The Orion 9x63 Mini Giant Astro Binoculars has lenses and high-grade BAK-4 prisms which are fully multi-coated to permit the highest light transmission possible. The aluminum barrels are internally glare-threaded to ensure rich contrast and eliminate ghosting. Images are sharp, bright and wonderfully vivid. Moderate, 9x magnification allows a wide 5.0° field and 7mm exit pupil.
Contributing to this binocular's comfort factor is its long eye relief. No pressing the eyepiece housings into your eye sockets to get the full field of view. Even eyeglass wearers will see edge to edge. Its relatively compact size, allow this Mini Giant 9x63 binocular to be hand-held comfortably for short viewing stints.
That applies to daytime use as well. For extended gazes, especially with the two high-power models, you'll want to tripod-mount the binocular for steady images. Smooth rubber armoring provides a secure grip. A large, knurled center focus wheel, pop-down rubber eyeguards and threaded socket for optional tripod adapter round out the feature set.
