Explore Scientific 68° Series Eyepieces

Explore Scientific 68° Series eyepieces give a wide 68° apparent field in a waterproof, argon-purged body. The 16mm, 20mm and 24mm models use 1.25" barrels, and the 28mm, 34mm and 40mm are 2" eyepieces for low magnification and the widest true field your telescope allows.

The series centers on medium and long focal lengths, so it pairs well with a shorter eyepiece for planets. It suits deep-sky observers framing open clusters, large nebulae and Milky Way star fields.
