First-class precision instruments based on Klevzov's original advanced optical system design, for the advanced amateur astronomer who desires high resolution and excellent light passing power in a highly portable telescope. The Klevzov-Cassegrain non-aspherical system presents a radical new form of catadioptric telescope that combines the compactness of the short cathadioptric-Cassegrain with similar enviable high resolution image quality and contrast of modern Maksutov designs. Klevsov's revolutionary catadioptric design employs a sub-aperture meniscus correcting lens, combined with a Mangin mirror-lens secondary. Their fast focal ratios, flat field and excellent correction of coma, spherical aberration and astigmatism (14 micron star images at a distance of 10mm from the optical axis!!) makes these superb instruments for astrophotography, as well as for the observation of planets and deep-sky objects. The TAL-150K provides an aperture of 150mm and focal length of 1550mm in a very compact tube length of only 315mm (12,4 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/10.3, 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-150K a superb instrument for astrophotography, far surpassing conventional Schmidt-Cassegrain and Ritchey-Chretien systems.
