Sky-Watcher SynScan Dobsonian Mount for 10\"

If you have a Skywatcher 10" Dobsonian that you'd like to upgrade to full GoTo capability, the Sky-Watcher SynScan computerized Dob mount is the perfect solution. It includes all components required to easily transform your Sky-Watcher Dob. You just need to replace the left side altitude bearing with the included part, and drop the telescope into place.

For other telescopes that do not exceed the maximum tube diameter, with a little ingenuity one can fashion a suitable right side altitude bearing.

The computer drive system is rather clever. If you nudge a traditional computerized telescope, the computer has no clue that you moved it, and how far. Not so with this dob.

The closed-loop system incorporates motor drives and high resolution optical encoders coupled to each axis providing accurate slews, while registering all movement - even if you push the telescope out of position.

Sky-Watcher computerized Dobsonians support a GPS receiver (sold separately). This plug-in module will set your time, date, longitude and latitude automatically based on the Global Positioning Satellites orbiting the Earth. You can also plug this GPS receiver into your PC's USB port to add geo location capabilities. One possible use is contributing to the Open Street Mapping project.
