Skywatcher Dobsonian Telescopes

Sky-watcher Dobsonian Telescopes

The Sky-Watcher Dobsonians are alt-azimuth mounted designed telescopes popularized by the amateur astronomer John Dobson.

The SkyWatcher Dobsonians offer a "paraboloidal" primary mirror in their every model of telescope which eliminates spherical aberration and a four-arm, secondary- mirror bracket with fine supports, to reduce diffraction spikes and light loss.

The Dobsonian Telescopes or Dobsonian mounted telescopes are popular among amateur astronomers and telescope makers because of its simplicity. The Skywatcher Dobsonians' patented Tension Handle (US Patent No. 6,940,642) allows users to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount. The tension adjuster can tightened such that the optical tube can stay in a position but can still moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.
