DOB 12" SynScan
Product Features

The Sky-Watcher Dobsonian SynScan series is precision engineered instrument that will allow you to easily find and enjoy viewing night sky treasures, such as Planets, Nebulae, Star Clusters, Galaxies and much more. With its patented collapsible tube design, these Dobsonians are truly the ultimate in portability and performance. Ultimately, Dob SynScan combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized Go-To telescope.

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 SynScan AZ hand control allows you to 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 Freedom Find (dual-encoder) technology allows the telescope to be moved manually whenever the user wishes - but with no need for re-alignment!

Freedom Find™ - tracking made easy!

With the patented Freedom Find (dual-encoder) technology which allows the telescope to be moved manually or electronically in either axis without losing its alignment or positional information. After moving to a new object the telescope will automatically begin to track the new object accurately. No re-setup is required in one observing session.

"Sky-Watcher’s GoTo Dobsonian
High-tech meets bargain-telescope design. A shotgun marriage or a match made in heaven? We find out!"

"Could the new Sky-Watcher SynScan telescopes really work? doubts were allayed the first night out.Our test telescope,on loan from Pacific Telescope Corp., worked great. Surprisingly so."
