That's what I was thinking. 26 tons sounded waaay too much for a lense with a diameter of 1m. I mean, unless the depth of the lense was at a magnitude of meters.

Lippershey's telescope actually had a negative lens as an ocular, just like Huygens and Galileo by the way. But for purposes of clarity I can understand this choice of explanation. Very well done!
We moved away from refractors not because of light absorption, but because of Chromatic aberration - even with achromats, as aperture increases in size, focal ratio needs to grow much faster in order to offset chromatic aberration. The two lenses are unable to bring all the colors into focus. It wasn't until the creation of apochromats with their ED/Flourite elements that refractors - but those don't work on large scales because it is prohibitively expensive. There is also the issue that very large lenses are very thick, very hard to make. Once you get past a certain point, the glass will just bend and flex due to its own mass, which of course ruins the image. Reflectors have the same issue, but they are at least supported on one end. We've also solved it using segmented mirrors and fancy engineering tricks. The creation of adaptive optics allow us to get very clear, distortion free views of space at a fraction of the cost of a space telescope.
I impulsively bought a 500 telescope, when I opened it, I was very disappointed to find out it wasn’t a camera, 😂😂😂 then I came here to find out how a telescope actually works. I’m still enjoying my telescope as much as I thought I was going to. It was just a humbling moment realizing telescopes are not actual cameras xD
Not an optical telescope. But yes, it's one of the biggest all categories telescope with the FAST (500 meters diameter). But if we count the interferometers, well, there's no limit except the size of the Earth!
This proves the earth is flat, Because we have a limit on how much we can see,SO when you see a boat disappear from the edge,And zoom in on it with a telescope YOU WILL SEE IT AGAIN, IF IT WAS A BALL YOU WOULDN'T!
Nice video, but to be honest, I am not really satisfied with some of the explanations. Firstly the magnification of the telescope can not be understood by what you've said. The image does not look bigger, because the the object seems to be at front of your eyes. If this would be the case then stars shoul also be bigger, but they are also point-like trough telescope. The real answer comes if you sent other parellel lights trough the telescope. In this case you should observe that the angle, the lights comes into the objective is sometimes greater at the ocular. This magnification of the angles is the real deal. Furthermore, Newton-type telescopes are not primary good for the lack of reflected light on the objective. Mirrors ara much easier to produce, much lighter, and they does't have the effect of cromatic distortion.
WHY is everything that is scientific narrated by some guy with a British accent? And I still havent found out if a telescope ZOOMS like a camera lens or are they fixed?
I haven't seen yet a good explanation of why objects are augmented through a telescope. In fact, the focal length of objective versus focal length of eyepiece appears to reduce the size of the object (by same proportion)!
How about this the 90 reflector telescope. For the future terrestrial planet finder which was supposed to be launched back in 2009 however the plans to launch the telescope has been postponed twice
Wait clean ,rub together another telescope atmosphere or send one up to space Your the twinkle in eye and guy put refractive telescope in garden, the gas in atmosphere makes the twinkle in sky lol
So if the telescope is deployed into space to prevent atmosphere distortion, and these things are taking images millions of light years away , how doesn't the signal get disrupted by any planets /objects in that line of sight ?

The Fantastically Accurate Reflector Telescope... It's FART, right?
Yup! I work in an observatory so I plan to write down the acronym on the meeting room whiteboard to see how people react :D

"looks into the sun with a 30 meter telescope''
😂.. with a 30m reflector telescope"
Greg: "Get rid of the atmosphere"
Me: "OK!" **pauses video and gets rid of earth's atmosphere**
Hyper I bet u forgot about this bad bad joke
Ivan my friend
This video helped me in my school project
Wait a second.
A glass lense that's 1m in diameter that weighs 26 tons?
....Or did you mean that the whole telescope is 26 tons?
I estimate about 1000 kg or less, using a density of 2.51 g/cm3.
That's what I was thinking. 26 tons sounded waaay too much for a lense with a diameter of 1m.
I mean, unless the depth of the lense was at a magnitude of meters.
This video was really helpful!! Thank you so much for explaining it clearly :)

@@harrydibden3365the comment was 6 yrs ago so the channel would have been much smaller
Wow, you didn't even mention the upcoming JWST?
Ha ha! Fantastically accurate reflector telescope
wow last time i was this early this channel didn't exist
There are some errors in the ray diagram of the refracting telescope, kindly do go through it.
Love it how this channel explains everything in such depth and understandable for everyone! :)
Cheers Bojan!
His accent omg
simp!!! who do you simp for now? todoroki? Gojo? Fushiguro? (this is a joke, don't come for me)
Anyone else here from Easy Peasy?
Yesss!!
Really fantastic explanation. Information kept simple and presented as good as it gets.
good video, but why dont we see a dark spot in reflection telescopes where the little inner mirror is?
Came here from school 😔
Fantastically Accurate Reflector Telescope =3 😂
Can we use the gravitational lensing of a black hole for the same purpose.
good video
The Outlook notifaction sound at 4:11 made me check my email.

What a simple explanation! In my text its explained like a FUKn rocket science.

Fantastically Accurate Reflector Telescope (FART) 😂😂😂
Surprised that you didn’t mention anything about James webb telescope
what about the Arecibo Radio Telescope 305 meters across(1000 ft) surely that qualifies as large
Not an optical telescope. But yes, it's one of the biggest all categories telescope with the FAST (500 meters diameter). But if we count the interferometers, well, there's no limit except the size of the Earth!
fantastically useful crazy keplar telescope
I bet flat earthers loved your comment about seeing a firefly in Tokyo from NYC 😁
Yes there is enough light bouncing off those objects - it just scatters so much over distance, very little - if any reaches our eyes.
that is a good point!
Perhaps a video on radio telescopes, including the plans and status of the Square Kilometre Array (SKA) project?
the acronym is fart. humour level 100. well done.
Global Warming will help us get rid of earths atmosphere. Then we can see the stars.
Can light can come to telescope from 1 light year distance to see that object
Omg !
Is BBC VENUS LAB
BBC MERCURY LAB
BBC JUPITER LAB also exist!
what
im here cause saw about james webb telescope so still trying to get how that telescope will be working haha
that face at 0:00 lmao
You forgot to mention the Radio Telescopes !!
Webb’s Telescope first images brought us here
And now we have the James Webb Space Telescope 5 years later
Good
Wow
Great video I’m expert now !🤓
This proves the earth is flat, Because we have a limit on how much we can see,SO when you see a boat disappear from the edge,And zoom in on it with a telescope YOU WILL SEE IT AGAIN, IF IT WAS A BALL YOU WOULDN'T!

where is james webb telescope?
are you serious right neow bro

Just a thought but you guys should give images of the examples you're talking about
Very helpful video!
i need to watch this for homeschooling work XD
Is there a blind spot in the centre of the mirror telescope? Or is the mirror that reflects into the eyepiece one-way?
came into this video not knowing how telescopes work. leaving this video knowing how telescops work. thank you bbc :)
WHY is everything that is scientific narrated by some guy with a British accent? And I still havent found out if a telescope ZOOMS like a camera lens or are they fixed?
Why every dmb comment comes from Indian or Muslim?
@@tgstudio85 Are you implying I'm Indian or Muslim?
I always thought that stars twinkled because of their wobble? Maybe a combination of both atmospheric distortion and their wobble??

Why not point your telescope straight up so that it has less atmosphere to view the stars through?
I thought Five hundred meter Aperture Spherical Telescope (FAST) was the largest telescope?
Wibbly wobbly
Thank - you .

Question: Why Doesn't the secondary mirror in reflector telescopes create a black spot in the middle of the image?
What is your view on James Webb Space Telescope. Can you make a video on it ?
How about this the 90 reflector telescope. For the future terrestrial planet finder which was supposed to be launched back in 2009 however the plans to launch the telescope has been postponed twice

So if the telescope is deployed into space to prevent atmosphere distortion, and these things are taking images millions of light years away , how doesn't the signal get disrupted by any planets /objects in that line of sight ?
I am pretty sure telescopes were built years earlier before 1608.
Are telescope with concave mirror better than those with convex lins?
