Like the popular Schmidt-Cassegrain, the Vixen VMC is a true all purpose
telescope. Despite its long focal length the tube is only about 50cm (20%) long.
As a result the instrument is very portable. With its large aperture of 200mm the
VMC collects enough light for serious visual and photographical applications
both on the planets and on the deep sky. The VMC has a very good contrast. It is
an excellent telescope for observing globular clusters, double stars and distant
planets. With its open tube the telescope cools down quicker than an SCT or
classical Maksutov-Cassegrain.
Another strong point of this telescope is its capability for high grade astro
imaging. The meniscus correcting lens offers a large corrected field. With the
optional reducer you get shorter exposure times. The basic configuration already
contains a piggy-back camera holder. You can then take photos both through the
telescope and using a telephoto lens parallel to the main instrument, or you can
take the VMC260 for guiding while the camera sits on top.
Comes with 2" star diagonal, 2" wide angle eyepiece TS WA 42mm, Plossl
25mm, Plossl 10mm (Plossls are 1.25")
