Rc vs newtonian

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 ). The RCT has a wider field of view free of optical errors compared to a more traditional reflecting telescope ...
