VIXEN R200SS 200mm (8") f/4 Newtonian OTA



  • Model: 5869
  • Manufactured by: Vixen


VIXEN R200SS 200mm (8") f/4 Newtonian OTA

The remarkably fast 200mm (8") f/4 parabolic primary mirror of the Vixen R200SS Newtonian reflector gives extremely sharp images with no chromatic aberration. The use of state-of-the-art coating technology yields the ideal surface for its f/4 primary mirror. The visual observer will enjoy wide views of deep sky objects. Actual groups of nebula or clusters can be viewed at the same time with this instrument.

The telescope's large aperture and compact body make it ideally suited for astrophotography of nebulae, star clusters and comets. The use of the optional coma corrector allows for a sharp coma-free image from edge to edge, and the rack and pinion focuser, with an adapter, accepts 2 eyepieces.

The R200SS comes standard with the  232mm tube rings, dovetail tube plate and new focus design with more distance f or photographic equipment, as well as being compatible with the new Sphinx mount. Install Vixen's new Dual Speed Focuser for fine focus observing.
