Learn how to set up the Sky-Watcher AZ-GTi mount for GoTo astronomy, from tripod leveling to smartphone alignment. Includes tips for first-time users.
Quick Answer
Set up the AZ-GTi mount by leveling the tripod, connecting via the SynScan Pro app, and performing a two-star alignment to enable GoTo tracking.
Why the AZ-GTi Mount Works Well for Beginners
The AZ-GTi mount is a lightweight alt-azimuth mount with built-in WiFi, so you control it entirely from a smartphone or tablet. This eliminates the need for a hand controller or cables, making the initial setup less intimidating. The Freedom Find dual-encoder system lets you manually move the telescope without losing alignment, which is helpful when you want to nudge the view without redoing the alignment.
What to Know Before You Start
The AZ-GTi has an 11-pound payload capacity, so it supports small to mid-size telescopes. The included aluminum tripod has 1.25-inch legs and adjustable height. A stable, level tripod is critical for accurate GoTo slewing. If you order with SkyWatcher Free Shipping, the mount ships directly from the manufacturer; allow extra delivery time.
You will need the SynScan Pro app (free, iOS/Android). The mount creates its own WiFi network, so no internet connection is required during setup. Ensure your phone or tablet has WiFi enabled and that you are in a dark location to see stars for alignment.
Step-by-Step Setup Process
- Level and Position the Tripod: Set up the tripod on a stable surface. Extend the legs to a comfortable height and use the built-in bubble level to ensure the tripod head is level. Tighten all leg locks securely. An unlevel tripod will cause alignment errors. Double-check the bubble level after extending legs.
- Attach and Balance the Mount: Mount the AZ-GTi head onto the tripod and tighten the center bolt. Attach your telescope and accessories, then adjust the mount's clutches to balance the load. Lock the clutches once balanced. Over-tightening clutches can make manual movement difficult; they should be snug but not forced.
- Power On and Connect to WiFi: Turn on the mount using the power switch. On your smartphone, go to WiFi settings and select the network named "SynScan_xxxx". Open the SynScan Pro app and tap "Connect". If the network does not appear, power cycle the mount. The app may prompt you to update firmware; do this before proceeding.
- Configure Mount Type and Location: In the app, select "AZ-GTi" as the mount type. Enter your observing location manually or use the phone's GPS. Set the correct date and time (24-hour format). An incorrect time or location will cause the GoTo to point to the wrong part of the sky. Verify time zone and daylight saving.
- Perform a Two-Star Alignment: In the app, choose "Two-Star Alignment". The mount will slew to the first star. Center it in the eyepiece using the app's direction buttons, then tap "Align". Repeat for the second star. The app will confirm alignment success. Choose stars that are far apart in the sky (e.g., one east, one west) for better accuracy. Avoid stars near the horizon.
- Test GoTo and Start Observing: After alignment, select a bright object from the app's database (e.g., Jupiter, the Moon, or a bright star). Tap "GoTo". The mount will slew to the target. Center it manually if needed, then enjoy. If the target is not in the field of view, alignment may have been off. Repeat alignment with different stars or add a calibration star.
