9mm Reference Class Eyepiece with unsurpassed apparent field of view and excellent sharpness
- These eyepiece offers a unmatched gigantic apparent field of view that gives the observer a panoramic visual experience.
- Each 120° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus.
- This also maximizes the life of the internal coatings.
- To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.
- All 120° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
