Vixen SLV 12mm 1.25" Long Eye Relief Eyepiece

The Vixen SLV 12mm 1.25" Long Eye Relief Eyepiece is a high-quality eyepiece designed to deliver sharp, high-contrast views with excellent viewing comfort. Manufactured in Japan, it reflects Vixen’s reputation for precision optics and is well suited for lunar, planetary, and general deep-sky observing at moderate magnifications.

Sharp, High-Contrast Optical Performance

The SLV 12mm features fully multi-coated optics that maximise light transmission while reducing internal reflections and glare. This results in bright, crisp images with accurate colour reproduction and well-defined detail across the field of view. The controlled optical design provides reliable performance for both detailed lunar observation and wider deep-sky targets.

Comfortable Long Eye Relief Design

A key advantage of the SLV series is its generous long eye relief, which allows relaxed viewing during extended observing sessions. This makes the SLV 12mm particularly suitable for eyeglass wearers. The adjustable rubber eyecup includes click-stop positions, enabling precise eye placement and a stable, comfortable viewing position.

Optimised Apparent Field of View

The eyepiece offers a 45° apparent field of view, optimised for distortion-free, controlled observation. This field size provides a clean, well-framed image that is especially effective at moderate magnifications, making it easy to concentrate on fine detail without distractions at the edge of the field.

Practical and Durable Construction

The eyepiece body features a distinctive hexagonal design that provides a secure grip and prevents the eyepiece from rolling when placed on flat surfaces. Its solid construction and smooth 1.25-inch barrel ensure dependable compatibility with a wide range of telescopes and accessories.

Consistent Performance Across the SLV Range

As part of the Vixen SLV eyepiece series, which spans focal lengths from 2.5mm to 25mm, the 12mm model offers consistent optical quality and ergonomics. It is a dependable choice for astronomers seeking comfort, clarity, and long-term reliability in a compact 1.25-inch eyepiece.
