    Sky-Watcher 20" Stargate Truss-Tube Dobsonian

    Sky-Watcher has opened a portal to the stars with the new Stargate 20" Truss-Tube Dobsonian telescope. This telescope was designed for immense light gathering power and ease of use, and is sure to deliver on both fronts for the most discerning of visual astronomers. With a maximum useful magnification of 1000x, you will find that the Sky-Watcher Stargate 20" Dobsonian makes it easy and enjoyable to scour planetary and deep sky visual targets for the most refined and subtle of details. The Stargate 20" is somewhat larger than its 18" sibling, but Sky-Watcher still estimates that it should take no longer than thirty minutes for an experienced astronomer to assemble and render it ready for observational use under normal circumstances.

    And of course, it's not just raw power and convenience that Sky-Watcher prioritized when designing and making the Stargate 20". They also made sure to include a primary parabolic mirror design that eliminates the spherical aberrations that are otherwise inherent in faster focal length reflectors. These mirrors are designed to bring all of the light your telescope has gathered to a single focal point and ensure sharp, high contrast, high detail images. Every optical mirror in the Stargate, including the parabolic primary mirror, is fully multi-coated with high quality Silicon Dioxide coatings that ensure optimal durability and performance.
