The 15-45x65mm WP Naturescape ED Spotting Scope from Barska is provisioned with premium optical quality. The ED, Extra Low Dispersion glass furnishes exceptional clarity, contrast and resolution by minimizing chromatic aberration and commonly found visual distortions. Phase coating adds to the resolution by phase shifting or correcting the prisms reflected light. This results in an optimized optical path for the size and aperture of the scope. Fully multicoated optics and BAK4 Porro prisms deliver clear, crisp viewing. It is waterproof and fogproof for use in all weather conditions and comes with a table top tripod. This is an enhanced optical scope with superior light transmission that still retains the rugged dependability necessary for quick mobility.
