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 7x50 finder, 232mm tube rings,
dovetail tube plate and new focus design with more distance for
photographic equipment, as well as being compatible with the new Sphinx
mount. Install Vixen's new Dual Speed Focuser for fine focus observing.
The 7x50 achromatic finder has a field of view of 6.8" and a Kellner type eyepiece.
