Code: 37203 SLV series 4mm lanthanum eyepiece 50 deg FOV with solid anti-roll body for lunar and planetary observers
The Vixen SLV eyepieces feature long 20mm eye relief and extremely high-grade lanthanum (rare-earth-element) glasses to minimise aberrations (spurious colours). Lenses are fully multicoated to reduce reflections and improve light transmission for high contrast views and elimination of ghost images. With twist-up click-stop eyecups they are perfect for those who wear eye eyeglasses and help shield unwanted and distracting external light sources.
-The twist-up eyecup off a comfortable viewing position to your eye.
-The eyepiece body is made of solid metal. The eye guard and gripping part are made of rubber.
-Fully multi-coated optics.
-Quality Lanthanum glass is used for clear and high contrast images.
