Are you a serious amateur astronomer looking for the best and brightest wide-field images of the night sky with binoculars? The Orion 20x80 ED GiantView Binocular will fit that bill! These binoculars combine a large 80mm aperture withExtra-low Dispersion (ED) glass lenses for bright, exceptionally clear, true-color views of the night sky. Not to mention these binoculars work equally well for long distance daytime viewing. All of this in a waterproof body, with BAK-4 prisms, robustmechanical construction, and a solid pier tripod mounting system. And all these features for a very reasonable price.You'll understand the combination of large aperture and ED lenses the first time you scan the Milky Way - pinpoint stars, with exceptional contrast against a dark background.

And these binoculars boast a 3.2-deg field of view for scanning the skies, or watching distant wildlife.The sturdy aluminum alloy body with a second hinge between the objective lenses provides a solid, well collimated mechanical system.
