Product Description

BEDROCK OF THE SERIOUS OBSERVER’S TOOLKIT – Celestron Granite ED Series Roof Prism Binoculars represent the core values of rock solid binocular design, ultra-high performance glass and reliable construction at an affordable price. The ED lenses ensure that each wavelength of light is kept in balance with all the others to provide an image which is true-to-life. They are also useful in lowlight situations helping you to pick out details in subjects in dense brush even at dawn and dusk. They stand up well against the much more expensive European and higher end Japanese manufactured binoculars at a fraction of their cost – a real value! EXTRA LOW DISPERSION GLASS – Granite Binoculars feature ED (Extra-Low Dispersion) glass, delivering edge-to-edge sharpness with excellent color correction and razor sharp images while virtually eliminating chromatic aberration. Coupled with fully broadband multi-coatings the optical design delivers crisp, high contrast images with accurate color reproduction for unrivaled image quality superior to standard optical glass. FULLY MULTI-COATED OPTICS AND BAK-4 PRISMS – The Phase Coated Prisms correct out-of-phase shifts of light rays to ensure maximum contrast while providing superb natural color fidelity and vivid color saturation. High grade BaK-4 prism glass renders sharp images and the reflectivity coatings increases the throughput transmission to provide bright images that are rich in detail. LIGHTWEIGHT, WATERPROOF CONSTRUCTION – State-of-the-art modern open frame style provides an excellent grip and is comfortable to handle (even single handed) with the reduced weight. The body is made of magnesium alloy which is lighter than aluminum, and more rugged and tough for handling in any environment. They are a mid-sized binocular, perfect for travel because of their weight and small form factor yet are packed with features that match up well optically, mechanically and ergonomically with binoculars costing two to five times as much. Metal Twist Up Eyecups: More durable and a longer life than plastic eyecups. Less susceptible to breaking. Twist-up eyecup for correct positioning of the users eyes for comfortable viewing with or without eyeglasses. Waterproof construction provides peace of mind when unexpected weather rolls in. The housing is also filled with dry nitrogen gas to prevent the internal lenses from fogging when moving between extreme temperatures or when using the binocular in damp conditions. PERFECT FOR: Bird Watching, Hunting, Wildlife and Nature Viewing, Travel and Outdoors, Sporting Events, Astronomical Viewing, Low Light; Extended Use; Changing Weather Conditions
