Product Description
The SVX102T is the aluminum 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.

Specifications:
Focuser: The SVX102T now comes with our dual speed, rack and pinion, 3” Stellarvue SV focuser, or for an additional $500 you can upgrade to the premium 3" Feather Touch rack and pinion focuser for both visual use and astrophotography. Both focusers comes with 2” and 1.25” compression ring adapters for visual use, and the focuser draw tube includes an adapter with a 2" compression ring. When converting from visual use to imaging, unthread the 2" compression ring 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.

SVX102T
I finally made the plunge on a "forever scope" and couldn't be happier. The scope is built like a tank, and the Stellarvue focuser has been rock solid. My first light was several weeks after receipt of the scope, due to weather, and it was worth the wait. The data I was able to capture was very easy to process, with background gradient being very smooth, and noise reduction was very easy, despite a smaller than usual amount of data. So far I am extremely pleased with this scope. The sales staff at Stellarvue was outstanding. I received my scope actually under the estimated time for shipment. Thank you very much Stellarvue!!

SVX102T
The 102 triplet lives up to its advanced billing. A beautiful instrument with no flaws I can detect. I have used it visually, and it performs very well. But my main use is in astrophotography and it really shines in that area. With the SFFR.74 reducer, the telescope becomes an f/5.2, 518 mm astrograph. Sharpness and field flatness are very good edge to edge. This is not an inexpensive instrument, but it is great value for the money.

SVX102T
Tonight I had first light with my new SVX102T. I intentionally picked a cold night (23 F) to try to provoke pinched optics. The Star Test was picture perfect, no evidence of pinched optics, astigmatism, or false color in the diffraction rings inside or outside of focus. Based on the Star Test, this scope appears to be very well corrected. I am fortunate enough to own three Astro-Physics triplets (92, 130, and 140 mm) and the Star Test of the SVX102T was indistinguishable from my AP scopes. That is the highest possible compliment for the SVX102T. As expected, the mechanics of the FT focuser were excellent. There is no “slop” when sliding the dew shield. Even the telescope rings are well-machined.

Superb Telescope
I’ve looked through many telescopes in the last 20 years. From SCT’s, Dob’s, MCT’s and refractors. This scope has not only provided stunning views, but exceeded my expectations in every aspect.

SVX102T
I've wanted a good 4" refractor to add to my collection of scopes for years. (Earlier this year, I tried a Sky-Watcher Esprit 100, but wasn't happy with the uneven star spikes around bright stars.) Since there were so many positive reviews for Stellarvue scopes and I was impressed with their quality control process, I decided they would be a better bet. This is the first image from my newly arrived Stellarvue SVX102T. I'm pleased to report this scope produced great results out of the box. The overall image sharpness and star field quality exceeds expectations. The SFFR.74 reducer produces better stars at the corners than any field flattener/reducer I own. This is especially important for larger APS-C or full frame sensors. The stock focuser is rock solid, with no slippage or sag that I can detect. While Stellarvue offers a Feather Touch focuser as an upgrade option, I don't feel the need for one in my case. The overall build quality and finish is excellent. Stellarvue includes a highly detailed optical test report for each scope, which indicates their pride in craftsmanship. (The Strehl ratio for my scope is 0.993!) This is not your average mass produced scope!
Two thumbs up for the Stellarvue SVX102T! I highly recommend it. -
Highly Recommend
I am very happy with my purchase of this telescope. I have owned multiple telescopes over the years, SCT, Newtonians, and Refractors, but this one is truly special. While I primarily use it for imaging, its visual views were surprising. There was no color fringing, and when focus was reached stars were pin points. M13 looked like a round box of the smallest diamond chips you can imagine. The build quality of this scope is markedly better than all others I have seen, and most do a good job, but this one is better. Everything fits together superbly, and anything designed to move is buttery smooth. The mounting rings are high quality and well designed for holding the scope with good separation and for adding stuff to the top. Vic and his team were great to work with. Vic helped me pick various options for the scope itself, including accessories, and in some cases talked me out of spending additional money when it did not make sense. I highly suggest buying both the flattener and reducer at the same time, as they will build them to match your scope optically. You can’t beat that. While 4 inches is not a light bucket, it is a great size and focal length to do the imaging I want to do, since it will still do pretty wide fields for most objects. That said, this size scope will still do justice to many galaxies. Super high quality, built in the USA, and great customer service. You can’t go wrong with this one.

Stellar Views!
My first views thru the SV102 were simply breathtaking! My view of the Orion Nebula never looked better. Sharp, images with great contrast. This telescope is solidly built. I can’t think of a single thing they could improve upon! This is my first Stellarvue scope, and it won’t be my last!

Value Plus
Rock solid. When you put your hands on this scope you know it was built to last and outperform all the other scopes on the market. Very helpful staff.
