A Ritchey–Chrétien telescope (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 RC has a wider field of view free of optical errors compared to a more traditional reflecting telescope configuration.
