Kit composed by the Vixen VC200L Aspherical Cassegrain OTA and the Reducer HD 0.79x focal reducer. High-performance system suitable for modern large-size CCD and CMOS sensors with tiny pixels. Contact us for info about connecting your DSLR or your CCD / CMOS cameras.
The Vixen VC200L is 20 cm F/9 modified Cassegrain OTA. The Vixen VC200L's catadioptric VISAC (Vixen Sixth-Order Aspheric Cassegrain) optical system is one of the most sophisticated optical designs available on the market today: free of coma, curvature of field, spherical and chromatic aberration.
SkyWatcher Quattro 10-S Newton reflector optical tube features a large 254 mm primary mirror (10"), 1000 mm focal lenght (F/4), 8x50 finder view, 2" Crayford dual-speed focuser, mounting rings and dovetail bar.
Kit composed by the Vixen newtonian reflector R200SS, the Vixen Corrector PH that takes down the focal ratio to F/3.8 (focal length 760 mm) and the Vixen Extender PH 1.4x that takes up focal ratio to F/5.6 (focal length 1120 mm). Correctors are both optimized for full-frame sensor delivering a corrected image circle up to 44 mm. Vixen AS Coating for...
