newtonian reflector diagram. The larger, curved mirror directs incoming light to a focus.
The smaller, angled. The Newtonian reflectorThe Newtonian reflector is the classic mirror telescope design. The principle is straightforward yet ingenious.
Isaac Newton first built this . Isaac Newton developed the reflector about , in response to the chromatic aberration (rainbow halo) problem that plagued refractors during his time.The Newtonian reflector was a highly successful design, and remains one of the most popular telescope designs in use today.

Focusers are one of the most commonly replaced or upgraded items to be found on a telescope. In some instances this is done to provide finer granularity of focus adjustment.
In other cases the focuser is replaced to allow for motorized or hands free focus adjustment.5/5(1). The light enters the telescope from the left and is focused by reflecting off the large Concave Mirror.
Since the focus is inside the telescope, it is difficult to see the result or put an instrument there. Normally telescopes use another mirror to move the focus somewhere else (see the ray diagrams for Newtonian and Cassegrain telescopes). 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 (–), using a concave primary mirror and a flat diagonal secondary mirror.
