Explore Scientific 14mm 100° 2-inch O.D. Argon-Purged Waterproof Eyepiece

The 14mm Explore Scientific 100° Series eyepieces are hyper-wide class oculars that will transform your viewing experience.

With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are easier to locate, and for non-driven telescopes, the object will stay in the field of view for a very long time before you need to make any adjustments.


  • Great for viewing celestial objects by using averted vision
  • The fold-down rubber eyecup prevents stray light from leaking into the eye, further boosting contrast.
  • The eyepiece is internally sealed and purged with inert, dry argon gas, which maximizes the life of its internal coatings.
  • The eyepiece is tested by submerging it down to 1 meter of water for 30 minutes.
  • Fully multi-coated and edge-blackened to produce maximum contrast.
