  • Description

    A superior modified Cassegrain design, the Vixen VMC260L telescope outperforms a traditional Schmidt-Cassegrain. The Japanese-made Vixen VMC260L Reflector is a true all-purpose telescope. Despite its long focal length, the tube is only about 20" long.  As a result, the instrument is very portable. With its large 10.2" aperture, the VMC260L Modified Cassegrain collects enough light for serious planetary and deep sky observing and imaging.  The VMC design consists of two mirrors and a double meniscus corrector lens, and does a great job of eliminating spherical aberration and field curvature while delivering superb contrast. Focusing is through primary mirror movement.  The Vixen VMC260L Reflector features Dielectric Coated Mirrors for brighter, sharper images. The VMC260L has very good contrast. It is an excellent telescope for observing globular clusters, double stars and distant planets. With its open tube design, the telescope cools down quicker than a classical Cassegrain.

    The Vixen VMC260L Modified Cassegrain is ideal for high grade astro imaging. The meniscus correcting lens offers a large corrected field. Light coming from the object is reflected off the primary mirror (f/2.5) and then passes through the corrector plate in front of the secondary mirror. This correcting lens is responsible for the large usable field of the VMC260L. With the optional reducer you get shorter exposure times. The basic configuration already contains a piggy-back camera holder. You can take photos both through the telescope and using a telephoto lens parallel to the main instrument, or use the VMC260L for guiding while the camera sits on top.
