Stellarvue has been producing refractor telescopes since 1998. Our new SVX telescopes are made with optics we hand-figure at our shop here in Auburn, California. These are the finest and most accurate telescopes we have ever offered. When you purchase an SVX series refractor, it will come with its own Zygo interferometric test report taken at full aperture in our shop, documenting the accuracy of your individual objective. To learn more about what we do, watch the following video: Sky & Telescope's Dennis DiCicco visits Stellarvue.
