This is the imaging system version of the SVX130T-WR35. It includes the Moonlight focuser version of the SVX130T and the giant .72X reducer/flattener.
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!
This is our highest resolution telescope which performs flawlessly as a visual or photographic instrument. To use it photographically, order the correct field flattener or field flattener/reducer (see below). The amazing Moonlite 3.5" focuser has short focuser travel to hold even the largest/heaviest accessories without strain. Numerous large extension tubes allow for various accessories to be used and it comes with both a visual back for 2" eyepieces, a 1.25" adapter and a threaded M75X1 adapter for use with various Stellarvue photographic field flatteners. This focuser can be used manually or with a hand control.
Stellarvue Premier SVX Optics:
More: 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.
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.
Free shipping: Order now and when ready the telescope will ship free to the lower 48 states only. We will ship by either UPS Ground or Fed Ex Ground. You can upgrade shipping methods by paying the difference. Call us at (530) 823-7796.
Tax: No tax is charged when sold and shipped outside of California. If you live in California in a high tax zone call us at (530) 823-7796 and ask about our California tax discount. Yes, death and taxes are not avoidable but we can help you by giving you a "California Discount" to offset the pain.
OPTIONAL VISUAL ACCESSORIES
You will need a star diagonal, eyepieces, mount and tripod to observe with this telescope. You will find a finder scope helpful in locating objects. We recommend the following:
Diagonal: Optional. Please note, you can purchase our best 2" diagonal above and save $50.
Eyepieces: Optional. We recommend our best eyepieces for this telescope, a complete set of the Stellarvue Optimus.
Mounts: For strictly visual use the M002CS is a basic alt az mount that will hold the SVX130T with stability.
For imaging we recommend:
Paramount MYT. This is a great choice for accurate long exposure imaging.
A field flattener or reducer flattener turns your SVX130 into a stunning astro-graph.
