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. Utilizing technology developed with the Ethos eyepieces, the Delos eyepieces' 72° field produces unsurpassed sharpness from edge to edge--perfect for lunar, planetary, AND deep-sky use.  Comfortable for glasses wearers and non-glasses wearers alike because of an innovative eyecup design.
