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. The 90mm and the 102mm telescopes are our most popular since they are relatively light and portable. The 90mm is airline carry-on size and the 102 can be made airline carry-on size by unthreading the focuser.
We now show the 102mm on sale if you order it with the smaller 2.5" focuser. This smaller focuser has been requested by those who only use it visually. For imagers we recommend the 3" focuser which sell for the standard price.
Waiting Period: We estimate that an order placed now will be completed in about one week. This our best guess estimate on when a telescope should be delivered. If it takes longer to perfect some optics or something else takes place, 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. Glass is ground and polished to meet our prescription. Once this is accomplished, we utilize our Zygo Phase Shifting Laser Interferometer and a Double Pass Autocollimator to carefully and meticulously hand figure each objective. This is done to eliminate common issues we find in machine polished objectives including astigmatism, coma, and spherical error. We also address trefoil by replacing any elements that exhibit this aberration during the process. SVX optics are more accurate than our former SV models. Each SVX series refractor comes with a Zygo interferometric test report taken in our shop in red light, documenting the accuracy of the objective. To see part of this process in action, watch our YouTube video.

Focuser: The SVX102T-R comes with a Stellarvue 3” dual speed, 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. 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.

Every now and then the world sees a new refractor series from multiple companies across the world that advertise on their features as being sharp, contrasty, and made with fancy ED glass (which usually contains fluorite). The market is full of similar looking tubes, sometimes from the same manufacture oversees, but with a different logo. This is not what this refractor is. If ever there was an era of ultra compact “super planetary” refractors, this is it. We all know a 4” class APO triplet design loses on detail and resolution compared to a 6” or 7” refractor. I would not have believed that pushing the theoretical Strehl envelope this far would land this refractor as a heavy hitter. But believe me it does. This is a case where words alone cannot convey or impress upon the optical performance of this refractor. You have to use it to believe it—you have to see for yourself. A portable refracting telescope that takes on the appearance of art, but delivers a view that one can only try to convey. When your friends and family tell you that they see the red spot of Jupiter as looking like rust/vivid red, or the dark dust lanes in Andromeda so clearly, and the six stars of the Trapezium… especially with inexperienced observers—that’s the mark of a marvel of engineering and care taken to design the perfect lens. I still use a 6” APO frequently, but this 4” “travel scope” as I intended it for, I always set up now. The unusually high Strehl number I think might change lucky imaging as well. I’m thinking this is now a goal I will pursue with this refractor. I like Astro-Physics products, and I’ve been watching the growth of Stellarvue for a while. Vic and his team clearly know what they are doing, and I know with every improvement and new goal of optical precision—comes the next advancement and pioneering of literally the next generation of refractor design. No compromise, no cut corner. Stellarvue, Astro-Physics, and Takahashi I think are the best telescope makers for 3”-6” refractors, despite what people may say about optics and the technicality of lens making and aberration orders, very few individuals know how to properly design a lens element and complete lens cell system. Most people reading this probably have scopes from all the telescope makers I just mentioned, or may be new to the world of refractors. Either way, this refractor is not just a keeper for me, but is something that I love to share. It is something that is meant to be shared, and I think it sits at the perfect balance being f/7 at 102mm aperture. Lastly, as with many fast APO triplets field curvature is something that you will have to correct depending on your eyepiece design. Some of my low power eyepieces have no trouble at all, some TeleVue eyepieces struggle a bit. This however applies to low powers only, and I have found that using a visual/photographic field flattener eliminates the field curvature effect. Also, every time I pull this refractor out of the bag, somehow I get some AP traveler vibes. What a terrific instrument. Happy observing/imaging to you all, and I do hope that those who decide to buy this refractor or the bigger 5” version get some spectacular seeing and views as I have.
This is absolutely the finest telescope that I have ever owned. It is flawless!
The Stellarvue SVX102 Raptor is a wonderful instrument. The only think I found better than the Telescope in the service Vic and his team provides. 1st class all the way
Fantastic scope. Beautifully assembled, superb optics. Exactly the high quality I was looking for.
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!
