"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? ...my doubts were allayed the first night out.Our test telescope,on loan from Pacific Telescope Corp., worked great. Surprisingly so."- Alan Dyer wrote in his 3-page review of the Sky-Watcher GoTo Dobsonian telescope at SkyNews November/December 2010 issue ([url=]www.skynews.ca[/url] | [url=]review[/url]).[url=]Read the 3-page article in PDF (580KB)[/url] |
The exciting new 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.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 SynScanTM 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 Dobsonian SynScan series combines the convenience and affordability of the traditional Dobsonian with the convenience of a computerized Go-To telescope.
