50x WA Eyepiece for High Lander, 1 piece

The eyecups are located on the eyepieces and protect they eyes from stray light.

Watertight optics are equipped with special seals and are gas-purged. This is usually with nitrogen or argon gas. Since these gases are heavier than air, they cannot escape.

These eyepieces have a relatively large eye relief. It is possible to wear spectacles while observing and still benefit from a comfortable viewing position.
