Question

What are the functions of a Newtonian Telescope ?? Who ever answers this with diagram will be marked a branliest

Answer 1

They are free of chromatic aberration found in refracting telescopes. Newtonian telescopes are usually less expensive for any given objective diameter (or aperture) than comparable quality telescopes of other types.



Newtonian telescope design

The Newtonian telescope, also called the Newtonian reflector or just the Newtonian, is a type of reflecting telescope invented by the English 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.[1] The Newtonian telescope's simple design makes it very popular with amateur telescope makers.
