The Vixen VC 200L Optical Tube Assembly

INSTANT $200 REBATE June 1-July 31, 2010

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 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 an excellent image correction throughout the large illuminated field. (42mm diameter fully illuminated) With the f/6.4 reducer you get much shorter exposure times. Rack and Pinion Focuser=No Image Shift.
