Vixen SLV eyepieces

Steve Ringwood takes a good look through Vixen’s SLV range of eyepieces, offered in ten focal lengths from 2.5mm to 25mm. Each is designed to offer exceptional clarity and contrast across a 45°—50° field by employing rare earth Lanthanum glass. He also notes that each eyepiece’s polygonal rubber grip acts as an ‘anti-roll’ feature, hopefully protecting them from a fall!
