The Sky-Watcher Dobsonian Flextube 12" Go-To & Wi-Fi collapsible combines the great light gathering of the Dobsonian telescope with the convenience of the computerised system SynScan. Once the telescope is aligned, the Go-To system allows the user to slew the telescope towards planets, stars, nebulae, galaxies, clusters and much more.

The SynScan has 42,900 celestial objects in its memory, allowing for an amazing journey of the night sky. The Deep Sky Tour function suggests a list of the most interesting deep sky objects so even the beginner astronomer can easily observe faint objects with a touch of a button. Now it is even easier to control SkyWatcher go-to Dobsonian thanks to the embedded wi-fi system. Download the SynScan App on your iOS, Android or Windows device and control your telescope remotely.

The patented collapsible system is the ultimate in technology and portability and is ready for night sky action in seconds; the spring loaded system enables an easy, single handed extension of the tube.

The Freedom Find technology (dual-encoder) allows the telescope to be moved manually whenever the user wishes, but without losing any of the pre-set alignment.

To top it off, the Sky-Watcher Collapsible Dobsonians are equipped with a 2″ Crayford focuser and focuser locking screw.
