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. Also, check out the Dark Rangers Inc. video analyzing this scope and its performance here. The SVX102T is our most popular telescope since it is relatively light and portable. The102T can be made airline carry-on size by simply unthreading the focuser.
The telescope comes standard with a Stellarvue F-SV3B 3" dual-speed, fully-rotating focuser with 2" and 1.25" adapters. This size focuser minimizes vignetting. Our 3" Stellarvue focuser is 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, Prima-Luce or ZWO EAF focus motors. This telescope may also be upgraded to a 3" Feather Touch or MoonLite NiteCrawler focuser by selecting the options above.
Availability: We begin the production of all SVX objectives one year ahead of time so while it takes up to a year to perfect each objective, we usually have several lenses available when you order. This means we can generally deliver this telescope within one or two weeks depending on the availability of focusers. Call us for more specific information on delivery time estimates for the telescope and focuser you are looking for. (530) 823-7796.
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.
Optics: SVX102T is rated at .97 Strehl or higher as measured on our Zygo Phase Shifting Interferometer in red light. Once the aberrations are minimized, we move the center of correction toward the middle of the visual spectrum. Visit our SVX Optics Page to learn more about this process.
This is our most popular telescope, and sales have doubled thanks to the high-quality images that have been taken by so many through the years. These optics are meticulously hand figured in our shop to minimize aberrations. Our customers buy this telescope with confidence in both the optics and our level of personal support after the sale.

Specifications:
Focuser: The SVX102T comes with a choice of three different focusers: The Stellarvue 3" Stellarvue photo & visual focuser, a 3" Feather Touch focuser or a 3" Moonlite 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. The Stellarvue 3" focuser weighs 3.12 lbs., the Feather Touch 3" focuser weighs 4 lbs. and the 3" Moonlight Nitecrawler (WR30) weighs 7 lbs.
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: 41 mm
- with 3" Focuser and .75X Reducer/Flattener: About 40 mm

Recommended Accessories:
Optional American-made waterproof hard case: The telescope can be shipped with or without a case. Our current case option is an American-made SKB 3i-2615-10BE waterproof hard case with custom American made Polyethylene padded interior. The Polyethylene interior is superior to polyurethane which absorbs moisture like a sponge. This is the 102 case with the vibration-absorbent padding custom cut to accomdate the telescope with or without focus motors installed. The case accepts the complete telescope with rings, rail, handle and focus motor attached. Two circular openings in the case will hold the SFFX-1 field flattener and the SFFR.74 reducer/flattener.
