Sky-Watcher AZ-GTiX dual-saddle mount and tripod

An app-controlled, lightweigh­t setup that offers double the mounting capacity

- WORDS: PAUL MONEY

e’re used to seeing equatorial mounts of varying sizes and capacities, along with equatorial tracking mounts for lightweigh­t setups and ease of transport. Here we explore the latest offering from Sky-Watcher that does away with the need to polar align and instead provides a lightweigh­t portable altaz mount, the AZ-GTiX.

Our review package included the AZ-GTiX mount and tripod with extension pier, plus an L bracket for attaching either a camera or another telescope. This mount is a dual-saddle mount, one where you can have two telescopes or a combinatio­n of equipment on just one mount. Its load capacity enables one lightweigh­t telescope up to 6kg on one saddle or up to 10kg total weight if using both saddles.

The mount has an integrated Wi-Fi adaptor to provide its own network so that you can control the mount via the downloadab­le SynScan app or, if you prefer, you can attach an optional SynScan hand controller. For our tests we operated it as intended via the app, which is suitable for iOS or Android operating systems.

Power is provided either by eight AA-type batteries nicely hidden away in the body of the mount or via an external power supply, such as the typical power tanks provided for astronomic­al mounts. For our tests we used batteries and despite extensive testing during a particular­ly cold spell, the mount was still operationa­l at the end of the review period. That’s really good news for anyone wishing to use this in the field at a remote dark-sky site.

The versatilit­y of the AZ-GTiX mount with its dual saddles meant we could set it up either with a single telescope, single camera setup, camera and telescope, camera and camera with different lenses, or two telescopes. With the telescopes, we could use one for viewing and one for astrophoto­graphy. We also set it up during daytime for solar viewing with a hydrogen-alpha telescope on one saddle and a white-light telescope on the primary saddle – useful, for example, for public events around a solar eclipse.

Attachment of the mount to the tripod is via a 3/8-inch thread, so photo tripods can be used; you can buy the mount without a tripod if you already own something suitable. We found the tripod supplied for our review perfect for the mount and

the supplied extension pier added a little extra clearance for longer-focal-length telescopes, so they don’t catch on the tripod legs.

Initial setup involved aiming the mount with our telescope level and pointing north, then powering up and connecting the SynScan Pro app via the mount’s Wi-Fi network. In the settings, we ensured the app had fixed upon our location and then all that was needed was to perform a star alignment. Using our Equinox 80ED refractor and 26mm eyepiece, we then proceeded on a tour of over 20 targets in the winter sky, with almost all centred close to the central 50 per cent of the view.

We placed a camera and large lens on one saddle and the telescope on the other and centred it on M45, the Pleiades star cluster, leaving it tracking while the camera took exposures and we periodical­ly checked the view. The mount kept M45 at the centre of the view for 50 minutes, and the images we later processed showed that you can do astrophoto­graphy with this mount with short exposures. We also tested the AZ-GTiX’s Point and Track feature, whereby without alignment you start up and aim the telescope at your target and leave it tracking. We did so on the Moon and, again, 20 minutes later it was still centred.

Overall, we were very impressed with this lightweigh­t mount and found we quickly turned to it first for our observing and imaging sessions. We can highly recommend it.
