TAL 200K Telescope

Based on a novel optical design by Klevtsov, the versatile TAL-200K is the ideal instrument for the advanced amateur astronomer who desires high resolution and excellent light-gathering power (limiting visual magnitude 13.5) in a highly portable telescope.

The TAL-200K provides an aperture of 200mm and focal length of 2000mm in a very compact tube length of only 550mm (22 inches). Klevtsov's revolutionary catadioptric design employs a sub-aperture meniscus correcting lens (like the familiar Maksutov) combined with a Mangin mirror-lens secondary. Its fast focal ratio of f/10, flat field, and excellent correction of coma, spherical aberration, and astigmatism (14 micron star images at a distance of 10mm from the optical axis!) make the TAL-200K a superb instrument for astrophotography, far surpassing conventional Schmidt-Cassegrain and Ritchey-Chretien systems. Every optical component must pass stringent tests. Interferograms on three axes of each optical set are retained by the factory's quality control department.

The telescope is supplied with an 8x50mm finder with a 7 degree field of view, an equatorial mount with motor drive in Right Ascension and manual slow-motion in Declination, two eyepieces of 25mm and 10mm focal length, and a 2x Barlow lens.

To comfortably observe objects near the zenith, a diagonal mirror which diverts the light path by 90 degrees is also supplied, as well as an adaptor for 35mm SLR cameras. All surfaces of the refractive elements have anti-reflection multi-coatings for maximum light throughput. The TAL-200K is a remarkbly compact, easy-to-use instrument that will meet the requirements of the most demanding amateur astronomer.
