How did galileo perfect the telescope?
I’ve actually seen Galileo’s telescopes in the science museum in Florence, and they are far from “perfected.” Galileo’s importance was not in the telescope itself, which he copied from a Dutch design, but in the fact that he used it for astronomy, making him the first major pioneer in observational astronomy.
Which type of telescope are you talking about, Galileo did not invent or perfect the telescope, that came later by people like Sir Isac Newton of England who invented the reflecting telescope (Newtonian) a variant of which is the type of telescope used by most astronomers since 18th Century. Galileo only used the (refracting) telescope for observing the night sky, while most people used it for military purposes. The Richy Chretien telescope is probably the most perfect type of telescope for observations, but it is far, far removed from that Galileo used, which was put together with spectacle lenses.
He is right, but to answer your question, Galileo IMPROVED the telescope.Galileo made the instrument famous. He constructed his first three-powered spyglass in June or July 1609, presented an eight-powered instrument to the Venetian Senate in August, and turned a twenty-powered instrument to the heavens in October or November. With this instrument (Figure 5) he observed the Moon, discovered four satellites of Jupiter, and resolved nebular patches into stars.
