Product Description
This is the latest version of our 130 mm apo triplet refractor. This model uses a unique lens design that provides excellent sphero-chromatic correction using a premier super low-dispersion center element and a very expensive Lanthanum rear element. Each telescope comes with:
- CNC mounting rings
- Your choice of three different 3 1/2" focusers
- a retracting dew shield
- metal dust cap
- Thickly padded case
Optics
Our SVX 130T apochromatic telescopes use objectives that have the highest optical ratings as measured and documented on our Zygo Phase-Shifting Laser Interferometer. Our 130 mm SVX series optics are rated at .99 - .996 Strehl with excellent optical correction of aberrations commonly seen in mass-produced optics. To attain this level of optical accuracy we must go beyond machine polishing. Our experienced opticians use specially made tools to hand-figure objectives here in our optical shop in Auburn, CA. Stellarvue Premier (SVX) Series refractors are for the astronomer who recognizes the best when they see it. Each 130T refractor comes with a Zygo interferometric test report taken in our shop, documenting the accuracy of your individual objective.
Each lens focuses light precisely, and the extreme broadband coatings on each surface enhance it even further. The stars appear vivid and the background, velvet black. Since these coatings transmit more than 99% in the visual spectrum and far above and below it, reflections seen on CCD images are eliminated.
Lenses
The air-spaced lenses 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, 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 mm refractors use simple aluminum cells which expand and contract around the glass, 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.
Focuser Options
Each 130T comes with a 3 1/2" focuser. Select one of the following:
- Stellarvue 3.5
- Feathertouch 3.5
- MoonLite NightCrawler
Cases
The Stellarvue C130L case comes standard with the SVX130T. This is our largest heavy duty soft case. It is made of the same rugged material construction as our other thickly-padded travel cases. Exterior dimensions are 39" x 10 1/2" x 10 1/2"; interior dimensions are 36" x 8" x 8". The case has two internal dividers that are held in place by Velcro and can be easily removed and rearranged.
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 F050W2 finder scope. The proper ring system for this finder is the R050DA ring system.
Diagonal: Available separately. Please note: You can purchase our best 2" diagonal above and save $50.
Eyepieces: Available separately. We recommend a complete set of the Stellarvue Optimus eyepieces for this telescope. Save an additional $159 on the star diagonal and eyepieces when you select "
Mounts: For strictly visual use, the M002CS is a basic alt-azimuth mount that will hold the SVX130T with stability.
For imaging we recommend:
Losmandy GM8-11G - A good portable tripod/mount
Losmandy G11 - Offers the best stability
Paramount MYT - A great choice for accurate long-exposure imaging
Imaging Accessories
A field flattener or reducer/flattener turns your SVX130T 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! Save $200 when you buy this flattener with the telescope; just select this option above.
Focal Reducer/Field Flattener: Shoot at 680 mm focal length f-5.25. Use the SFFRR.72-130-48. This reducer/flattener produces an image circle over 40 mm in diameter. Save $200 when you buy this flattener with the telescope; just select this option above.
Save a total of $400 when you purchase both photographic flatteners with your telescope! We will align both with your telescope prior to shipping.

SVX130T
I'll provide a more detailed review after my first use. However, the telescope arrived in perfect condition. It was securely packed with no visible damage to the box indicating it was well handled during shipping. As promised, the Strehl report was included and came in at an impressive .997! The only minor issue is the small ring adaptor for my ATIK 16200; The threads bind with increasing resistance when attempting to screw it onto both the large field flattener or the focal reducer/flattener. This occurs on the M48 female thread of the ring. My M48 Canon adaptor screws on smoothly without any resistance. Customer support has been excellent and I'm just waiting thru the weekend on a response to the adaptor ring issue. The Scope and it's accessories are truly a work of art. I look forward to getting out in the field this week for first light.

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.
