Newton's reflector

A replica of a second reflecting telescope Newton presented to the Royal Society in 1672 (the first one he made in 1668 was loaned to an instrument maker but there is no further record of what happened to it).[1] It is described as the better of the instruments Newton built.[2]

The first reflecting telescope built by Sir Isaac Newton in 1668[3] is a landmark in the history of telescopes, being the first known successful reflecting telescope.[4][5] It was the prototype for a design that later came to be called the Newtonian telescope. There were some early prototypes and also modern replicas of this design.
