## Summary description

Tele Vue Ethos-SX 4.7mm eyepiece is a wide-field astronomical eyepiece designed for 2" and 1.25" focusers. With a 4.7 mm focal length it provides high magnification for planetary and deep-sky observation. The eyepiece offers a wide apparent field of view for improved framing, comfortable viewing and precise detail resolution for serious amateur astronomers.

## Long description

The Tele Vue Ethos-SX 4.7mm 2"/1.25" wide-field eyepiece is a high-magnification astronomical eyepiece intended for use with 2" and 1.25" focusers. With a 4.7 mm focal length and a wide apparent field of view, it delivers a compact exit pupil and increased image scale for detailed planetary views and higher-resolution examination of small deep-sky objects. The eyepiece is engineered for serious amateur astronomers seeking precise optical performance, comfortable eye placement, and minimal distortion across the field.
Advantages
The eyepiece combines a short focal length with a wide apparent field of view to provide high magnification while preserving a roomy, immersive view. Optimized optical design reduces edge aberrations and maintains contrast, enabling clearer detail on planets, double stars, and compact nebulae. Compatibility with both 2" and 1.25" focusers offers flexibility across different telescopes and mounting setups, and the robust mechanical construction ensures stable alignment and repeatable performance during observing sessions.
Suitable for
High-magnification planetary observation (Mars, Jupiter, Saturn)
Detailed study of double stars and lunar features
Viewing small or compact deep-sky objects where higher image scale is required
Observers who use telescopes with 2" or 1.25" focusers and want a versatile eyepiece
When it may not be suitable
This eyepiece’s short focal length produces a small exit pupil and high magnification, which may limit performance under poor seeing conditions or with small-aperture telescopes where image brightness and seeing stability are more important than magnification. It is less suitable as a wide low-power eyepiece for large extended deep-sky objects where a larger true field of view and brighter image are preferred.
Key specifications
Focal length: 4.7 mm
Mount compatibility: 2" and 1.25" focusers
Optical type: wide-field eyepiece with a large apparent field of view
Intended use: high-magnification planetary and detailed deep-sky observation
Mechanical features: precision barrel and eye relief suitable for eyeglass wearers depending on individual fit
How to use
Install the eyepiece into a compatible 2" or 1.25" focuser and secure it with the focuser’s thumbscrews or adapter. Start observing at lower magnification to locate the target, then switch to the 4.7 mm eyepiece for detailed inspection. Allow the telescope to reach thermal equilibrium and use careful focusing to optimize sharpness. For planetary work, reduce stray light and use appropriate filters or a diagonal as needed. Adjust eye position to locate the exit pupil and minimize vignetting for the most comfortable view.
What to consider before purchase
Compatibility with your telescope’s focuser size (2" or 1.25") and available adapters
Typical seeing conditions at your observing site—high magnification performs best under steady seeing
Whether your telescope aperture supports useful image brightness at this magnification
Comfort with short eye relief and potential need for a Barlow or different eyepiece for lower magnifications
Usage recommendations
Use this eyepiece for targeted, high-resolution observing sessions: allow the telescope to cool, use precise focusing, and pair it with stable mounts and appropriate filters for the best planetary and small deep-sky results.
