle in this vid your looking right at the dish.

[@DivingDeveloper]

Thanks for posting this, it's incredibly interesting for those of us with teeny-tiny amateur versions :) What surprises me is that this telescope appears to be Alt-Az mounted whereas objects travel through the sky in an apparently equatorial motion. So if the telescope tracks in Alt-Az, won't the view appear to spin? Or is the telescope slanted on a wedge or something? Please let us know!

[@forton615]

I would assume they could spin the camera or "instrument" in the opposite direction to compensate that.

[@DeepSkyVideos]

if they do, that'll be a great place to visit and make a DeepSkyVideo!!!!

[@DeepSkyVideos]

rightly so... very cool!

[@Funkmastabuzz]

Love the videos. Will u be doing any follow ups on the 3 things you mention at the end.

[@Meb8Rappa]

Dear DeepSkyVideos Could you make videos about all the 88 constellations, and their deep sky objects, after you finish the messier objects?

[@wslogue]

But just how big is the senser ? Is it the size of a tea tray I love the close view of the mirror but when do we see the rirrow.

[@dronexmail]

Humbly fascinating.

[@dawsonoo7]

any more news on that supernova in M95 ?

[@cats_know_everything_about_you]

01:18 what are the strange pixellated objects in the foreground?

[@bullamarta]

ive heard that when a planet goes behind its star the light still dimms a bit because of the light that is reflected off the the planet is lost.they reckon they can detect that loss,truely amazing

[@sugnaangus]

You sound so exited in the first few seconds of the video, Brady! Hard to blame you!

[@Funkmastabuzz]

can anyone apply for use of the telescope (if u know what ur doing) or do u have to be with a uni?

[@Viracocha711]

What are the two circles that appear to be pixels at 1:15??

[@KeenanTims]

What's that noise that sounds like an MRI inside the dome?

[@TheCrAziEsTSKiiLL]

i love you vids brady

[@Shoyrou]

At the bottom at 6:20... do I see yuki nagato from suzumiya haruhi? (url: images.wikia..com./haruhi/images/7/7e/Yuki_Nagato_2.jpg)

[@DeepSkyVideos]

they aren't pixellated - they're a pair of telescopes called MAGIC and we'll be doing a video on them too!!!

[@BlindSoothsayer]

Herschel also wrote a few symphonies.

[@JustOdie]

7:29 So Dobsonians are basically tiny giant telescopes.

[@pbezunartea]

As usual, wow! very interesting!

[@ohmyfignuts]

the chirping is the compressors cooling the instruments.

[@themaskedcrusader]

1:16 - Classified buildings?

[@charlesinsandiego2537]

1:18 to 2:18 what is that horrid squeak? Don't they oil that thing?

[@zapfanzapfan]

That is the sound of a cryocooler. There is probably some instrument on the telescope that needs to be at 4 Kelvin or something like that.

[@charlesinsandiego2537]

Ah, thanks. Still horrid, though.

[@DivingDeveloper]

Clearly the future is in the NGC catalogue :)

[@piranha031091]

It is more simple and efficient to place them on earth orbit, as we do with all space telescopes. (Hubble, Chandra, Spitzer, Planck, Herschel, etc...)

[@boboften9952]

" You Call That A Telescope " " This Is A Telescope " What Crocodile Dundee Would Have Said .

[@WeaselWJ]

Professor Merrifield's legs. Haha!

[@Gastel]

An interesting idea, but it sounds like Hubble type telescopes would be easier to build and deploy.

[@mixedartmaster]

amazing size

[@Uhor]

brady still says "mirror" the sexiest way!

[@syphonized6151]

i wish i could just be in chili on the mountaintops for one night to see the sky. where i live i can hardly see any stars :/

[@KarlFarbman]

Why in the world does this episode have so few views and likes?!

[@boboften9952]

Thank You Brady . Thank You Javier Mendez .

[@Pianoguy32]

would it be commercially viable to produce telescopes? hmm

[@MarcusZabo]

To bad he did not have a DSLR for that shot of Mars!

[@paulfrancis8836]

why didn't they build the telescope on huge huge half sphere, then it could cover the entire sky.

[@basalisk335]

orbit works fine too and is more practical for now.

[@Destro7000]

inside the WHaT?

[@MuadDib1402]

MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov Telescopes) Wiki.

[@S13v7n]

And the upcoming James Webb Telescope to replace Hubble ;)

[@mokopa]

Here's me rooting for the South African Large Telescope (S.A.L.T.)! Root root!

[@TheTrueRandomness]

That's why the built the Hubble Space Telescope ;-)

[@SeraphimKnight]

Did you film these videos not knowing in which order you'd post them? It's really necessary to repeat how a telescope functions every time you show us one...
