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 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 simply unthreading the focuser.
Save $100 if you order now. The telescope comes standard with our highly rated Stellarvue F-SV3B 3" dual speed focuser with 2" and 1.25" adapters. This size focuser minimizes vignetting. Our 3" Stellarvue focuser is extremely popular, 90% of the orders we receive for this telescope specify this focuser as it is smooth and stable. It makes a great imaging focuser and works well with either the Optec or the ZWO EAF focus motors.
Available now: Stellarvue SVX102T Refractors are now available when ordered with the standard Stellarvue 3" focuser. There is a waiting period for those ordered with Feather Touch and Moonlite focusers since these focusers are currently backordered.
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. We finalize our optical figuring by centering the correction in green light. To see part of this process in action, watch our YouTube video.
This is our most popular telescope and sales have doubled over the past year following the introduction of cheaper, mass produced telescopes that look pretty but have noticeable optical defects. Our customers buy this telescope with confidence in the optics and our personal support after the sale.
SVX Optics
Specifications:
Focuser: The SVX102T comes with a choice of four different focusers: The Stellarvue 2.5" dual-speed visual focuser, the 3" Stellarvue photo & visual focuser, a 3" Feather Touch focuser or a 3" Moonite Computerized focuser for remote imaging. All focusers come with 2” and 1.25” compression ring adapters for visual use. 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.
Light Gain: 213x (human eye = 1)
Image Circle:
- with 3" Focuser and SFFX-1: 43 mm

Weight: Telescope tube weighs 9.8 lbs. with 2” adapter and 1 1/4" adapter. Rings weight .8 pounds each.
Case: Included 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 cnc machined 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.
Recommended Accessories:
Finder: Optional. We carry the F002 multi-reticle finder or our own top-rated optical finders.
Mounting Plate or rail: Optional. We recommend the TP010 rail for telescope mounts using the Vixen style rail, or the optional TP009 or TP013A rail for mounts that use the larger Losmandy-style rail.
Star Diagonal: Optional. Please note: You can purchase our 2" quartz dielectric diagonal upgrade for only $199 by selecting the option above. The upgrade diagonal is the same as the D1040Q deluxe dielectric diagonal but does not come with a 1.25" adapter as the telescope already has one.
Photographic Field Flattener: Optional. We recommend the SFFX-1. Select the one for the SVX102T. Converts your telescope into a 714mm f-7 astrograph/telephoto.
Photographic Reducer/Flattener: Optional. We recommend the SFFR.74-102T. Converts your telescope into a 535mm f-5.25 astrograph/telephoto.

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.
