WebNov 23, 2024 · I have a 130pds newtonian reflector with a coma corrector, and am happy with it. It has a short focal length (650mm) and so is wide field. It is a lot cheaper than an apochromatic. There is an extra challenge with balancing a newtonian, as I have to rotate the telescope within the mounting rings. (I find it hard to explain why. WebThe Maksutov, like a Schmidt-Cassegrain is between Newtonian reflectors and high end refractors in the aperture/cost ratio.

Lovingly referred to as a “Newt,” this is the simplest type of reflector: a parabolic mirror that reflects the light back to a secondary mirror at a 45º angle, which directs it to an eyepiece or camera. These are excellent for beginners, have short focal ratios, and can have large apertures.
