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.
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.
The astronomer studied distant galaxies using a powerful telescope.
Some disadvantages of using solar energy include the high initial cost of installing solar panels, the intermittent nature of sunlight depending on weather conditions, and the need for large amounts of space for solar panel arrays in order to generate significant amounts of electricity.
The new planets are named after the Kepler Space Telescope, which was a NASA mission that searched for exoplanets using the transit method. The telescope discovered thousands of exoplanets during its mission.
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.
Galileo discovered stars by using the telescope?
The Amazon River was not discovered by Galileo using a telescope.

What are disadvantages of using car?
Galileo is the first thought of using a telescope for looking at the stars.
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.
That's a "reflecting" telescope.
Usually, by using your eye sight, optical telescope, or radio telescope.
I don't know about the advantages, but lead will kill you if taking large amount.
large safety stocks increase holding cost
