Vixen VC200L Modified Cassegrain Telescope
This Vixen VC200L 8" f/9 Cassegrain Telescope is a highly corrected telescope specifically modeled for astrophotography. It features a unique catadioptric design with a highly accurate sixth order aspherical primary mirror, convex secondary mirror, and triplet corrector lens. In lieu of hooks, the primary mirror is held in place by a retaining ring in order to reduce flare and enhance contrast.
Vixen's VISAC system, an abbreviation for Vixen's Sixth-Order Aspherical Cassegrain, yields high definition stellar images to the edge of a wide field of view and allows for especially superior performance in astro-imaging. Stars will remain sharp (smaller than 15 micrometers) even at the fringe of larger 35mm film format CCD chips. As this is less than the resolution of many first-rate CCD cameras, the telescope will not affect the quality of the image. Thanks to its intricate aspherical optical design, this instrument attains excellent image correction completely through the large illuminated field (42mm diameter fully illuminated). Includes Vixen's Dual-Speed Focuser and compression ring.
