Sky-Watcher Fusion 120i SynScan with Tripod GoTo Alt-Azimuth Mount

Designed to combine payload capacity, portability and wireless control, the Sky-Watcher Fusion 120i SynScan is a single-arm alt-azimuth GoTo mount capable of carrying an optical tube weighing up to 12 kg.

Its built-in Wi-Fi module creates its own wireless network, allowing the mount to be controlled from a smartphone or tablet using the free SynScan or SynScan PRO apps for iOS and Android without relying on an external Wi-Fi or mobile network.

Bluetooth provides a second wireless control option. A computerised SynScan handset is also supplied and provides access to a database containing more than 42,900 celestial objects.

Its dual-fit saddle directly accepts both 45 mm and 75 mm dovetail bars, allowing different optical tubes to be installed.

A rechargeable lithium-ion battery is built into the mount and provides up to 10 hours of tracking operation. An external 12–15 V DC / 3 A power supply can also be used.

This complete version is supplied with a stainless-steel tripod and accessory tray.
