Perfect for any Situation Sky-Watcher’s AZ-GTi is the perfect tracking platform for those seeking a compact travel mount capable of both alt-az GoTo alignment and video timelapse. Boasting a payload capacity of 11-pounds, 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-pounds, the AZ-GTi is the ideal travel mount, easily fitting in carry-on luggage and perfect for grab-and-go situations. Revolutionary WiFi Control The AZ-GTi is one of the first Sky-Watcher products featuring built in Wi-Fi control. Once connected to the mount, use Sky-Watcher’s SynScan Pro app to align the mount for celestial tracking. Easy Integration with any Tripod The AZ-GTi 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-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. Included Accesories The 127mm OTA comes with a red dot finder, 1.25-inch diagonal, and Super 10 and 25mm eyepieces. The AZ-GTi come with the mount head, pier extension, and tripod.
