    Newtonian telescope - Wikipedia

    • The Newtonian telescope, also called the Newtonian reflector or just a Newtonian, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton, 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 Ne… 展开

    Variations

    There are several variations on the Newtonian design that add a lens to the system creating a catadioptric telescope. This is done to correct spherical aberration or reduce cost.

    History

    Newton's idea for a reflecting telescope was not new. Galileo Galilei and Giovanni Francesco Sagredo had discussed using a mirror as the image forming objective soon after the invention of the refracting telescope, and o… 展开
