Product description

TS-Optics 6" f/12 Classical Cassegrain Telescope

Cassegrain telescopes combine the benefits of a Newtonian telescope being a pure reflective system with a short-built design. Cassegrain telescopes are mainly used for photography of the moon and the planets and for observation of astronomical objects. 

Main features

  • Large corrected and illuminated image field due to parabolic primary and hyperbolic secondary mirror with less field curvature than with SC telescopes.
  • Pure reflection system without Schmidt plate, as a result even Infrared photography becomes possible at full sharpness.
  • Significantly quicker temperature adaption than a SC, due to open design.
  • Brighter image due to 96% dielectric coating on primary and secondary mirror.
  • No shifting, because the primary mirror is fixated
  • High-quality 2" Crayford focuser with micro-gear reduction and compression rings for 2" and 1.25" accessories
  • 38% obstruction caused by secondary mirror, comparable to SC telescopes.
  • Better sharpness on the optical axis due to precise mirror surfaces and the lack of a Schmidt plate
  • Less problems from dew: with Schmidt-Cassegrains you get condensation on the front plate, not with a Cassegrain
  • Interior baffles for even higher contrast
  • Generous backfocus allowing the use of 2" accessories.
