Garrett® Gemini 20x90 WP-IF Binocular

I believe these 20x90's are a good balance of power in an instrument that is about the largest that I would consider easy to observe with... (click for more).

More aperture than a 20x80, lighter weight and a wider field of view than a 25x100 - meet the new Gemini® 20x90 WP-IF. This binocular represents the middle ground between two of our most popular binocular sizes.

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. 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 8.4-lb. Gemini 20x90 WP-IF binoculars offer 3° field of view that is significantly wider than the 2.4° offered by our 25x100's. 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 20x90's feature a 4.5mm exit pupil that provides a brighter image when observing nebulae and galaxies - you'll see these objects as only a binocular can show them. The 20x90 WP-IF features a heavily-constructed aluminum center brace with a built-in rubber-footed tripod adapter for easy mounting. It utilizes smooth, CNC-machined individual focusers that provide the precision focusing essential for maxium performance on astronomical targets. A bonus 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 feature for amateur astronomers that makes an already great deep space observation instrument even better.
