The VC 200L is an 8" f/9.0 highly corrected, highly specialized telescope for astro imaging. Vixen's unique catadioptric design features a high precision sixth order aspherical primary mirror, a convex secondary mirror and triplet corrector lens. VISAC is an abbreviation for Vixen's Six-Order Aspherical Cassegrain. The primary mirror is held by a retaining ring, instead of hooks, to decrease flare and enhance contrast.

The VISAC System provides high-definition star images to the edge of a wide viewing field and offers exceptionally outstanding performance in astrophotography. Even at the edge of the 35mm film format (larger CCD chips) stars are sharp ( smaller than 15 micrometers) This is smaller than the resolution of fine quality CCD cameras, which means that the telescope does not limit the image quality. With its elaborate aspherical optical design it achieves excellent image correction throughout the large illuminated field. (42mm diameter fully illuminated) Astronomy Technology Review states: "The VC200L focuser is one of the smoothest I've ever tested...overall the visual image quality of the VC200L was quite impressive...and is a step up from the typical Schmidt-Cassegrain".

The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With it’s solid steel R. A. and Declination axes and brass worm gears this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography the worm, gears are especially machined to a very high precision that minimizes periodic error. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0° to 62° in altitude. Package Specifications:
