Why we love the Sky-Watcher StarTravel 102 AZ-GTe Refractor Telescope (S21160)
Product Description
This Startravel 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 provides 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.
Rich Field Astronomical Views
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 adding a small amount of chromatic aberration and weight. Being a refractor, it is quick and easy to set up and the low-maintenance, enclosed optics come fully collimated from the factory.
Revolutionary Wi-Fi Control
Download the free SynScan Pro app to control the AZ-GTe with your smartphone. Available for both iOS and Android
Easy Integration with any Tripod
The AZ-GTe includes an adjustable aluminum tripod with built in pier extension. The mount can attach to a tripod using a 3.8-inch-16 thread and includes an adapter for ¼-inch-20 thread sizes, making it capable of mounting to nearly any tripod.
Automatic Shutter Release Control
No need for an intervelometer timer with the AZ-GTe! With a 60-second preset exposure setting, the AZ-GTe 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.
Ultra-Compact
Weighing just 8.6pounds with pier extension and tripod, the AZ-GTe carries a full 11-pound payload, making it a great grab-and-go mount
The Sky-Watcher AZ-GTe series is for anyone looking for a small, powerful mount. Weighing just 8.6 pounds, complete with pier extension and tripod, these versatile mounts support a hefty 11-pound payload.
