Product Details

  • The Orion GiantView ED 20x100 Waterproof Astronomy Binoculars has massive 100mm fully multi-coated lenses that pull in faint light from the night sky, and the ED (extra-low dispersion) glass lenses produce a high contrast and tact sharp image with minimal false color. Scanning the Milky Way to discovering hidden gems is what these binoculars were built for! But of course, they are also excellent for long distance daytime viewing as well.

    20x magnification eyepieces really help to pull in distant targets, and with a 5mm exit pupil you can see a brighter view of extended objects in the night sky (such as nebulae and galaxies) compared with a similar aperture binoculars with only a 4mm exit pupil. Having that larger exit pupil really helps optimize these binoculars for deep-sky viewing!

    An eye-relief of 20mm means even if you wear glasses, you'll be able to see the entire 3.3° field of view without taking those glasses off. BaK-4 prisms and internal baffling help ensure top notch optical quality. And the all-metal binocular housing is rock solid, with a tripod pier mounting post and rod that also doubles as an objective lens cross-bridge to hold the optical elements solidly in place. Rubberized surface coverings provide a comfortable and non-slip grip.

    The tripod mounting bar clamps to the central support rod and attaches securely to a standard photographic tripod. Note that these binoculars weigh 9.2 lbs., so a solid and well-made photo tripod or parallelogram mount is highly recommended! Includes lens caps, tripod pier adapter, and a hard carrying case with foam cutouts to securely protect your giant binocular.
