The VC200L is a 200mm (8 inch) f9.0 well-corrected, specialised telescope which has been engineered to meet the demands of the astro imager.

Vixen's unique catadioptric design features a high precision sixth order aspherical primary mirror, a convex secondary mirror and triplet corrector lens placed between the secondary mirror and focusser. In combination, these optical elements form Vixen's VISAC (Vixen Sixth-Order Aspherical Cassegrain) design.

The primary mirror is held by a retaining ring, instead of hooks to decrease flare and enhance contrast.

The VISAC design provides high-definition star images to the edge of a wide viewing field and offers excellent performance for astrophotography. Even at the edge of 35mm film format CCD chips, stars are sharp and typically better than the resolution of high quality CCD imagers. This means that the telescope does not limit image quality.

Typically exposure times of around 10 minutes are required when using this scope for deep sky imaging. An optional f6.4 focal reducer allows for much shorter exposure times.

The tube is supplied with a dovetail mounting rail. The rail is covered with a stainless steel plate on one side to prevent marking from mounting set screw or compression plates.

The integrated carry handle makes this lightweight tube easy to transport to remote imaging sites.

Astrophotographers generally use two different focal lengths: Short focal lengths for overview photos and extensive deep-sky objects, and long focal lengths for objects which are further away. Our aspherical mirror optics offer the perfect solution for these scenarios. The VISAC primary mirror (Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and provides a fully flat and true-colour image over the entire image frame. Thanks to the three-element field corrector in front of the convex secondary mirror, there is no spherical aberration, coma or field curvature. Although the device is designed for astrophotography, it is also suitable for visual observations.

Aluminium Vacuum Evaporation System
Vixen has created a unique aluminium vacuum evaporation system to produce extremely precise mirror surfaces. More accurate than the error-prone process of grinding material to form a mirror surface, Vixen's revolutionary system works by controlled layering of aluminium film. The primary mirrors in the unique sixth-order aspheric Cassegrain fitted to the VC200L as well as the 200mm Newtonian R200SS are produced using this aluminium vacuum evaporation system.
