The VISAC optical system is composed of a concave primary mirror, a convex secondary mirror and a three-element field corrector at the base of the focuser. Vixen VC200L telescope features rack-and-pinion focusing mount that accepts optional 2” eyepieces and accessories. Open tube design eliminates the dew problem that is common with conventional Schmidt or Maksutov-Cassegrain systems and its size makes it very easy to handle. 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. Especially noteworthy in the Vixen VC200L is its sharpness and flatness at the edge, which far exceeds that of Schmidt-Cassegrain systems of the same aperture. It provides a pinpoint star image less than 15-microns, even at the edge of its 42mm image circle. If you are looking for a photographic catadioptric, the Vixen VC200L is an excellent choice. The Vixen VC200L telescope features the VISAC optical system. The VISAC optical system is composed of a concave primary mirror, a convex secondary mirror and a three-element field corrector at the base of the focuser. The primary mirror is a unique innovation: a precise sixth-order shape produced by Vixen's High-Precision Poly-Order Aspherical Mirror Molding Technique. The Vixen VC200L is well suited for observation and astrophotography of the moon, planets, star clusters, nebulae, and comets. The rack-and-pinion focusing mount accepts optional 2” eyepieces and accessories, and an f/6.4 reducer for photographic use is also available. The open tube design of the Vixen VC200L eliminates the dew problem that is common with conventional Schmidt- or Maksutov-Cassegrain systems and its size makes it very easy to handle. The new white VC200L telescope has a lighter-weight optical tube with improved anti reflection coatings, a metal carrying handle and now comes standard with a 7x50mm finderscope. Works great with Vixen Sphinx or GPD2 equatorial mount. Vixen VC200L 8" f/9 Modified Cassegrain OTA Specifications
