Synscan Puts The Universe In Your Hands

Sky-Watcher Stargate Mirror

Stargate Dobsonians provide motorized operation in both alt and azimuth axes. Featuring Sky-Watcher’s proprietary SynScan hand controller, your scope now automatically slews to and tracks over 42,900 celestial objects from the on-board database.

Sky-Watcher’s Freedom Find™ dual-encoder technology ensures accurate tracking while allowing you to move the telescope manually in either axis without compromising alignment. This provides a level of convenience and flexibility not available in telescopes without dual encoders.

Innovative Lightweight Mirror Design

Stargates feature Sky-Watcher’s exclusive fused conical parabolic mirrors. The fused design allows for thinner mirror construction that provides faster cooling and lighter weight.

Combined with the cast cellular secondary mirror and Sky-Watcher’s exclusive 94% reflectivity coatings, Stargate delivers bright, detailed views of your favorite deep sky objects. The 18 inch model captures 27% more light than our 16 inch, while the 20 inch (a full half meter of aperture) boasts a monster 56% more light gathering power.

Solid Foundations, Easy Assembly

The minimalist all-metal structure of the Stargate produces a sturdy and stable platform while maintaining a convenient and compact footprint. The truss-tubes break down to a very manageable 36 inch length for easy transport. Azimuth and altitude bearings are steel and Teflon for smooth, steady movement.

Setting up a Stargate is a simple procedure, taking only about 20 minutes. Spring loaded truss anchor points are clearly labeled to eliminate any frustration or confusion. Adjustable feet make leveling a snap.
