3D Astronomy - 8x42 Space Walker 3D Binoculars

Summer Binocular Buying Guide

Built with the proprietary Lederman Optical Array (LOA) to reproduce the true stereoscopic depth of field of human sight, 3D Astronomy's 8x42 Space Walker 3D Binoculars yield views of the night sky that normal binoculars cannot offer. The LOA duplicates the physiological process that allows humans to see with depth perception and eliminates the flat depth of field common when viewing through binoculars focused at infinity. The LOA is complemented by phase-corrected and dielectric coated BAK4 roof prisms and fully multi-coated optics that work together to improve light transmission throughout the optical path, reduce internal light scattering, and increase color rendition, image clarity, and overall contrast. Rounding out the optical performance are a wide angle of view, long eye relief, and comfortable exit pupil. A pair of removable angled eyecups are provided to block peripheral light and eliminate ambient light interference with your viewing experience.

Optical Performance

8x magnification

42mm objective lenses

Compact BAK4 roof prisms

Phase-correcting prism coatings reduce internal light scattering while aligning light waves to improve contrast and clarity

Dielectric prism coatings reduce light loss for brighter images

Fully multi-coated optics reduces light loss and increases color rendition, contrast, and clarity

Wide 60° apparent angle of view

388' field of view at 1000 yards

Long 17.5mm eye relief

Wide 5.25mm exit pupil

Lederman Optical Array

Optical array integrated into one eyepiece

Duplicates the physiological process that allows humans to see with depth perception

Eliminates the flat view typical when viewing through binoculars focused at infinity to produce a rich depth of field more like natural human vision

Produces the angular offset required for true stereoscopic vision no matter how far the field being viewed is located

Use and Handling

Closed-bridge configuration

Large knurled center focusing knob

54-75mm interpupillary adjustment range

Right-eye dioptric correction allows for eye prescription

Twist-up rubber eyecups for comfortable use with or without eyewear

Removable angled eyecups block stray peripheral light making images clearer and brighter

Construction Details

Lightweight and strong magnesium alloy chassis

Slip-resistant protective rubber armoring

Nitrogen-filled for water and fogproof performance

Weight: 22 ounces
