Explore Scientific 17mm 92° 2-inch O.D. Argon-Purged Waterproof Eyepiece

The 17mm Explore Scientific 92° eyepieces are hyper-wide class oculars that can transform your visual astronomy experience.

With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes, objects will stay in the field of view for a very long time before any need for adjustment.

Features:
  • 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.
