Stellarvue has been producing refractor telescopes since 1998. These new SVX telescopes are the finest and most accurate telescopes we have ever offered. SVX series optics are rated at .98 - .996 Strehl with excellent optical correction for aberrations commonly seen in mass produced optics. To attain this level of optical accuracy it is usually necessary for us to go beyond machine polishing. Experienced opticians hand figure objectives here in our optical shop in Auburn California. Stellarvue Premier (SVX) Series refractors are for the astronomer who recognizes the best when they see it as they have five times the correction and accuracy of our former objectives. 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 objective!
