  • Huge apparent field of view not only gave the observer a hugely enjoyable panoramic visual experience, but they also relax the eye so the observer can pay attention to subtle details for extended periods.

  • Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas.

  • This also maximizes the life of the internal coatings.

  • Every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.

  • All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
