Product Description
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: We are in continual production and waiting periods for 102mm telescopes are about 30 days. Call us for a more precise estimate.
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. These SVX series optics are rated at .99 Strehl and optimized in red light. By bringing our optical figuring in-house, we reduced errors and improved the optical quality over our former SV telescopes. Our experienced opticians use specially-made tools to hand-figure objectives here in our optical shop in Auburn, CA. To see part of this process in action, watch our YouTube video. Each SVX refractor comes with a color Zygo interferometric test report taken at full aperture in our shop, documenting the accuracy of your completed objective.

Specifications:
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.
Light Gain: 213x (human eye = 1)
Image Circle:
- with 3" Focuser and SFFX-1: 43mm
- with 3" Focuser and .74X Reducer/Flattener: 40mm
Tube Assembly: Lightweight fully-baffled carbon fiber tube and dew shield. Painted ultra flat black inside. 105mm diameter main tube. To compare the differences between an aluminum tube and carbon fiber tube, visit our Aluminum vs. Carbon Fiber comparison page.
Dew Shield: 4-3/4” diameter, 8-5/16” long retracting aluminum dew shield with cap.
Dimensions: OTA: 18.25” long in travel mode (focuser unthreaded), or 18.75" if using our large plastic cap to cover the end. 22.5” long with focuser in place and dew shield retracted; 28” with dew shield extended.
Weight: 9.6 lbs with 2” adapter and 1 1/4" adapter. Rings weigh .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 F001 red dot finder and the F002 multi-reticle finder.
Mounting Plate or rail: Optional. We recommend the TP010 rail for telescope mounts using the Vixen style rail, or the optional TP009 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 below. 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.

Additional Information
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.

Trading Up
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!

Redlining the Wow! factor
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

Phenomenal instrument!
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. -
Excellent fit, finish, and tack sharp views
Beautifully made telescope, ultra smooth and robust focuser, and the views are very sharp with excellent contrast and color. Highly recommended!
