Product Description
Sky-Watcher’s Flextube SynScan GoTo Collapsible Dobsonian series are the telescopes your mother warned you about. Big aperture, bigger attitude, with all the innovations that make Sky-Watcher the obvious choice when hunting for that Goldilocks zone where value meets desire.
Ranging from the standard 8 to a whopping 16 inches in diameter, Flextube SynScan Dobsonians are precision engineered instruments that will allow you to easily find and enjoy viewing night sky treasures such as planets and the Moon, nebulae, star clusters, galaxies and much more. With its patented collapsible tube design, these Dobsonians are truly the ultimate in portability and performance which is crucial when travelling to dark skies to make the most of these impressively large telescopes.
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 Flextube Dobsonian does not need to be disassembled between uses. It transports as two compact pieces (optical tube and rocker box) 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 and even after being collapsed! 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 patented Freedom Find dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need for re-alignment!
The SynScan hand controller allows you to point your telescope to a specific object, or even tour the best objects in the night sky at the touch of a button!! The user-friendly menu system allows automatic slewing to over 42,900 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions.
The Flextube SynScan series seamlessly combines the convenience and affordability of the traditional Dobsonian with the performance and precision of a computerized GoTo telescope all to help you in your quest for big aperture views.
