Sky-Watcher’s all new Virtuoso GTi collapsible scope OTA is the ultimate combination of convenience, flexibility, and light-gathering power! 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 OTA has undergone a major transformation from the original Sky-Watcher Virtuoso in all the ways that matter: Larger aperture, faster focal ratio and a collapsible OTA. 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).

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.
