Time does not permit me to pursue astrophotography with this fine telescope.

The VC200L’s catadioptric optical system is one of the most sophisticated optical designs available on the market today and has recently received some manufacturing upgrades. The New VC200L has a lighter-weight optical tube with improved anti reflection coatings, a metal carrying handle and now comes standard with a 7x50 finderscope. If you are looking for a photographic catadioptric, this is an excellent choice.
With its unique VISAC (Vixen Sixth-Order Aspheric Cassegrain) primary mirror, the telescope gives a sharp image that is free of chromatic aberration and is flat and sharp to the edge of 35mm film.
The VISAC optical system is composed of a concave primary mirror, a convex secondary mirror and a three element field corrector. Especially noteworthy is its sharpness and flatness at the edge, which far exceeds that of Schmidt-Cassegrain systems of the same aperture. It provides a pinpoint star image less than 15 microns, even at the edge of its 42mm image circle. The open tube design eliminates the dew problem that is common with conventional Schmidt-Cassegrain systems and its size makes it very easy to handle.
The VC200L is well suited for observation and astrophotography of the moon, planets, star clusters, nebulae, and comets. The rack-and-pinion focusing mount accepts optional 2” eyepieces and accessories, and an f/6.4 reducer for photographic use is also available.

“catadioptric fans should take a close look at this scope, since it does offer a few advantages compared to your standard issue Schmidt-Cassegrain. It costs more, but you get a lot. Stars are indeed pinpoints all the way out to the edge of the field.”
Ed Ting 12/03
