| Imagine the flat-field performance and color correction offered by our GeminiŪ 20x80 TWP's triplet objective lenses. For the amateur astronomer or the long-range terrestrial observer, the value and quality offered by this design is tough to argue with.
Everything about these instruments says "quality." Their attractive rubber armoring and hefty all-metal CNC-machined and cast aluminum construction is guaranteed to last for many years to come. The optical quality measures up to that of the precision mechanics, which makes these excellent instruments for astronomical use. The center focus (CF) model is also oustanding for wildlife observation. Optics are fully broadband multi-coated, and prisms are crafted from high-index BaK4 glass. Collimation can be adjusted by experienced users, if necessary. Each binocular is covered by our two-year warranty and 30-day return policy.
Every Garrett Optical binocular must pass a rigorous 14-point inspection that insures a high degree of both optical and mechanical performance, including accurate collimation. Any necessary adjustments are performed by a highly experienced technician on a U.S. Navy Mark V Collimator. An added perk is that every Gemini Waterproof binocular comes with a deluxe heavy-duty carrying case with durable PVC armoring and aluminum trim. The cases are lined with soft, "egg-crate"-style foam for maximum protection.
Our 7 lb., 8 oz. 20x80 TWP binoculars utilize triplet objectives for outstanding performance across their 3° field. At night, the high-resolution optics will reveal Jupiter's moons and stunning detail in our own moon's craters. But where binoculars really excel is deep space observation, and these 20x80's will reveal star clusters, nebulae, and the brighter galaxies as only a binocular can show them. Both the 20x80 TWP-IF and 20x80 TWP-CF feature a heavily-constructed aluminum center brace with a built-in rubber-footed tripod adapter for easy mounting. The IF version utilizes smooth, CNC-machined individual focusers that provide the precision focusing essential for maxium performance on astronomical targets. A new feature on the IF version is the integration filter threads into the eyepiece assembly, to allow the use of any standard 1.25" nebula or moon filter. This is a great new feature for amateur astronomers that has the potential to enhance the observing experience. The CF version uses a high-quality conventional center focus arrangement with twist-up eyecups and a right diopter, for those who plan to use their binoculars for terrestrial as well as astronomical observation.
