GSO Ritchey-Chretien RC 355/2845 Carbon OTA

A dream telescope for astrophotography!

This Ritchey-Chretien optics with f / 8 gives very good pictures without the use of additional correctors and also permits the use of cameras with large sensors.

Your benefits:

  • Genuine RC-optics with hyperbolic primary and secondary mirror
  • Main mirror and secondary mirror made of quartz: no temperature-induced focus drift
  • The secondary mirror has a central marker for accurate collimation of the system
  • 99% coating with dielectric coating on primary and secondary mirror for a bright image
  • Large, flat and coma free field without corrector: ideal for astrophotography
  • Enough back focus for further optical accessories: 233mm from the tube back,127mm from the 2 "-Steckhülse the exodus

Thanks to the lightweight yet extremely rigid carbon spaceframe construction, the telescope is relatively easy. This way you can save on the mount. The "smaller" models of GSO RCs are therefore even more transportable. Further advantages of the open design, the rapid cooling time and the lower Tauprobleme against the Schmidt-Cassegrain optics.

Until recently belonged Ritchey-Chretien's most expensive telescopes. Thanks to GSO we can offer RC astrographs at affordable prices.
