About this product
Model: vixen_r200ss
Part Number: 75869
The Japanese-made Vixen R200SS Newtonian reflector features a remarkably fast 200mm f4 parabolic primary mirror for extremely sharp images with zero chromatic aberration.
When used with Vixen's optional Wynne Coma Corrector (fits inside the R&P focuser draw tube) the R200SS also delivers coma-free image that are sharp edge-to-edge, even when using a full-frame DSLR!
The dual-speed R&P focuser provides plenty of back-focus distance for photographic equipment and, for visual use, accepts 1.25" and 2” eyepieces via an adapter.
Supplied with 232mm tube rings and dovetail plate.
Aluminium Vacuum Evaporation System
Vixen's unique aluminium vacuum evaporation system (controlled layering of aluminium film) produces an extremely precise mirror surface for high optical performance.
