Orion 25x100 Giant View, Weather Resistant Porro Prism Astro Binocular with 2.5 Degree Angle of View.

The Orion Giant View 25 x 100 Astronomy Binoculars has large-aperture, fully multi-coated optics which provide exceptional light gathering capability for stargazing. And if terrestrial observing is more your speed, you will appreciate this GiantView's long-distance range, wide field of view and stunning resolution.

The GiantView 25x100 Large-Aperture is a wonderfully well made binocular. The BAK-4 prisms and internal baffling ensure sharp images and pleasing contrast. The barrels are cross-reinforced with an aluminum rod and objective cell cuffs for maximum structural rigidity and unflinching optical alignment. A sliding 1/4"-20 mounting post is held captive on the rod, for coupling the binocular to a tripod (recommended) and achieving optimum balance.

This binocular provides a generous 4mm exit pupil and the serious magnifying power you need to resolve subtle details in your target object. The eyepieces focus individually, which affords a higher degree of focusing precision than center-focus mechanisms. And the long eye relief even lets eyeglass wearers see an unrestricted field of view. It includes heavy-duty aluminum case.
