Sky-Watcher’s all new Virtuoso GTi collapsible tabletop Dobsonian is the ultimate combination of convenience, flexibility, and light-gathering power – now with Wi-Fi! Ideally suited for both the beginner astronomy enthusiast looking for a first telescope and as a casual backyard/travel alternative for the experienced observer, this small scope boasts big views and is the perfect camping companion for your dark sky getaways.
Available in either 130 or 150mm apertures, the Virtuoso GTi has undergone a major transformation from the original Sky-Watcher Virtuoso mount in all the ways that matter: Larger aperture, faster focal ratio, a collapsible OTA, and built-in Wi-Fi for full GoTo telescope control via a smartphone and Sky-Watcher’s free SynScan app for iOS and Android. While the original Virtuoso from Sky-Watcher was more focused on planetary, solar, and lunar viewing with its long focal length and included solar filter, the all-new Virtuoso GTi borrows its collapsible optical tube design from the popular line of Flextube and Heritage Sky-Watcher Dobsonians for a versatile package that does it all.
Virtuoso GTi features Sky-Watcher’s Radiant™ Aluminum Quartz (RAQ™) coatings on all optical surfaces for bright, bold views and comes complete with everything you need to start exploring the night sky mere minutes out of the box including a red dot finder and two eyepieces (25mm and 10mm). With the free SynScan Pro app – available for iOS and Android -- the user has access to a database that contains over 10,000 objects, including Messier, NGC, IC, and Caldwell catalogs. Align on the stars using one of four alignment methods to put Virtuoso’s internal GPS to work and track objects like the Sun, Moon, and stars at precise rates. Patented Freedom Find™ technology uses dual encoders to allow manual control while retaining alignment.
The VIRTUOSO GTi Dobsonian Mount – WiFi-controllable with iOS and Android and compatible with syncs hand controller, allowing it for smooth tracking and alignment. Use Wifi to control the telescope wirelessly with your mobile device; smartphone or tablet.

About Sky-Watcher
Sky-Watcher was launched in 1999 featuring a modest line of Newtonian and refractor optical tubes, with distribution in Europe and Asia. In 2000, Sky-Watcher released their first series of Dobsonian telescopes, and two years later answered the rising popularity of digital SLRs with their first version of the famed German Equatorial Mount, the EQ6. Today, with a full product line that includes Dobsonians, APO refractors, EQ mounts, and photography products, Sky-Watcher has grown into the most popular telescope brand worldwide.
