Target entity: Ritchey–Chrétien reflector
Context triple: [Baade Telescope, telescopeType, Ritchey–Chrétien reflector]
  • A. Baade Telescope
    The Baade Telescope is one of the twin 6.5-meter Magellan optical telescopes used for cutting-edge astronomical research in Chile.
  • B. Las Campanas Observatory
    Las Campanas Observatory is a major astronomical observatory in Chile renowned for its high-quality observing conditions and its role in cutting-edge optical and infrared astronomy.
