SkyWatcher ProView 80ED with AllView Mount.
Includes Limited Two Year Warranty
. . The SkyWatcher S20160 provides a complete rig for near-space and deep-sky observation or astrophotography/astroimaging. The optical tube assembly (OTA) features a doublet apochromatic lens system made of extra-low dispersion glass that virtually eliminates chromatic and spherical aberrations. This creates views that are clear and bright with true high-contrast color rendition without distortion or "comas".
Complementing the lens system are fully multicoated optics with Sky-Watcher's Metallic High-Transmission Coatings (MHC) that maximizes light transmission. To achieve ultra-precise focusing, the Pro80ED is equipped with a 2" Crayford two-speed focuser. Unlike conventional rack-and-pinion focusers, a Crayford uses a tension system to press the focusing rod against the draw-tube enabling precise control of the focus without backlash. Two 1.25" eyepieces, a 1.25" eyepiece adapter, and a 2" 90° star diagonal come with the OTA.
