Features

Vixen SLV 20 mm eyepiece with 1.25" / 31.8 mm barrel size (Two eyepieces included)

The Vixen SLV range offers maximum comfort with their generous eye relief of 20 mm. The eye lens has a diameter of 20 mm, too, so eyeglass wearers have the full field of view. Vixen's SLV eyepieces are the right choice for observers who want high definition and a relaxed viewing position. With the integrated twist-up eyeguard, your individual eye relief can be adjusted easily.

All glass/air surfaces are hard multi coated for a minimum of reflexes and ghosting. At the same time, the light transmission is optimized. Of course all lens edges are blackened.
