Top Rated: The SVX102T-R is the carbon Fiber tube version of our premier high-performance lightweight 4” f-7. (714mm focal length) air-spaced apo triplet refractor. This telescope has recently been reviewed by Tony Hallas in Astronomy Magazine and was also reviewed in Sky and Telescope magazine by Dennis DiCicco. Two outstanding reviews, both by recognized experts in their field.
Waiting Period: This telescope is an investment. Please do not order if you are in a hurry or you cannot tolerate unforeseen delays. Time is not of the essence, optical accuracy is. We estimate that an order placed now will be completed in about 30 - 60 days. This our best guess estimate on when a telescope ordered now should be delivered. If it takes longer to perfect some optics or something else takes place, like a batch of bad glass, additional delays can happen. One thing is certain, the sooner you order, the sooner you will receive yours.
Fully Multi-Coated Apochromatic Triplet Objective: This telescope has a 101.5mm f-7 apochromatic triplet objective with an Ohara FPL-53 center element, and provides extremely high-contrast and reflector-like color correction. The triple-tested lens comes with an interferometric test report. To further enhance the high level of contrast, extreme broadband multi-coatings are used on all six air-to-glass surfaces. These multi-coatings make the stars appear vivid and the background velvet black. The lens transmits light above and below the visual spectrum, which is important for minimizing reflections seen on CCD/CMOS images.

Focuser: The SVX102T-R now comes with an American made 3” dual speed, Feather Touch rack and pinion focuser for both visual use and imaging. This focuser comes with 2” and 1.25” compression ring adapters for visual use. The focuser draw tube adapter is threaded for the 2" adapter. When converting from visual use to imaging, unthread the 2" adapter from the knurled part at the end of the focuser and thread the field flattener or reducer flattener into its place.
Objective Lens: The 101.5mm clear aperture, 714mm focal length (f-7), air-spaced apochromatic triplet uses an Ohara FPL53 center element. Our 102 APO lenses are now .99 Strehl or higher. A test report is included with purchase.

Many experts have pointed out that the Stellarvue 102 has exceptional optics; read Dennis DiCicco's review of the SVR102T as it appeared in Sky & Telescope magazine. The Stellarvue SVX102T-R has been designed as our best dual-purpose 4” telescope for both visual and photographic use. Photographic performance with cameras is excellent with the addition of the photographic field flattener. This is among the sharpest 4” class telescopes ever offered. See the Sky & Telescope magazine review of the SVR102T. Also, see the NEAF video featuring the SVX102T.

Let me first say I'm no expert and would describe myself as a 74 year old advanced beginner amateur astronomer who has spent most of my time in the last 10 years frustrated and struggling with entry level equipment. After researching the equipment market and "Cloudy Nights" for the past year and nearly going down the Chinese rabbit hole I bought the Berlebach Uni 18 tripod, the Losmandy GM8G mount to support the Stellarvue SVX 102T-R. I bought the tripod and mount and used my modified ETX90 to get familiar with the mount while I waited for the SVX 102T-R to be manufactured, about 4 months. 2 nights ago was first light and it was like a door opened to the night sky. Using the TeleVue Delos 14mm eyepiece and the SVX everything I look at was so much more clear and detailed especially Uranus Jupiter and the Moon than I had ever seen before. Mind you Jupiter with this magnification wasn't larger but clearly was more detailed and the black background, well you'd have to see it for yourself! I went on letting the Gemini 2 take me on a tour of the Messier Catalog even though in Las Vegas my house blocks a good part of the eastern sky I have good western exposure. Beyond the obvious beauty of M45 and M31 I was struck by M37, 38 and 39 open clusters and how much there was to see and study. Moving on to Orion at 51x that was truly eye candy however I swapped out my 14mm for my 6mm orthoscopic (40 deg FOV) along with a 2x TeleVue barlow just to see what the Raptor would show me. To my surprise there was still a good amount of light and more detail than I've ever seen even though the sharpness was ever so slightly degraded. All I can say is "Quality, Quality, Quality. Having worked my entire 36 year career for a German company I've worked with quality imaging and mechanics. Stellarvue clearly has that to their credit and represents the value for the price they charge hands down. I very much like that they are not only raising the bar here for American companies but providing some light away from the flood of imported equipment. I'm grateful for the direct support I've had from Isaac and Vic Maris and the whole manufacturing staff at Stellarvue. Keep up the good work!
It has been absolute pleasure to purchase a Stellarvue scope which is my first. This will not be the last. This scope is by far the best I have ever had. I just recently used their 4.7mm 100° eyepiece and with 102mm refractor and Jupiter looked nearly as good as with my C14HD with 9mm. I think I’m converted to refractors.
I love this telescope. Images are so sharp. Built like a work of art. High strehl rating makes a difference. A handle would be nice.
This scope may well become my forever scope. The views are flawless, almost 3D at times. Build quality is second to none. It strikes an excellent balance between the SV130 I sold(you’re gonna need a bigger mount) and the SV80 I had (not enough aperture). It’s strength is lunar and planetary, but it’s no slouch for the brighter deep sky objects. I really like the focuser. I’ve owned 3 scopes with FT focuser prior. I agree that the FT has the edge, but the SV focuser exudes quality as well. This scope gets my highest recommendation.
I put together an SVR102T, D1035 correct image erecting prism, and a Denkmeier Binotron 27 specifically for wildlife observation, and with the SFF7-25 field flattener for photography. It far exceeded expectations in all regards. There is no comparison with conventional spotting scopes, even the most expensive, and it was far brighter and contrasty than a Questar 3.5 Duplex. On a crisp morning, the black pupils of a wolf's eye (at Yellowstone) were clearly resolved against the dark brown of her irises, a third of a mile away (terrestrial analog to splitting binaries). Add the faint sound of her howl as she throws her head back, and you're right there. Thanks, Stellarvue!
I had owned one of Stellarvue's original doublet apos, the f/8.7 SV-102A. It was (and is) a great scope. But in the interest of upgrading from a doublet to a triplet, for visual observation and eventual astrophotography, I purchased the SVR-102T. The lower weight, lower OTA thermal expansion/contraction and raw beauty of the carbon fiber tube were admittedly also factors in this purchase. I purchased the SVR-102T scope variant with the FeatherTouch 2.5" rack and pinion focuser. It's hard to break the FeatherTouch habit, having used one all these years, albeit the reverse Crayford variety. Plus the focuser rotation feature is advantageous for my numerous club outreach functions, for those height-challenged folks who must otherwise strain to get to the eyepiece and that would otherwise involve loosening and retightening screws that hold the diagonal - an invitation for a potential bad outcome. So the views are, of course, most impressive. But the happy epilog to this story is that I sold my original SV-102A apo to a fellow club member who was invited to the White House (yes, that one) to an astronomy outreach event held by the President - not a bad outcome for a seasoned veteran SV apo scope!
In the past month or so I ordered I ordered and received the SV102mm Apo with Stellarvue focuser, the SV60mm Apo with Stellarvue focuser, and the aluminum surveyors tripod with M2 mount and MEC2 column. When I opened the boxes the quality and finish of everything was first class. And yes, the first thing I said was, "Wow!" Thanks to the weather here in SW Montana I haven't looked at the sky but I've used them for terrestrial viewing and I sure don't have anything to complain about. Quite the opposite. Excellent choice
I have only had a few outings with this telescope, but I can say this is hands down the finest refractor I have ever used. Pinpoint stars that give a 3D effect when used visually. And a mechanical fit and finish that is exquisite.
Thank you Vic and company for producing such quality instruments here in this country.
Beautifully made telescope, ultra smooth and robust focuser, and the views are very sharp with excellent contrast and color. Highly recommended!
