Nikon NAV HW 12.5 mm eyepiece with corrector EiC-10Riding the wave of their international success with the NAV-SW series eyepieces, Nikon now offers the new hyper wide 102 degree FOV NAV-HW eyepieces. This series consists of two focal lengths, the 12.5 mm NAV-12.5HW and the 17 mm NAV-17HW. Each eyepiece also includes the unique benefit of an "EiC" tele-extender lens, specifically designed for each eyepiece, that shortens the focal length to 10 mm. Which means you are actually getting two eyepieces for the price of one.
The NAV-12.5HW is a 1.25" eyepiece that includes a 2" screw on barrel. All surfaces are multicoated with world class Nikon coatings and the mechanical and cosmetic finish is, well, perfect, as you would expect with any Nikon product.
