The Vixen VC 200L Reflector Telescope 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 telescope's 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, the VC200L telescope 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."
- Primary mirror held in retaining ring rather than hooks, improving contrast
- High quality resolution even at edge of field
- Works well with prime focus and eyepiece projection
- Flip mirror diagonal included - makes visual observation possible while set up for astroimaging.
