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 on shorter focal length telescopes, especially good for Lunar viewing - or for those trying to max out their longer focal length scopes for double star work.
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.
