TAL-200K 8.5 is the latest model of the Klevtsov/Cassegrain designed telescope. The latest design changes that differentiate this model from older ones are a reduced focal ratio from f10 to f8.5, and addition of a smooth-friction Crayford Focusing mechanism, instead of the Rack and Pinion type used in early models. Also, primary mirror correction is possible now without removing the focusing mechanism during a simple star test. Portable design with a superior Klevtsov optical scheme and durable construction allows you to take this powerful telescope with you on the road, easily and worry-free. Klevtsov's revolutionary catadioptric design employs a sub-aperture meniscus correcting lens (like the familiar Maksutov) combined with a Mangin mirror-lens secondary. Diffraction artifacts are well controlled by unique curved spider vanes. OTA is made from an aluminum alloy.
