Vixen Binoculars BT-81S-A (45518)

Viewing the night sky through large-aperture binoculars creates a unique and immersive experience. Celestial objects appear almost three-dimensional, and well-known nebulae, globular clusters, and open star clusters look truly spectacular. With interchangeable eyepieces and upright images, you can explore a wide range of targets, from deep-sky Messier objects to terrestrial landscapes. The BT-81S-A uses two achromatic lenses, each made from two elements with natural multi-coating. Magnesium fluoride coatings help reduce chromatic aberrations.

Description

Viewing the night sky through large-aperture binoculars creates a unique and immersive experience. Celestial objects appear almost three-dimensional, and well-known nebulae, globular clusters, and open star clusters look truly spectacular.

With interchangeable eyepieces and upright images, you can explore a wide range of targets, from deep-sky Messier objects to terrestrial landscapes.

The BT-81S-A uses two achromatic lenses, each made from two elements with natural multi-coating. Magnesium fluoride coatings help reduce chromatic aberrations. The focal length of 480 millimeters gives the instrument a fast aperture of f/5.9, making it excellent for viewing wide gaseous nebulae, star clusters, and comets.

The set includes a carrying handle, viewfinder shoe, dew shields, and dust caps. Eyepieces are not included, but any standard 1.25" eyepieces can be used.

Please note: The binoculars are supplied without eyepieces.
