The ultrawide 82° field and Argon-purged waterproof nature and superb coatings all combine to make this series the "Everyman's Series", useful on every target from close double stars to the very largest star clusters.  A superb series for the stargazer. Vixen’s NEW SLV eyepieces feature fully multi-coated lenses in a full metal body, high quality lanthanum glass, a scratch resistant lens surface, eye relief of 20mm, a twist up eye cup and a unique shape that is easy to grip and will not roll.
