The Vixen SLV series are the modern take on the classic Vixen Lanthanum eyepieces. These eyepieces were legendary for their generous eye relief and precise nature, making them a firm favorite with planetary, lunar and double star observers. This 4mm is an excellent higher power eyepiece for most telescopes, especially good for Lunar and Planetary observers.
The SLV Series of Vixen Eyepieces feature a hexagonal shaped eyepiece barrel, long 20mm eye relief, and twist up click stop eyecup for adjusting to the most comfortable viewing. The SLV eyepieces feature high-grade lanthanum glass, and deliver remarkably clear and high-contrast star images to the edge of the viewing circle. The lenses are fully multicoated for high light transmission.
