Vixen SLV 10mm eyepiece - 50°, 1.25″
The Vixen SLV series has earned a strong reputation among amateur astronomers for delivering outstanding planetary views thanks to premium lanthanum optics paired with a practical, well-thought-out design. The 10mm focal length model with a 50° apparent field of view is an excellent choice for anyone who wants to get the most out of every observing session.
7-element lanthanum optics - precision and clarity
The Vixen SLV 10mm eyepiece features a 7-element lanthanum optical design that delivers exceptional colour fidelity and high light transmission across the entire field of view. Full multi-coating on all optical surfaces minimises reflections and scatter, resulting in images that are sharp, high-contrast and rich in fine detail. Whether you are observing planetary cloud bands, lunar craters or close double stars, the view remains clean and free from chromatic fringing or ghost images.
Comfortable viewing - even with glasses
A generous 20mm eye relief, combined with a smooth twist-up eyecup, makes this eyepiece well suited for extended observing sessions. Eyeglass wearers can keep their glasses on and still enjoy the full 50° field of view without vignetting or discomfort. The eyecup locks securely in both the raised and lowered positions, so you can find your preferred position quickly and maintain it throughout the session.
Standard 1.25″ filter thread - versatile and ready to use
The barrel is machined to the standard 1.25″ diameter and includes a filter thread, making this eyepiece fully compatible with the vast majority of telescopes and all standard accessories. The 1.25″ filter thread is particularly useful for planetary and lunar observation, allowing you to attach colour filters, a Moon filter or a polarising filter to enhance contrast and bring out surface detail. No adapters required - simply screw in your chosen filter and you are ready to observe.
Who is this eyepiece for?
The Vixen SLV 10mm is a well-rounded eyepiece that suits a wide range of observers and instruments:
- Beginners looking for their first high-quality lanthanum eyepiece
- Experienced observers who want a reliable planetary eyepiece with consistent optical performance
- Eyeglass wearers who need generous eye relief without sacrificing field of view
- Visual observers focused on planets, the Moon, double stars and tight star clusters
- Anyone building a collection of eyepieces and looking for a dependable mid-range focal length
