The first problem is getting it up the mountain. For Mount Hamilton near San Jose, it took nearly a year to carve the road out of the forest and drag the Lick Observatory telescope components up the mountain - using horses.
The second problem can be light pollution; if your mountain is near a city, the glare of the city lights can make the sky so bright that it's difficult to see the stars.
Third was that in pre-computer days, the astronomer was limited to living at the top of a cold mountain, far away from civilization or his university, huddled up in coats and blankets and peering through the telescope eyepiece.
William Herschel discovered the planet Uranus, using a homemade telescope in the back garden of his house in Bath (England). It was also the first discovery of a planet made using a telescope. -------------------- a telescope
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
HST is a Cassegrain reflecting telescope using the Ritchey–Chrétien design, with an aperture of 7.9' (2.4m). It has observational ability in the Ultraviolet, Infrared, and Visible light spectrums.
The astronomer studied distant galaxies using a powerful telescope.
people first investigated the planets using the telescope!!!!!!!!!!!!!!
Galileo discovered stars by using the telescope?
The Amazon River was not discovered by Galileo using a telescope.
The reflecting telescope
Galileo is the first thought of using a telescope for looking at the stars.
a satellite image
What are disadvantages of using car?
the reflecting telescope was!!
The first large space telescope was the Hubble, and it's probably still the most famous one. But a LOT of the new and exciting work being done is using the Kepler Space Telescope, a device which was specially designed to search for planets around neighboring stars.
The planet Neptune was discovered by using a large telescope, in 1846. That was 167 years ago. Galileo, using a small telescope, discovered the first 4 moons of Jupiter in 1610. That was 403 years ago. (Since then, 63 more have been discovered.)
That's a "reflecting" telescope.
Usually, by using your eye sight, optical telescope, or radio telescope.
Yes, because it must be very large in order to attain the resolution of optical telescopes.
