text: Like the refractor, there is a tube, but instead of lenses there are two mirrors (a primary at the bottom of the tube and a secondary flat diagonal mirror near the top), then a focuser and eyepiece, usualy on a dobsonian mount, but can be on a tripod, fork or other equatorial-type mount.
text: A 200mm Newtonian telescope has a secondary mirror with a diameter of 50mm.
text: The light enters the tube and reflects off a curved mirror (called the primary mirror) at the other end, before bouncing back up the tube to near the top where it reflects off a smaller mirror (called the secondary mirror), which bounces the light out of a hole in the side of the telescope where you attach your eyepiece.

text: The light enters at one end, It is then reflected by a concave-shaped primary mirror at the other end towards a smaller mirror known as the secondary mirror, This mirror reflects the light into an eyepiece which is usually mounted on the side of the telescope, and the eyepiece can be adjusted to alter the sharpness of focus.
text: Newtonian telescopes align the primary mirror using the laser collimator
text: The Newtonian reflector has a primary mirror at the end of the optical tube, and 45degree tilted secondary mirror at the front sending light to the eyepiece mounted right above the secondary mirror at the front of the optical tube.
text: It was revolutionary in that it used a secondary mirror that was diagonally mounted to reflect the image from the primary mirror at a precise ninety-degree angle.
