Vixen NPL Plossl 30mm eyepiece 50° 1.25″
Looking for an eyepiece that offers genuinely good optics without overpaying? The Vixen NPL Plossl series was created exactly for astronomers like you - a collection of four-element eyepieces that combines an affordable price with surprisingly high optical quality. The 30mm focal length model is an excellent choice for wide-field sky surveys, object finding, and observing extended nebulae and star clusters.
Classic Plossl design with modern coatings
The optical design is based on the classic four-element Plossl scheme, which is popular among astronomers for its well-balanced performance - a good field of view, a comfortable exit pupil, and a reasonably short eye relief. All optical surfaces are treated with fully multi-coated anti-reflection coatings (FMC), which minimize unwanted reflections and stray light. The result is high light transmission and excellent contrast - details in nebulae and star clusters appear with pleasing sharpness and faithful brightness reproduction.

What the 50° field of view gives you
A 50° apparent field of view is the standard for Plossl eyepieces and provides a comfortable overview of the observed area of the sky. The eyepiece accepts standard 1.25″ astronomy filters - UHC, OIII, or colored planetary filters all fit directly with no adapter needed.
Lightweight and compact - great for binoviewers
One of the practical advantages of the entire NPL range is its low weight and compact build. This is especially important when used in binoviewers, where the balance of two eyepieces matters a great deal. The lightweight NPL eyepieces put much less strain on the telescope's focuser than heavier wide-field alternatives, while still providing comparable observing comfort. Of course, they work equally well in standard single-eye use on refractors, reflectors, or catadioptric telescopes.
Who is this eyepiece for?
The Vixen NPL 30mm is a great match for:
- Beginners looking for their first quality eyepiece for overview observations
- Experienced astronomers who want a reliable, lightweight long-focal-length eyepiece for object finding
- Users of binoviewers who need a well-balanced, compact pair of eyepieces
- Anyone who needs a versatile eyepiece compatible with virtually all telescopes and accessories
A straightforward tool you can rely on
The Vixen NPL Plossl 30mm eyepiece is an honest and functional instrument - no unnecessary compromises, a reasonable price, and optical performance you can count on night after night. Thanks to its standard 1.25″ barrel and universal filter thread, it is fully compatible with the vast majority of telescopes and accessories available on the market.
