Explore Scienthific 40mm 62° 2-inch O.D. Argon-Purged Waterproof Eyepiece

The 40mm Explore Scientific 62° Series eyepiece is excellent flat-field multi-element oculars that, with their apparent field of view of 62 degrees and near parfocal design, offer an excellent viewing experience.

The 62°-series eyepiece features a 2" diameter barrel that fits onto common drawtubes and accepts most eyepiece filters.

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.
