Lightweight and portable Wi-Fi GoTo alt-azimuth mount with a 5 kg payload capacity. The Sky-Watcher AZ-GTi features Freedom-Find dual encoders, a 45 mm saddle and an adjustable aluminium tripod.
Compact and highly portable, the Sky-Watcher AZ-GTi is a GoTo alt-azimuth mount featuring built-in Wi-Fi for wireless control from a smartphone or tablet.
The mount creates its own Wi-Fi network, allowing it to operate without relying on an external network. Control is provided through the free SynScan app for iOS and Android.
After entering the observing coordinates and completing the alignment procedure, the GoTo system can automatically slew to objects contained in the SynScan database of more than 10,000 celestial objects.
The patented Freedom-Find dual-encoder technology also allows the telescope to be moved manually on either axis without losing positional information. Users can therefore switch freely between manual movement and motorised control during an observing session.
With a 5 kg payload capacity and a 45 mm Sky-Watcher/Vixen-type saddle, the AZ-GTi provides a compact mounting solution for compatible instruments.
This version is supplied with an adjustable aluminium tripod and accessory tray.
Built-In Wi-Fi Control
The Wi-Fi module is integrated directly into the mount.
The AZ-GTi creates its own wireless network, allowing it to be used in the field without a router or connection to another Wi-Fi network.
Control is provided through the SynScan app for iOS and Android.
A SynScan hand controller can also be used but is available separately.

Its database contains more than 10,000 objects, including:
• 10,759 deep-sky objects
• Messier, NGC, IC and Caldwell catalogues
• Named deep-sky objects
• 305 named stars
• 55 double stars

Compatible third-party planetarium software allows access to objects beyond the SynScan database.
Alignment Methods
The SynScan app includes:
• Brightest Star Alignment
• North-Level Alignment
Additional SynScan Features
The app also provides:
• Tonight’s Best Sky Tour
• Point and Go with a mobile device
• Celestial object identification
• Remote control over the Internet
• User-defined objects

Freedom-Find Technology
The patented Freedom-Find system uses auxiliary axis encoders.
It allows the telescope to be moved manually without the mount losing its positional information.
Motorised control and GoTo operation can then be resumed without repeating the alignment procedure.
