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.
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.
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!
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.
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.
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!
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.
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
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...

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

Thanks for posting 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!
Informative as always Brady. Also, Dem Legs!
Kinda depressing these videos have mostly been forgotten. They're still top notch 8 years later!
I’m here binge watching in 2022! Loving them. I hope they’re not forgotten.
thank you - we'll have more from the WHT soon
Love the videos. Will u be doing any follow ups on the 3 things you mention at the end.
More about the WHT, including its "adaptive optics" is coming soon!

very interesting video, thank you brady! waiting for more!!
I get to go here in November! Super excitement!
we've done one video on that (I assume you saw it!?) and another one is likely tomorrow!
cheers... there's more astronomy on my sixtysymbols channel too (with some of the same people in deepskyvideos)!
Could you make a video where one of the professors describe how such telescopes function in detail ?
Humbly fascinating.
if they do, that'll be a great place to visit and make a DeepSkyVideo!!!!

I would assume they could spin the camera or "instrument" in the opposite direction to compensate that.
i love you vids brady

can anyone apply for use of the telescope (if u know what ur doing) or do u have to be with a uni?
rightly so... very cool!
any more news on that supernova in M95 ?
01:18 what are the strange pixellated objects in the foreground?
What's that noise that sounds like an MRI inside the dome?
You sound so exited in the first few seconds of the video, Brady! Hard to blame you!
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.
Dear DeepSkyVideos
Could you make videos about all the 88 constellations, and their deep sky objects, after you finish the messier objects?
there's more coming!
What are the two circles that appear to be pixels at 1:15??
As usual, wow! very interesting!
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)

What Crocodile Dundee Would Have Said .

Professor Merrifield's legs. Haha!
they aren't pixellated - they're a pair of telescopes called MAGIC and we'll be doing a video on them too!!!
Clearly the future is in the NGC catalogue :)
1:16 - Classified buildings?
7:29 So Dobsonians are basically tiny giant telescopes.
the chirping is the compressors cooling the instruments.
Herschel also wrote a few symphonies.
1:18 to 2:18 what is that horrid squeak? Don't they oil that thing?
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.
Ah, thanks. Still horrid, though.
amazing size
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...)
brady still says "mirror" the sexiest way!
An interesting idea, but it sounds like Hubble type telescopes would be easier to build and deploy.
Thank You Brady .
Thank You Javier Mendez .
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 :/
would it be commercially viable to produce telescopes? hmm
Why in the world does this episode have so few views and likes?!
To bad he did not have a DSLR for that shot of Mars!
orbit works fine too and is more practical for now.
MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov Telescopes)
Wiki.
Here's me rooting for the South African Large Telescope (S.A.L.T.)! Root root!
why didn't they build the telescope on huge huge half sphere, then it could cover the entire sky.
inside the WHaT?
And the upcoming James Webb Telescope to replace Hubble ;)
That's why the built the Hubble Space Telescope ;-)
woooo
