- SVX127D Manual
Optics: SVX127D is rated at .97 Strehl or higher, as measured on our Zygo Phase-Shifting Interferometer in red light. Visit our SVX Optics Page to learn more about this process.
Light gathering and magnification power: A 127 mm refractor gathers 329 times more light than the naked eye. While Dawes limit states maximum power for telescopes under good conditions is about 300 power for a telescope of this size, you can exceed this power on steady nights because this is a high-Strehl apo refractor. Check the Recommended Accessories section to make the best choice for eyepieces.
Additional Accessories
In addition to the supplied accessories, you will need the following:
1. Visual Use
Visual accessories may be purchased with the telescope at a discount when the telescope is finished (see special offers below).
2. Mount and Tripod:
- 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:
- photographic field flattener (SFFX-1 for SVX127D)
- guiding mount, off-axis guider, or a guide scope with a guiding camera.
4. Finder Scope:
- 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 and fully baffled aluminum tube, painted Instrument White outside, Ultra-Flat Black 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 60 mm 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 the Stellarvue 3" dual speed focuser with 1.25" and 2" adapters and two finder scope mounting bases. Alternatively, you can select the Feather Touch 3" focuser. It also comes with a 2" and 1.25" compression ring adapter and a finder scope mounting base.
The Stellarvue 3" focuser weighs 3.12 lbs., and the Feather Touch 3" focuser weighs 4 lbs.
Extensions to facilitate virtually any binoviewer: The standard model 3" focuser comes with one 60-mm long extension tube and 40-mm long extension tube. 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 allow the telescope 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
BUY ACCESSORIES YOU WILL NEED AND SAVE!
Star Diagonal: You will need a star diagonal for visual use. Get our 2" Quartz star diagonal with twist-lock eyepiece holder for $50 off. We provide these with the telescope at a discount to ensure that you get our best star diagonal. Select the D1040QU star diagonal above to add it to the telescope. Since the telescope already comes with a 1.25" adapter, the upgrade diagonal does not include one. Learn more about this star diagonal on our D1040Q Page.
Eyepieces: We offer two selections of eyepiece sets with this telescope. Select either the eyepiece set or the eyepiece set with the Quartz Dielectric diagonal and save $100 when you upgrade at the time of purchase.
Mount and Tripod: You will need a mount and tripod for your telescope. When you add ether of the optional munts you will save $100. Learn more about the Celestron mount on the AVX Page. Learn more about the American-made Losmandy mount on the GM811G Page.
