20 x 80mm Premium Binoculars

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

The 80mm lens, plus the larger-than-normal prisms, means these binoculars gather three times more light than an everyday pair of 10x50mm binoculars, and 20% more than our 20 x 80mm standard binoculars.  

The quality optics and full anti-reflection coatings give you a bright view with a wide field of view for stargazing (the 3.2 degree field of view is about six times as wide as the moon). 

They use porro prisms, which are better than roof prisms for astronomical obseving 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.

These giant binoculars have individual focusing eyepices and come with a hard aluminium case.

A tripod is recommended to give 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.
