Description

Details

Sky-Watcher has opened a portal to the stars with the new Stargate 18" Truss-Tube Dobsonian telescope. This telescope 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 total light gathering power of 4266x and a maximum useful magnification of 914x, you will find that the Sky-Watcher Stargate 18" Dobsonian makes it easy and enjoyable to scour planetary and deep sky visual targets for the most refined and subtle of details. Sky-Watcher aproximates this telescope to have a roughly thirty minute setup time due to how easily assembled it is; a factor that, when combined with it's low weight of 110lbs compared to its size class, makes this a great scope for taking out to local star parties or dark sites despite its immense power and size; it's simply designed in that efficient of a method.

And of course, it's not just raw power and convenience that Sky-Watcher prioritized when designing and making the Stargate 18". 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 that primary mirror, is heavily multi-coated with high quality Silicon Dioxide coatings that ensure optimal durability and performance.
