This is the latest version of our 130 mm apo triplet refractor. Two important factors make this lens superior:

1. This model uses a unique lens design that provides excellent sphero-chromatic correction using an extra low dispersion center element and a very expensive Lanthanum rear element. This lens has a unique glass combination that delivers color free, high contrast performance.

2. 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. Special tools are made and experienced opticians hand figure objectives here in our optical shop in Auburn California. While our former models (without the X designation) were all excellent coming in at .95 Strehl or higher, SVX series telescopes are even more exceptional, placing 98 - 99% of the light precisely where it should be. Stellarvue Premier (X) Series refractors are for the astronomer who recognizes the best when they see it. Each SVX series refractor comes with a Zygo interferometric test report taken in our shop, documenting the accuracy of your objective!

cell-cte-400.jpgMore: Air spaced lenses that are 5" and larger are often mounted in aluminum cells. These cells expand and contract many times more than the glass. The larger the lens is, the more important it is to have it mounted in a cell with a similar coefficient of expansion (CTE). LZOS in Russia has always provided their 130 mm and larger lenses in a steel cell for this reason. Many other 127 - 130 refractors use simple aluminum cells which expand and contract around the glass many times more than our cells, distorting the image. Using a material that closely approximates the expansion and contraction rate of the glass is heavier and much more expensive but it maintains the performance of the lens despite dropping temperatures. 

The SVX130 is a full triplet apo. Expect zero false color, high contrast and an exceptional star test.

Our new 3.5" dual speed rack and pinion focuser comes with draw tube rotator to provide more accurate rotation when imaging. We enhance the performance of these focusers by using bearings that have no slop when properly adjusted. The 3.5" aperture significantly reduces vignettng seen in 130's with smaller focusers.

We use American made CNC mounting rings, a retracting dew shield, metal dust cap and protective case. 

The Stellarvue C130L comes standard with the SVA130T. This is our largest heavy-duty soft case. It is made of the same rugged material construction as our other thickly padded travel cases. Outside dimensions are 39" X 10 1/2" X 101/2". Inside dimensions are 36" X 8" X 8".  Has two internal dividers that are held in place by velcro and can be easily removed.
