Sky-Watcher Traditional Dobsonian 10 inch

Its large parabolic primary mirror is highly reflective and, corrects spherical aberration to eliminate distortion across the entire field of view, especially at the edges. The four-arm secondary mirror bracket is made with 0.5mm thick fine, supports to reduce light loss and diffraction spikes. Its f/4.7 focal ratio and Crayford focuser makes this an ideal choice for observation and, imaging - especially with larger or heavier rigs. The alt-az rocker mount features Teflon azimuth bearings and a tension clutch on altitude axis. The tension control handle allows users to adjust the settings allowing them to move the mount, easily and smoothly by hand with minimal vibration and maintain its position when released.
