Fujiyama HD-Orthoscopic Eyepieces
 
Fujiyama HD-OR Eyepieces

   Kokusai Kohki continues the tradition of offering the highest quality Japanese made Orthoscopic eyepieces with the introduction of our brand new FUJIYAMA HD-OR eyepiece line up. Fujiyama HD-ORs are hand crafted at our Tokyo factory, and individually inspected by us before we ship.

   Named after the Japanese name for that sky reaching symbol of Japan, Mt. Fuji, the FUJIYAMA HD-ORs come standard with multi-coatings on all four air to glass surfaces, giving them extended light throughput, and brighter images overall, as compared to our previous OR eyepiece line up. And all lenses are edge blackened to reduce internal light scatter and reflections to an absolute minimum. (And, for the record, cemented lens surfaces are UNcoated).

   The entire Fujiyama lineup is parfocal, accepts standard 1.25" filters, and comes with plastic eyepiece caps. The chrome barrels of the Fujiyama HD-ORs are straight up and down, and we have removed the helpful, but also often annoying, safety groove.

   Solid construction, bright, cleaner and sharp views throughout a fully corrected 42 degree FOV with sharp field stops, makes the Fujiyamas perfect for every type of viewing, and are also an excellent match with high end apochromats for hard core planetary, lunar, solar and double star viewing.

   Each eyepiece carries a one year Kokusai Kohki parts and labor warranty.

"Our promise to you: you will either LOVE your FUJIYAMA HD-OR eyepiece or you get your money back!"
