Web1. Newtonian. 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. WebA Ritchey–Chrétien telescope ( RCT or simply RC) is a specialized variant of the Cassegrain telescope that has a hyperbolic primary mirror and a hyperbolic secondary mirror designed to eliminate off-axis optical errors ( coma ).
