which is the biggest telescope in the world and what is its capacity and length ?

[sunofsky]

since I do not have a information about the largest telescope in the world, so which is the largest telescope in the world is available,and what are its results? how much its size? what is its length? and how big are its lenses? and whether this telescope is run through a computer program? is it fixed with an observatory ?

i guess it would have to be keck and keck 11, for how large it is i believe its 10 meters, and its located in hawaii, and the mirror is composed of 36 segments.
you prob can find alot more info at there web page,,

You Ass.

thanks dragon and ozzmosis, generally it is observed amongst the astronomy amatures that they don't have knowledge about telescope, its history, and lengths, and operation system, many starter or buyers of the telescope fails in viewing clear images through their telescope. Many tries with themselves, they don't go to observatories to see the planets and the sky. Most of them having a little telescope which result is so poor and they also not found satisfied. Yesterday one children ask me the same question that " if we see from a biggest telescope what will be the image's size? "

well the image is what the lense can capture , and at 10 meters omg thats a bucket of light caputer now to take pic they use plates and capture on cdd , i seen ccd as big as 135 mega
i think u can read about it here i think its the same one that i seen before

HOLY COW!
I could dream on for days of what it would be like just to look through any of those scopes in those Links!
Imagine what would happen if you bounced the light of the mid-day Sun, off of either of those, and placed a chicken at its Focal Point!
Fried Chicken Anyone?
At that size, do they employ something, to make up for atmospheric difraction?
They are both so huge! Im amazed that the glass, even though its segmented, can hold its shape under its own weight! I would not even contemplate about collimating something like that manually! How do they keep Monsters like that, at Thermal EQ?
Liquid Nitrogen? Alot of AC?
that is so impressive!

Actually they have many point actuators under the glass that place thousandths of an inch increments of change to get the focal point exact.

Very sensitive equipment indeed.

Also, they keep the observatory under exact atmosphere conditions to remove minute changes during observations.

HI Dragon!
That to me sounds like an egineering nightmare!
I would have a field day, just poking around to decipher for myself, as to how its done! way cool! the bigest scope I have ever looked thru, was a 24 inch Obsession, and that was showing a lot of hints of color on some objects I can Only dream!
