Skywatcher Skyliner Autotracking 250p Dobsonian
The Skywatcher Skyliner autotracking 250p Dobsonian is a revolutionary new collapsible Dobsonian that allows automatic tracking of celestial objects without complicated set-ups and adds the ultimate in portability and performance.
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.
Tension Control Handle
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.
It combines the convenience and affordability of the traditional Dobsonian with the convenience of accurate real-time motorized tracking.
The 250p Dobsonian is also available in a computerized version that makes locating astronomical objects fun and easy. Using the renowned SynScan computer controller users can select objects to view from a database of over 40,000 celestial sights. Just select an object, press 'enter' and watch the telescope automatically find and track the object for you.
