Celestron Skywatcher 8" Dobsonian Telescope - Tube Only

Model: S11700-1. The Sky Watcher 8 Inch Dobsonian Telescope Tube has an 8x50mm Right Angle optical viewfinder that provides both magnification and light-gathering to help narrow your search for the stars.To guarantee mechanical ease-of-use, the Sky Watcher 8" Dobsonian S11700 uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to assist in setting the appropriate amount of friction, while making smooth vertical and horizontal manual movement without any interference from small bumps or gusts of wind. The Sky-Watcher telescope uses a revolutionary truss-support concept which allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece, low-hassle OTA design is mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by one individual.This telescope uses quality components throughout with a pride of workmanship in high quality standards of optical and mechanical construction. The polishing process for the primary and diagonal mirror provides smooth mirror surfaces to assure good contrast. On each primary mirror and elliptical diagonal mirror, aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz. Additional layers of Titanium Dioxide and hard quartz are then applied.
