The elegant truss tube design was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the SkyWatcher Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening! The patented Tension Control Handle allows users to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboards.
The Autotracking Dobsonian features a patented setup method that does not require polar alignment. The dual encoder design allows instant precise tracking of celestial objects: the telescope can be moved by hand whenever the user wishes - but with no need for re-alignment! The Sky-Watcher Autotracking Dobsonian Series combines the convenience and affordability of the traditional Dobsonian with the convenience of accurate real-time motorized tracking.
