Vixen is a Japanese company that makes telescopes, binoculars, spotting scopes and accessories for their products.[1]
Among many other more mainstream products they have created two unusual varieties of catadioptric telescopes with an open tube design instead of the full-aperture corrector plate of the Schmidt–Cassegrain and most Maksutov–Cassegrain designs.
This design is based on the Maksutov–Cassegrain. It provides correction of aberrations via a two-element meniscus-shaped corrector lens in front of the secondary mirror. This design was originally envisaged by G. I. Popov with a practical implementation by Yu. A. Klevtsov. It is produced with apertures of 8, 10.25 and 13 inches. The 8-inch model employs a refractor style rack and pinion focuser, while in the larger designs the primary mirror is moved as in most other small to medium-sized Cassegrain designs.
