TAKAHASHI
TAKAHASHI LE & Hi-LE Eyepieces

There are several types of eyepieces in the market. Some look very good; some have long eye-relief; some are sharp; some are cheap; some are expensive! However, when it comes to the highest contrast, maximum sharpness, high light transmission, good eye-relief and the best colour rendition, the Takahashi "LE" and "HI-LE" eyepieces have no rivals!

Below are a few comments from an expert amateur astronomer, who wrote a three-page test report on the Takahashi "LE" oculars.

Under test the LE Series oculars provided:

* Increased light transmission through the eyepiece. In other words all the LE oculars provide a brighter image;
* Increase in contrast in every case;
* Sharper images in every case;
* Increase resolution in every case.

The LE series improved every object throughout all the focal length ranges, and in comparison to both standard Plossl field of view and wide-field oculars. This is in brightness, contrast, image resolution and detail of bright and faint objects!

"...I cannot forget when, about two years ago, I had trouble splitting the double star Antares with my Takahashi FS-102 FL refractor, using five different well-known 7.5mm oculars. I started thinking that the said refractor wasn't as good as I thought. Eventually, it dawned upon me that may be I wasn't using the best oculars for the job. However, all my worries disappeared as soon as looked through an LE 7.5mm ED ocular, which fortunately I had still in stock. Antares' green companion, 7th-magnitude star, was there in all its glory!"
(Claude Voarino AEC, 2013)

FUJIYAMA
FUJIYAMA HD ORTHOSCOPIC 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!"
