Sky-Watcher SKU: S21120 | Helix SKU: CTS21120
Sky-Watcher’s AZ-GTi is the perfect tracking platform for those seeking a compact travel mount capable of both Alt-Az Go-To alignment and video timelapse. Boasting a payload capacity of 11lbs, this modular AZ mount can support anything from a small Maksutov or refractor, to a mid-sized DSLR for timelapse photography. Weighing just 8.6 lbs, the AZ-GTi is the ideal travel mount, easily fitting in carry-on luggage and perfect for grab-and-go situations.
The AZ-GTi is one of the first Sky-Watcher products featuring built in WiFi control. Once connected to the mount, use Sky-Watcher’s SynScan Pro app to align the mount for celestial tracking or the SynScan PTZ app for timelapse photography.
The AZ-GTi includes an adjustable aluminium tripod with built in pier extension. The mount can attach to a tripod using a 3.8”-16 thread and includes an adapter for ¼”-20 thread sizes, making it capable of mounting to nearly any tripod.
No need for an intervelometer timer with the AZ-GTi! With a 60-second preset exposure setting, the AZ-GTi can trigger a DSLR using the auxiliary shutter release cable. Once the camera is plugged into the mount and a shot is fired, it will continually shoot 60 second exposures until the cable is removed.
The 102mm OTA comes with a red dot finder, 1¼ inch diagonal and Super 10 and 25mm eyepieces.
The AZ-GTi come with the mount head, pier extension and tripod.

Sky-Watcher SKU: S11920 | Helix SKU: CTS11920
Stargate's 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.
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.
Our GoTo line of Stargates 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.

The exciting new Starlux Mak-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for.
The Mak-Newtonian design provides large aperture apochromatic performance with exceptional field correction in a compact, affordable package. Compared to a similarly sized Schmidt-Newtonian, the Mak-Newtonian yields a sharper image with more contrast. Naturally, the Mak-Newtonian is an excellent visual performer, too.

This Sky-Watcher 102mm (4") f/5 telescope is a two-element, air-spaced, fully multi-coated objective, achromatic refractor, which can give exciting "rich field" astronomical views. It can provide excellent vistas of star fields, clusters, nebulae, galaxies, planets, the Moon and (with correct filtering or by projection) the Sun. It is also a fine terrestrial telescope when mounted on an alt-azimuth mount or a photographic tripod.
Crisp images at a reasonable price make it an excellent beginner's "first telescope", or a great travelling telescope for a more advanced observer. Similar to the popular 80mm f/5 refractor, this larger aperture model has more light collecting power at the same focal ratio and accepts 2" diagonals for awesome wide field views, while only a small amount of chromatic aberration and weight.
Weighing about 3kg. (6.5lbs.) the optical tube assembly is readily carried and with a compressed length of approximately 50cm (21.7") it is easily transported. Being a refractor, it is quick and easy to set up and the low- maintenance, enclosed optics come fully collimated from the factory.
The optical tube assembly comes with "tube mounting rings". These hinge open to allow easy installation of the optical tube and the locks can be loosened during use to allow tube rotation and balancing. Mounting the telescope on an alt-azimuth or an equatorial mount is quick and simple with the appropriate mounting plate. This telescope also performs well as a fixed aperture, 510mm lens for both terrestrial and astrophotography.
The "fast" f/5 focal ratio, combined with today's high-speed films, is excellent for capturing lunar and solar eclipses as well as for nature photographs. A solid, equatorial mount and a method of guiding are required for longer exposure astrophotography. A T-mount thread on the eyepiece holder allows direct attachment of an appropriate T-adapter and the optional extension tube gives closer focusing for terrestrial photography.
