CELESTRON GRANITE 9X33ED

The Celestron Granite ED Series roof prism binoculars represent the core values ​​of rugged binocular design, featuring ultra-high performance glass and reliable construction at an affordable price. ED lenses ensure that each wavelength of light is balanced, providing a true and natural image. They're also useful in low-light situations, helping you pick out details at sunrise and sunset, even among dense trees. They perform well at a fraction of the cost of European and high-end Japanese-made telescopes - a real bargain!

Ultra-low dispersion glass

Granite telescopes feature ED (Extra-low Dispersion) glass, which provides edge-to-edge clarity, excellent color correction and sharp images that virtually eliminate chromatic aberration. Coupled with full-band multi-layer coating, the optical design provides clear, high-contrast images with accurate color reproduction and unparalleled image quality that far exceeds ordinary optical glass.

Fully multi-coated optics and BaK-4 prisms

Phase-coated prisms correct the phase shift of light, ensuring maximum contrast while delivering outstanding natural color fidelity and vibrant color saturation. Premium BaK-4 prism glass delivers razor-sharp images, and a reflective coating increases transmission, delivering bright images with rich detail.

Lightweight, waterproof construction

The modern open frame style provides a great grip and is lightweight and comfortable even for one-handed operation. The body is made of lighter magnesium alloy, which is lighter and more durable than aluminum, making it suitable for use in any environment. They are mid-sized telescopes that are ideal for travel due to their light weight and small size, but are packed with optical, mechanical, and ergonomic features that match telescopes that cost two to five times their cost. Waterproof construction provides peace of mind during sudden inclement weather. The case is also filled with dry nitrogen to prevent the internal lenses from fogging when moved between extreme temperatures or used in humid environments. Metal rotating eyeglass rings: more durable and longer lifespan than plastic eyeglass rings. Not easy to break. Rotating eyeglass rings allow the user's eyes to be correctly positioned for comfortable viewing with or without glasses.
