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.
