Newtonian telescope design A Newtonian telescope is composed of a primary mirror or objective, usually parabolic in shape, and a smaller flat secondary mirror. The primary mirror makes it possible to collect light from the pointed region of the sky, while the secondary mirror redirects the light out of the optical axis at a right angle so it can be viewed with an eyepiece.. 8.1. The Newton reflector The most popular telescope design among amateurs - Newtonian reflector - consists from a single concave primary mirror and a reflecting flat. It is a single optical surface of the primary mirror that creates the image, while the flat merely directs light out to the side, to an accessible observing location.
The Newtonian Reflecting Telescope There are two basic types of Telescope, the Refractor, which uses a Lens as its' primary light gathering objective (binoculars are an example of this type) and the Reflector, which uses a Mirror to collect the light. Within each group there are many sub-divisions. However, the most popular type that many amateur astronomers begin with is known as a.. INTRODUCTION A Newtonian reflecting telescope can be designed to perform more efficiently than any other type of optical system, if one is careful to follow the laws of nature. One must have optics made from precision Pyrex or a similar material and figured to a high quality. The mounting hardware must be well planned out and properly constructed using highest quality materials. The Newtonian.
