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 Binocular yields 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 is a wide angle of view, long eye relief, and comfortable exit pupil. A pair of removable angled eyecups is 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

  • Large knurled center focusing knob
  • 54-75mm interpupillary adjustment range
  • Right-eye dioptric correction allows for eye prescription
