This R200SS 200mm f/4 Reflector Telescope with SXP2 Mount from Vixen Optics has a chromatic, aberration-free, Newtonian reflector that can resolve and split distant binary stars and separate individual stars in clusters. Its large aperture and moderate focal length results in a fast f/4 focal ratio ideal for observing and imaging the moon, planets, and deep-sky objects including galaxies, clusters, and nebulae. The R200SS is offered here without a tripod or mount head for those who already have a reliable rig and are looking to upgrade or add to their observation capabilities.Optical PerformanceAperture: 200mm (8")f/4 focal ratio800mm focal lengthNewtonian reflector optical pathAntireflection multicoated optics for increased light transmission and overall image contrastResolution: 0.63 arcsec, RayleighRack-and-pinion focuser resists flexing or bending under heavy weights60mm and 42mm for T-ring mount threads for prime-focus astrophotography1.25" visual back for observations using the most common-sized eyepieces and accessoriesFinderscope7x magnification with wide field of view for alignment and star-hop navigationLarge 50mm apertureIlluminated crosshair reticle for properly centered objectsAdjustable intensitySXP2 MountThe features of the SXP2 mount include pulse motors and a belt drive system, a generous use of bearings, P-PEC, meridian crossing and disabling reverse motion, and more.
