Employing the best optical designs and superior waterproof construction, the Vixen 20x80 Giant is an exceptionally good astronomical binocular.  Its display of the sky will dazzle you.  All the binoculars in this Giant series are very large units, that require a great tripod.   But if you'd like to really see what those faint fuzzies are above you, then you can't do much better than with these true Giants.  The 20x80 requires darker skies than would the 12x or 16x versions, but can also yield better resolution of the smaller-sized objects in the skies.
