Celestron 15x70 SkyMaster Pro Porro Prism
Binocular:
Designed as an ideal optic for wide-view
astronomical or long-range terrestrial observation, the Celestron 15x70
Binocular features their proprietary XLT multicoating 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
to draw users into an immersive observational experience. Filter threads on the
eyepieces are compatible with 1.25" astronomical filters to enhance the
viewing experience by adding light pollution, neutral density, or colored
filters. The combination of optical coatings, prism, over-sized 70mm
objectives, and the ability to use filters produce user-specific high-contrast
views that are bright and crisp. The binocular features a 15x magnification and
a large 70mm objective lens that incorporates BAK4 porro prism optical path.
Proprietary XLT fully multicoated optics increases light transmission for
bright high-contrast images. To help reduce weight, the binocular housing is
made from a combination of polycarbonate polymer and aluminium. The aluminium
provides strength in key areas, while the polycarbonate is
temperature-resistant to limit expansion and contraction in extreme temperatures,
which can cause the optical components to move out collimation and preventing
the ability to achieve sharp focus. Large objectives and long optical tubes
make the SkyMaster Pro fairly heavy with a centre of gravity biased forward, so
hand-holding it may cause fatigue and noticeable hand-shake. A centre
stabilizer bar has a built-in 1/4"-20 tripod adapter to mount the
instrument, with a detachable rail for a red-dot finderscope. To handle a wide
range of environments, the optical tubes are nitrogen-filled and O-ring sealed
to be water and fogproof. Rubber armor protects against impacts and provides
slip-resistant grip.
