Target entity: Ritchey–Chrétien telescope
Context triple: [Canada–France–Hawaii Telescope, telescopeType, Ritchey–Chrétien telescope]
  • A. Ritchey–Chrétien reflector chosen
    A Ritchey–Chrétien reflector is a specialized type of reflecting telescope that uses hyperbolic primary and secondary mirrors to produce a wide, coma-free field of view ideal for professional astronomical imaging.
  • B. Schmidt telescope
    A Schmidt telescope is a wide-field reflecting telescope design that uses a spherical primary mirror and a correcting lens to capture sharp images over a large area of the sky.
  • C. Schmidt–Cassegrain telescope design
    The Schmidt–Cassegrain telescope design is a compact catadioptric optical system that combines a spherical primary mirror with a Schmidt corrector plate to provide long focal lengths in a short, portable tube widely used in amateur and professional astronomy.
  • D. Maksutov–Cassegrain telescope design
    The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
  • E. Dall–Kirkham telescope design
    The Dall–Kirkham telescope design is a type of reflecting telescope that uses an elliptical primary mirror and a spherical secondary mirror to provide good on-axis image quality with relatively simple, easy-to-manufacture optics.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
