Phrase: Ritchey–Chrétien telescope | Statement: [Southern Astrophysical Research Telescope, telescopeType, Ritchey–Chrétien telescope]

Target entity: Ritchey–Chrétien telescope
Context triple: [Southern Astrophysical Research 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. Cassegrain telescope
  A Cassegrain telescope is a reflecting telescope design that uses a combination of a primary concave mirror and a secondary convex mirror to fold the optical path and produce a compact instrument with a long effective focal length.
• C. 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.
• D. Maksutov telescope
  A Maksutov telescope is a compact catadioptric reflecting telescope that uses a meniscus corrector lens to deliver sharp, well-corrected images with relatively simple alignment and maintenance.
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
