Description

The Oceana marine binocular from Celestron is a waterproof binocular designed for marine use but it’s also useful for various land based observations as well.

This feature-packed model includes an illuminated compass for direction finding, reticle for distance measurement, and a convenient center focus system. Maximum optical performance is appreciated with the BaK-4 prisms and fully multi-coated optics for ultra sharp images with high contrast and resolution. It has a large 50mm objective lens to offer maximum image brightness even in low light conditions, like dusk and dawn.
