Eyepiece Vixen SLV 4mm 50° 1.25

Vixen SLV 4mm eyepiece 50° 1.25″

If you are looking for an eyepiece that reveals every planetary detail without compromise, the Vixen SLV series is exactly what you need. These eyepieces have earned an outstanding reputation among astronomers worldwide and are widely regarded as one of the best planetary eyepieces on the market. The SLV 4mm model offers high magnification with an exceptionally clean and contrasty image - an ideal choice for observing the Moon, the planets of our solar system, and the fine details of double stars.

Lanthanum optics for uncompromising image quality

The Vixen SLV eyepiece uses a 7-element optical design made from high-quality lanthanum glass. As an optical material, lanthanum is characterized by a high refractive index and low dispersion, which in practice means minimal chromatic aberration and excellent color rendition across the entire 50° field of view. All air-to-glass surfaces are fully multi-coated with anti-reflection coatings, resulting in exceptionally high light transmission. The images are truly "clean" - free from stray reflections and ghosting, with maximum contrast.

Comfort for long observing sessions

The SLV series is designed with observers who spend long hours at the eyepiece in mind. The generous 20mm eye relief allows comfortable viewing even for eyeglass wearers without having to remove their glasses. The twist-up eyecup lets you precisely adjust the eye distance from the eyepiece to suit your individual needs.

Universal compatibility

Thanks to the standard 1.25″ barrel diameter and an integrated filter thread, this eyepiece is fully compatible with the vast majority of telescopes and accessories available on the market. It accepts common filters such as:

• Lunar filters
• Planetary filters
• Other standard 1.25″ threaded filters

Who is the Vixen SLV 4mm ideal for?

The SLV series is an ideal choice for planetary observation and is equally well suited to detailed study of the lunar surface or splitting close double stars. The combination of precise lanthanum optics, thoughtful ergonomics, and universal compatibility makes this eyepiece a long-term investment that will serve you faithfully for many years. If you want to get the most out of your telescope, the Vixen SLV 4mm eyepiece is a choice you will not regret.
