Giant binoculars for astronomy and nature watching


Great for viewing the night sky or for high magnification views of land based objects.

These giant binoculars feature larger-than-normal prisms, giving full-aperture viewing. They gather much more light than an everyday pair of binoculars, and have much greater resolving power. 50% more aperture than the 20x80 binoculars

The quality optics and full anti-reflection coatings give you a bright view with a wide field of view for stargazing.

They use porro prisms, which are better than roof prisms for astronomical observing because of of their greater light transmission. The prisms are made of BAK4 glass, which is higher quality than the borosilicate flint glass used in cheaper binoculars.

Includes a hard aluminium carry case.

A tripod is recommended for a stable view.

Recommended for

General purpose use on land, and for people who want something that is easier to use than a small telescope.
