Newtonian Telescope

The Newtonian telescope (Newton telescope) is a type of reflecting telescope invented by the British scientist Sir Isaac Newton (1642–1727), using a concave primary mirror and a flat diagonal secondary mirror. Newton’s first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newton telescope’s simple design makes them very popular with amateur telescope makers.

What is the first telescope in the world? – Galileo Galilei’s telescope
What is the best telescope? – Newton’s telescope
Why Newton’s telescope is better than Galileo’s? – Galileo’s telescope must make it longer so you can see it well, but about Newton’s you can see it well even you don’t make it longer!
