Dobsonian Telescopes

The Dobsonian mounted telescope is popular among amateur astronomer and telescope makers because of its simplicity .The Sky-Watcher Dobsonian's patended Tension Control Handle allows users to add or reduce tension, there by increasing or decresing the friction between the optical tube and the side board of the mount. By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in posiotion but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be compltely tightened to lock the optical tube in position.
