Sky-Watcher 12" Computerized Collapsible Dobsonian Telescope
The 12" Sky-Watcher Dobsonian SynScan is a large aperture, precision engineered telescope that will allow you to easily find and enjoy night sky treasures like Saturn, Jupiter, and other planets in the solar system, plus a huge array of deep-sky objects including galaxies, star clusters, nebulae, and more. The collapsible tube design turns what would be a fairly unwieldly telescope into a portable one! The Dobsonian mount can usually ride in the backseat of most vehicles, but it is the length of the tube assembly that can cause trouble. With the collapsible trusses on board, however, you have the ability to shorten the OTA by half without requiring that you remove the trusses! It's almost magic!
The elegant truss tube design of the Sky-Watcher S11820 Dobsonian 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 and allowing the telescope to stay where you put it for as long as you like.
The Sky-Watcher SynScan™ AZ hand control allows you point your telescope at a specific object, or even tour 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 patented dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need for re-alignment!
The Sky-Watcher 12" SynScan Dobsonian combines the convenience and affordability of the traditional Dobsonian with the high-tech features of a computerized Go-To telescope.
