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.
Fully Multi-Coated Apochromatic Triplet Objective:
Using a 101.5mm f-7 apochromatic triplet objective with an Ohara FPL-53 center element, this telescope provides extremely high-contrast and reflector-like color correction. This triple-tested lens comes with an interferometric report. To further enhance this high level of contrast, extreme broadband multi-coatings are used on all six air-to-glass surfaces. This boosts contrast, making the stars appear vivid and the background velvet black. These coatings transmit light above and below the visual spectrum, which minimizes reflections seen on CCD/CMOS images.

WEIGHT
9.8 lbs with 2” adapter and 1 1/4" adapter. Rings weigh .8 pounds each.
C009S HEAVY DUTY TRAVEL CASEIncluded with the telescope purchase is a heavy-duty, nylon, reinforced refractor case for 102mm - 115mm telescopes. Outside dimensions: 32” X 9 1/2” X 9 1/2”. Inside dimensions: 29 3/4” X 6 1/2” X 6 1/2”.
RINGS:
Included with the telescope purchase is Stellarvue's American-made ring set with five 1/4"-20 threaded holes on top and bottom. Holes are spaced 1.5” and 60mm apart respectively, with one in the center. Ring sets are made on Haas CNC machines.
FINDER
Optional. We carry various finder scopes to help locate objects more easily. We highly recommend our 50mm correct image optical finder.
PLATE/RAIL
Optional. We recommend the TP-10 rail for telescope mounts using the Vixen style rail or use the optional TP6 for mounts that use the larger Losmandy style rail.
DIAGONAL
Optional. Please note, you can purchase our 2" quartz dielectric diagonal upgrade for only $199 below. The upgrade diagonal is the same as the D1040Q deluxe dielectric diagonal but it does not come with a 1.25" adapter since the telescope already has one.
PHOTOGRAPHIC FIELD FLATTENER
Optional. We recommend the SFFX-1. Converts your telescope into a 714mm f-7 astrograph/telephoto.
PHOTOGRAPHIC REDUCER/FIELD FLATTENER
Optional. We recommend the SFFR.74-102T.

Additional Information
Many experts have pointed out that the Stellarvue SVX102T has exceptional optics. Read Dennis DiCicco's review of the SVR102T as it appeared in Sky & Telescope magazine. While this review covers the carbon fiber version of this telescope, they are virtually identical telescopes with the same lens, rings, and focuser. The only difference is the material of the tube and dew shield.

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. -

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.
