Home Eyepieces Fujiyama HD Orthoscopic Eyepieces Fujiyama HD Orthoscopic Eyepiece 5mm
Orthoscopic eyepieces have long been regarded as an excellent no compromise design for purists demanding the maximum light transmission and contrast for detailed planetary observation. These Fujiyama HD Orthoscopics are made in Tokyo Japan by Kokusai Kohki with the latest optical and coating technology ensuring you of the best possible performance. Every single one of these premium oculars is individually inspected in the Tokyo factory prior to shipping reassuring you that every one meets the top specification.A short focal length ocular, ideal for faster telescopes with focal lengths less than 1000mm
All lenses are edge blackened to reduce internal light scatter and reflections to an absolute minimum in keeping with the high contrast design. 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 that can cause issue with compression clamps in diagonals or focusers. Solid construction, bright, clean 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.
