The sources of Galileo is he wasn't the inventor of the telescope,but he was the first to use the telescope. Also he improved the telescope making an object look about 20 times bigger.Also,he made it magnify 3 times as much as before made this improvement in 1608-1609.
many craters, mountains, and what Galileo referred to as 'seas'.
The cost of a reflecting telescope can vary greatly depending on the size, brand, and quality of the telescope. Entry-level reflecting telescopes can start at around $200, while more advanced models can cost several thousand dollars or more.
The shape of the lens means light near the top of the lens is bent down and light near the bottom of the lens is bent up. Somewhere inside the tube the light beams cross, but before they can spread out again the eyepiece lens bends the light beams again and sends them to the eye.
Galileo's improved telescope allowed him to observe detailed features of celestial bodies, such as the phases of Venus and the moons of Jupiter. These observations provided evidence that not all celestial bodies orbit Earth, supporting the heliocentric theory proposed by Copernicus.

Galileo Galilei discovered phases in Venus -- pretty much proof of a heliocentric solar system -- in 1610 September.

The invention of the telescope is credited to Hans Lippershey. Crude telescopes and spyglasses may have been created much earlier by Dutch opticians, but Lippershey is believed to be the first to apply for a patent for his design. His telescope was made up of one convex lens and one concave lens.Galileo Galilei perfected it by using two convex lenses. He constructed his first telescope in 1609. This telescope is called the Galilean telescope or the refracting telescope.Isaac Newton invented a telescope which used two mirrors. He constructed his first telescope in 1669. His version of the telescope was called the Newtonian telescope or the reflecting telescope.
The annual operating cost for the Hubble Space Telescope is approximately $100 million.
it cost 53 p.

The big one for the Earth, of course, which everybody sees. But Galileo was the first known person to see the four "galilean" moons of Jupiter; Europa, Callisto, Ganymede and Io. There are another 60 or so moons of Jupiter, but they are all much smaller; far too small to be seen in Galileo's early telescope!
