The Newtonian telescope, also known as the Newtonian reflector, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton. It utilizes a concave primary mirror and a flat diagonal secondary mirror to form an image. This design allows the telescope to collect light from a specific region of the sky and redirect it out of the optical axis at a right angle for viewing with an eyepiece
. The primary mirror of the Newtonian telescope is usually parabolic in shape, and the secondary mirror redirects the light to the eyepiece
. The simple yet effective design of the Newtonian telescope has made it popular among amateur telescope makers and astronomers
The Newtonian telescope was developed as an alternative to refractive telescopes to combat chromatic aberrations that occurred in the latter
. Unlike refracting telescopes, the Newtonian telescope uses mirrors instead of lenses to capture light, eliminating issues with chromatic aberrations and distortion
. This design, first completed in 1668, remains popular due to its effectiveness and simplicity.
The Newtonian telescope's design includes a primary concave mirror and a secondary flat diagonal mirror, and it is known for its light-gathering ability
. However, like other reflecting telescopes using parabolic mirrors, the Newtonian telescope is subject to coma, an off-axis aberration that affects the imagery
