 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. |
