The Vixen VMC200L Telescope OTA with Sphinx SX2 Equatorial Mount and Star Book One is well suited to deep sky observing and imaging. This 8.0"/200mm f/9.75 catadioptric telescope features a sophisticated configuration that employs incorporates a primary mirror and a meniscus corrector just before the secondary mirror. The resulting optical path is corrected twice - this eliminates spherical aberration and field curvature while delivering sharper images without false-color. Because the optical correction is placed before the second mirror, there's no need for a corrector plate and the dewing problems associated with it. Another benefit is the elimination of spherical aberrations.
Focusing the VMC200L yields a stable and easy to adjust image. The rack-and-pinion focusing system is placed behind the primary mirror to eliminate image-shift. The focuser accepts 2.0" eyepieces and accessories.
This package includes the VMC200L telescope, Vixen's SLV 9mm and 20mm eyepieces,a 7x50 finderscope with a flip mirror diagonal that accepts 1.25" eyepieces, the Sphinx SX2 mount with the Star Book One, and the SXG-HAL130 aluminum tripod.
