The Vixen VC 200L Reflector Telescope is an 8" f/9.0 highly corrected, highly specialized Vixen 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 Vixen Telescope mirror is held by a retaining ring, instead of hooks, to decrease flare and enhance contrast.

The VISAC System incorporated into the Vixen VC 200L Reflector Telescope 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 Vixen Telescope does not limit the image quality.

With its elaborate aspherical optical design, the Vixen VC 200L Reflector Telescope achieves excellent image correction throughout the large illuminated field. (42mm diameter fully illuminated) Astronomy Technology Review states: "The VC200L Vixen Telescope 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." With the f/6.4 reducer you get much shorter exposure times. Vixen'''s Dual Speed Focuser and compression ring are included.

Star Book One Functions: Celestial, Solar, Lunar, and King''s Rate Tracking, Slewing Speeds Variable from 0.1x to 999x sidereal , Backlash Compensation, PEC, Autoguider port, Screen Brightness Adjustable, Direction Keys, Red LED Light

Easy Secure Setup: The Vixen Sphinx SX2 Mount sets up in minutes. One bolt secures it to the tripod. Beginners and seasoned hobbyists will benefit from the portability of the Vixen Telescope Mount, the easy to use controller, the ability to download future upgrades directly to the controller and the versatility of placing a variety of Vixen Telescopes on this equatorial Vixen Telescope Mount with Vixen'''s universal dove tail plate.

Unique Motor Layout: The internal placement of the the RA and DEC motors in the Vixen Sphinx SX2 Mount allow the motors to act as a built in counterweight. Small Vixen Telescopes require no additional counterweights.

Retractable Counterweight Shaft: Constructed of corrosion resistant stainless steel, it retracts into the Vixen Sphinx SX2 Mount body for easy storage.

Don''t forget... We also carry many fine Vixen Accessories including Vixen Eyepieces, and Vixen Reducers and Adapters. There''s a complete line of Vixen Telescope Mounts and Vixen Camera Mounts, too!
