Multiple Mirror Telescope

Target entity: Multiple Mirror Telescope
Context triple: [MMT Observatory, namedAfter, Multiple Mirror Telescope]

• A. 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.
• 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. Magellan Telescopes
  Magellan Telescopes are a pair of 6.5-meter optical-infrared telescopes at Las Campanas Observatory in Chile, used for cutting-edge astronomical research by an international collaboration.
• D. 20 Meter Telescope
  The 20 Meter Telescope is a mid-sized radio telescope at the Green Bank Observatory used for astronomical research and education in radio astronomy.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Multiple Mirror Telescope
Target entity description: The Multiple Mirror Telescope is a pioneering astronomical observatory instrument in Arizona that originally used six smaller mirrors to function as a single large telescope, significantly advancing optical and infrared astronomy.
