Telescopes are used inside
Light is found by reflecting telescopes and refracting telescopes are used to dected sound
Optical telescopes.
The first telescope didn't look exactly like the ones that we see today, but it was improved though by the famous astronomer Galileo. The first one is said to have been made about 500 years ago.
Telescopes were first used in 1952 by Oxford scientist Ron L. Hubbard--his predecessor, Mallory Hieney, first saw the planets with his device. Its called a fefracting telescope.
Telescopes are instruments used by astronomers. The first person to do this was Galileo.
Around 1608.

Collimation is used for telescopes to make sure the telescopes are perfectly aligned. The reflector will not produce the best image if the aligned is not just right.
Optical telescopes.
The largest telescopes that use visible light are reflector telescopes.
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
