Award-winning optics 
Sky-Watcher’s 94% reflectivity mirrors ensure you get bright and detailed views.
A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970’s. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity and ease of use.
The Sky-Watcher Dobsonian has a “paraboloidal” primary mirror to eliminate spherical aberration and a four-arm, secondary mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss. In addition, this model includes a 2-inch focuser with a 1.25-inch adapter, allowing the use of either eyepiece size. This model also includes the new feature-tension control handle.
