Details
The Oceana Series from Celestron features waterproof models for marine use. Choose from three feature-rich models - whether you want center focus, traditional individual focus, or a model with a compass and reticle. All are rubber covered to protect against rough handling.
The individual focus model allows for precise focus adjustments to allow for differences in the prescription of each eye. All provide maximum optical performance with BAK-4 prisms and multi-coatings for sharp images with high contrast and resolution. Each model has a large, 50mm objective lens to offer maximum image brightness even in low light conditions, like dusk and dawn. For additional convenience, each model features attached objective lens protective caps.
* Completely waterproof - dry nitrogen charged and sealed with internal O-rings to prevent internal fogging - unaffected by climate and temperature changes
* Individual eyepiece focus with diopter scale for quick and accurate focusing
* Excellent depth of field for minimal focus adjustments
* Nautical style padded canvas case and straps
* Attached objective caps
* Tripod adapter fitting for tripod mounting
* Limited Lifetime Warranty
