Vixen VMC330L, 15" Catadioptric Reflector Optical Tube with Finder Scope

Big 13" Aperture! Opens a New Window into Deep-Space...

With over 272% of the light gathering power of our 8" scopes, this unique system makes it possible to offer a Maksutov-Cassegrain-like design in a big but manageable package.

Consisting of Pyrex primary and secondary spherical mirrors, Vixen's improvement of Maksutov's design is the incorporation of a 2-element corrector lens in front of the secondary mirror.

This system tidily corrects spherical aberration and field curvature. It also eliminates the need for a big, expensive and heavy front corrector plate found in conventional Maksutov designs.

In addition, the resulting open tube design excludes the possibility of dew condensing on a full-aperture corrector.

Focusing is via primary mirror movement and optical collimation is accomplished by secondary mirror adjustments, just like on the smaller Schmidt-Cassegrains telescopes many amateurs are accustomed to.

The VMC330L OTA comes supplied with 2" eyepiece adapter, dual T-thread flip-mirror with dual 1¼" eyepiece adapters, 7x50mm finder and carry handle. Optional tube rings (#5625) and dovetail bar are available.
