Product Description
SVX130T Operators Manual: Click here for our online manual SVX130T
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 a super low dispersion (FPL-53 or equivalent) center element and a very expensive Lanthanum rear element. Compared to the former SVA130T, The SVX130T has much higher contrast and on average about five times the optical accuracy since these are hand figured in our shop in Auburn, CA. Most SVX130T's come in at above .99 Strehl!
2. SVX series optics are specified between .98 - .996 Strehl as tested on our in-house, 6" Zygo Verifer, phase shifting, laser interferometer. World class optics demand world class test equipment. As mentioned above, we have been exceeding our minimum standards. To attain this level of optical accuracy it is necessary for us to go beyond machine polishing. Special tools are made and/or experienced opticians hand figure objectives here in our optical shop in Auburn California. These lenses take about six months to perfect! While our former models (without the X designation) were all excellent coming in at .95 Strehl or higher, SVX series telescopes made this year place 99% of the light 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!
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 SVX130T 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.
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.
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:
Finder Scope: Optional. We recommend the F50W2 finder scope. The proper ring system for this finder is the R50DA ring system.
Diagonal: Available separately. Please note, you can purchase our best 2" diagonal above and save $50.
Eyepieces: Available separately. We recommend our best eyepieces for this telescope, a complete set of the Stellarvue Optimus. Save an additional $159 on the star diagonal and eyepieces when you select "
Mounts: For strictly visual use the M002CS is a basic alt az mount that will hold the SVX130T with stability.
For imaging we recommend:
Losmandy GM8-11G as a good portable tripod/mount and the G11 if you want the best stability.
Paramount MYT. This is a great choice for accurate long exposure imaging.
IMAGING ACCESSORIES
A field flattener or reducer flattener turns your SVX130 into a stunning astro-graph.
Field Flattener: Shoot at 910 mm focal length at f-7. Use the giant SFFX-2. This flattener produces an image circle over 60 mm in diameter! If you buy one with the telescope you save $200! Just select the option above.
Focal Reducer/Field Flattener: Shoot at 680 mm focal length f-5.25. Use the SFFRR.72-130-48. This redicer flattener produces an image circle over 40 mm in diameter. If you buy one with the telescope you save $200! Just select the option above. Save a total of $400 when you buy both of the photographic flatteners with the telescope and we will align both with the telescope before we ship it.

SVX130T
2019 marks my 55th year as an amateur astronomer since my father brought me to the Philadelphia Planetarium when I was 10 years old. During this period I have been fortunate to have owned the following high performance telescopes: Questar 3.5, Quantum 6, TEC 10" f12 Mak, Spica Eyes 22" Dob, Celestron 14, and several other telescopes. I also was an optical technician for the Celestron matching division where I had the opportunity to evaluate several thousand optical systems.
I purchased A Stellarvue SVX 130T serial # 009 in December 2018 and have had the opportunity to evaluate the telescope over the last several months.
Telescope mechanical construction:
Quite simply the construction of all elements of this telescope system is simply exquisite. The performance of the Stellarvue 3.5" dual speed rack and pinion focuser that comes standard with the telescope is every bit as good as the Feather touch focuser. The finish on the tube is beautiful, and several times before I have pulled the telescope out of its case, I have simply stopped to marvel at the exquisite beauty of the OTA assembly.
I ordered my scope with the Stellarvue highest grade quartz 2'" diagonal which I highly recommend. I also bought the Stellarvue 50mm finder scope and was simply blown away by the smoothness of its focuser, and the pinpoint star images it produced. I have never seen a better finder in all my years in astronomy.
Lastly I bought the entire set of Stellarvue Optimus eyepieces all of which have 100-110 degree FOV. At first, being a avid Nagler user for many years, I was thinking that these extraordinary fields of view would result in poor performance at the very edge of the field of view. I could not have been more wrong. Quite simply, and this is no exaggeration, the star were pinpoint right to the edge of the field. This performance, together with the 100-110 degree FOV, has resulted in the most exciting visual astronomical experience of my life.
I just returned from the 2019 GSSP in northeastern California. During that time I had the opportunity to observe Jupiter and Saturn side by side with several other high quality refractors and reflectors. Quite simply, there was a total absence of residual color, and the delicacy of the shades of color were unrivaled verses all other telescopes that I used at GSSP. I have never had a scope that has performed to this high level of performance.
Lastly, one important point that was the deciding point in having me buy a Stellarvue telescope rather than another high quality brand refractor such as Astro Physics or Takahashi, was that Vic guarantees a strehl ratio with these telescopes of .98-.99. No other manufacturer of refractor telescopes worldwide provides the customer with this guaranteed level of performance. Without this data one it just relying on the reputation of the manufacturer, and they will give you absolutely no guarantee that their telescopes will perform to any standard. I was NOT willing to take this risk. I was given a strehl printout of the telescopes performance at no additional cost.
In closing, I give this telescope my highest rating, and plan to put in an order for a 152mm soon.
