The Celestron binocular features their proprietary multi coating
system to reduce reflection and increase light transmission through the entire
optical system. The porro prism configuration provides a rich depth of view and
high contrast of Celestron binoculars to draw users into an
immersive observational experience. Filter threads on the eyepieces are
compatible with astronomical filters to enhance the viewing experience by
adding light pollution, neutral density, or colored filters.
The combination of optical coatings, prism, over objectives,
and the ability to use filters produce user specific high contrast views that
are bright and crisp. The binocular and a lens that porro prism optical path
optics increases light transmission for bright high contrast images. To help
reduce weight, the binocular housing is made from a combination of
poly carbonate polymer and aluminum. The aluminum provides strength in key
areas, while the poly carbonate is temperature resistant to limit expansion and
contraction in extreme temperatures, which can cause the optical components to
move out acclimation and preventing the ability to achieve sharp focus.
Large objectives and long optical tubes make the heavy with
a center of gravity biased forward, so hand-holding it may cause fatigue and
noticeable tripod adapter to mount the instrument, with a detachable rail for finder
scope.
