Product Description
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.
- A Stellarvue 3" dual speed focuser with 4.4 inches of drawtube travel, 2" and 1 1/4" compression ring adapters
- FB finder scope dovetail mounting base.
- Large removable extensions between the focuser and telescope for wide field bino-viewing without the need for optical adapters.
- Cnc machined, heavy duty mounting rings.
- Your choice between the Losmandy style TP013A or the Vixen-Style TP012 mounting rail.
- Handle: The Stellarvue #HAN-2 handle is included.
- Precision adjustment mechanisms on both the objective lens cell and the focuser. The telescope leaves here permanently aligned but customers requested the ability to be able to precisely adjust the focuser and the objective just in case they accidently drop the instrument on a hard surface.
Tube and dew shield: The Stellarvue SVX127D comes with an aluminum tube and dew shield that is finished in Instrument White. Fittings are black anodized aluminum. The dew shield retracts reducing the length of the telescope when being stored. Extending the dew-shield minimizes dewing of the objective at night and serves as a glare shade during the daytime.
Internal tube treatment: The inside of the main tube assembly is painted "ultra flat black" and is baffled to eliminate tube wall reflections.
Aluminum hinged rings: The SVX127D comes with Stellarvue rings that are cnc machined from one inch thick 6061-T6 aluminum. There are five 1/4-20 threaded holes top and bottom. There is a center hole, two holes that are 1.5" apart and two holes that are 2.4" apart. American made Stellarvue rings are significantly stronger than cast aluminum rings.
Light gathering and magnification power: A 127 mm refractor gathers 329 times the amount of light the naked eye does. Although Dawes limit states maximum power for telescopes under good conditions is about 300 power for a telescope of this size, since this is a high Strehl apo refractor you can exceed this power on steady nights. Check the Recommended Accessories section to make the best choice for eyepieces.
Two-year warranty and Stellarvue Service: We are friends for life. Stellarvue telescopes and accessories are covered by a two-year warranty. But it does not stop there. Since we are a telescope maker, we can repair your telescope for a very nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue Telescope with confidence. Our customer care is legendary.
Optional Accessories
In addition to the supplied accessories, you will need the following:
1. Visual Use: For visual use you will need a star diagonal and eyepiece(s). Our finest visual accessories may be purchased with the telescope at a discount when the telescope is finished (see special offers below).
2. Mount and Tripod: We recommend the following mount/tripod combinations for this telescope:
- Celestron AVX Mount/Tripod. This is a lightweight mount with a go-to computer. It is a very reasonably priced and portable EQ mount.
- Losmandy GM811G. Made in the USA, this is a precision EQ mount with computerized go-to function. If you plan to image with this telescope this is a good choice. If you only want to use the telescope visually, the less expensive GM8 version will work fine.
3. Astrophotography: To image with this telescope, you will need a photographic field flattener (SFFX-1 for SVX127D). Imaging the night sky will also require an accurately guiding mount, off-axis guider, or a guide scope with a guiding camera.
4. Finder Scope: For easily locating objects at night, we recommend our top rated 50 mm optical finder scope. To mount the finder scope, you will need our R050DA adjustable mounting rings. Our EI002 reticle illuminator will allow you to see the crosshair reticle in the eyepiece at night.
5. Optional C130SKB Hard Case. This American-made, waterproof hard case comes with a very durable die cut foam lining.
Specifications:
Objective Lens:
127 mm clear aperture, 1,016 mm focal length (F-8), apochromatic doublet using super low dispersion (SD) optical glass and Lanthanum.
Tube Assembly:
Machined, fully baffled, aluminum tube painted Instrument White outside, ultra flat back inside.
Weight:
Telescope tube weighs about 16.6 pounds. Weight with mounting rings:19.4 pounds.
Dimensions:
The main tube has a 5-1/4" diameter. The complete telescope is about 35 3/8” long with dew shield retracted and about 41 3/4" when extended. This is with the 60 mm bino-viewer extension attached. When this extension is removed, and bino-viewers are used the telescope itself is 60mm shorter. The extension is 120 mm on the 3" Feather Touch version since this focuser has a shorter drawtube.
Dew shield:
6-1/2" diameter fully retracting dew shield with cap.
Focuser:
This telescope comes standard with a Stellarvue 3" dual speed focuser. This focuser is great for visual use and imaging. You can also upgrade to the Feather Touch 3" focuser. Both of these focusers come with 2" and 1.25" compression ring adapters and a finder scope mounting base is included. The Stellarvue 3" focuser weighs 3.12 lbs and the 3" Feather Touch focuser weighs 4 lbs.
Extensions to facilitate virtually any binoviewer:
The standard model with our outstanding 3" focuser comes with two large extension tubes placed in between the focuser and the main tube. One is 60 mm long and the other 40 mm long. The extensions stay in place when used with eyepieces or a photographic field flattener but when binoviewers are added along with the 2"-star diagonal, one or both extensions can be removed. This positions the focuser closer to the objective eliminating the need for additional optical correctors to enable the binoviewer to come to focus. This increases the size of the field while reducing the amount of glass between the objective and the eyepiece. This results in a brighter, wider field of view. If ordered with the Feather Touch focuser, two 60 mm extensions are provided since that focuser has a shorter drawtube.
Rings: R130 cnc machine mounting ring set with five 1/4-20 threaded holes top and bottom. Holes are spaced 1.5” and 60 mm apart respectively, with one in the center. These are not lightweight, cast aluminum but machined 6061-T6 aluminum that is far more durable than castings.
Light Gain: 330. (Human eye = 1)
Manual: A full-color, printed operator's manual is included with each telescope. Here is a PDF copy of that manual: SVX127D Manual

SVX127D
If you’re looking for a USA made high quality refractor from a company that provides a superior product and superior service from people who care about you having a fantastic experience with your purchase look no further than Stellarvue. The SVX127D that I received is beautifully crafted and looks great on my Losmandy GM811. It will be a great hit at public star star events where the bulk of telescopes are SCT’s and reflectors. Thanks for a great experience everyone at Stellarvue

SVX127D
There is outstanding optical quality and service from Stellarvue. I am very impressed with this telescope. The finest workmanship is evident in all aspects. Optically I can't image any better for 127mm.

SVX127D
Vic offered me this scope at a discount because the tube had a blemish. For the life of me, I can't find any flaw. It's beautiful. The packing was wonderful. The first time I had it out was at a mini public viewing on the 10th tee at the Duke Univ golf course in Durham, NC. Not a dark sky at all, but the Washington Hotel gives the club a gratuity for being there. Looking at Saturn, I commented to the other two guys, who were both using Schmidts (an 8' and a 10"), that the seeing had improved markedly and they both agreed. Looking through each of them, their images were soft (to me) and they thought they had pretty good views. There was no comparison with what I had. Thanks, Vic. My only gripe, and it's a very small one, is I wish the carry handle had a finder bracket built in like the Wiliam Optics handle does. The SKB case with the upgraded foam was worth the additional expense. The scope nestles firmly in its place. I'm pleased with my entire experience buying through Stellarvue.

An incredible telescope
I am very pleased with this telescope. It is very solidly built and provides tack sharp lunar images (which I use the telescope for the most). I am mostly a visual observer, but the SVX127D works great for taking sharp lunar images. The SVX127D is highly recommended. Thanks SV.

SVX 127D
Received an SVX 127D this week. Unboxed telescope and accessories that purchased at the same time. I found the telescope in good order after shippment, shipment also arrived sooner than I expected. Carefully examined telescope for fit and finish I found the scope to be flawless and focuser very smooth. Awaiting several accessories before using the scope on the night sky. I'm glad I found Stellarvue and such a high-quality telescope. With some parts made in the US and a lens that was figured in states also. A rare find these days.

Review 7 on Scope No. 007
After owning a APM 140, and then going to an 8” Edge, I wanted a refractor again and was considering a 130 triplet, then Stellarvue announced they were going to produce 5” doublets. It arrived in the heavy duty case that was double boxed with a huge air gap all the way round. The packaging protected the scope - travelling across the pacific to NZ. I ordered it with the feather touch focuser because I always wanted to at least have one on a scope. It is lighter in action, than the 3.7 R&P focusers I was used to but it never slips. I cannot think of any flaws this scope has. The tube is solid, the extension piece which is removable for binoing, was machined so well and aligned accurately with a fine thread, that when I wanted to remove it, I found it hard to see where it came apart. I don’t suffer much from cool down time, as the scope is in an insulated shed and outside is usually 2-3 degrees C different, I am 99% visual. I had the 127D at the same time I had the 8” Edge, and comparing them against each other, stars looked better in the refractor due to contrast, and looking at nebula, I don’t think I was loosing much in performance. My sky is generally not able to put out what the 127D can do, as I hardly ever have perfect seeing and always a lot of moisture in the air. The scope will always put out the best it can - on any given night. So you never have to doubt the scope is performing….….if the view is not great its the sky thats the issue. This scope is a keeper.

SVX127D
I am extremely pleased with the optical quality of this scope. Also, the mechanical build of the OTA is top notch. The Stellarvue focuser is a solid performer. The 5” aperture puts up beautiful views of the planets. Definitely 5 stars. Thank you SV

Stellarvue Doublet Apo SVX127D
The telescope arrived months earlier than projected. I am still waiting for the weather to clear so it has not seen "first light" yet. It appears to be very well made.
