Just in, a pair each, of both the venerable Pentax XO-2.5mm and the XO-5mm Super Multi-Coated (SMC) eyepieces. In excellent, near new condtion, these four out of production, and now quite rare eyepieces, were barely used by the previous owner. The XO-5 (actually 5.1mm) is a 3-element five lens design, and the XO-2.5 (actually 2.58mm) is a 3-element, 6 lens design. FOV is 44 degrees for both, with 3.6mm eye relief for the XO-5 and 3.9mm for the XO-2.5. Size and weights are: 45mm high by 37mm diameter, 90 grams for the XO-5, 56mm high by 37mm diameter, 105 grams for the XO-2.5.

All are standard 1.25 inch barrel size, and threaded for standard filters. All come with new 3rd party (not Pentax) caps on both ends, and the original Japanese manual (sorry, no English manual available). One XO of each size comes with its own original box, and the other one does not, with a price difference set accordingly. Available first come, first served!

My usual warranty applies: you either love your (used) XO eyepiece(s), or you get your money back.

Design Illustration


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 lineup. 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 multicoatings on all four air to glass surfaces, giving them extended light throughput, and brighter images overall, as compared to our previous OR eyepiece lineup. 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, 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 exellent 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 and warranty to you is simple: you will either LOVE your FUJIYAMA HD-OR eyepiece or you get your money back!

Barry Gooley taking part in a star party on the summit of Fujiyama (Mt Fuji) way back in the end of the 20th century. Our 12" dobsonian was joinied by a 6" Fujinon binocular, a 4" Miyauchi binocular along with a number of Vixen and Takahashi telescopes. All the equipment was carried to the top and back via heavy bulldozer, with us riding on top, on a winding and hair raising mountain trail. A large numbers of very surprised climbers joined our group for 2 whole nights of fabulous viewing under transparent (though not entirely LP free) skies. Cold, windy, raw, rugged, mysterious and oxygen deprived, the summit star party was for me an amazing, rare and thoroughly greuling, experience never to be forgotten. Special thanks to our sponsors and all those who attended (and helped us carry and set up all this stuff!)






 
Kokusai Kohki Original

Correct View Finder

EF-508
(8x50mm)


Our 8th production run of the EF-508 correct view finder comes with a white tube, and is available as an OTA only, as a two piece set with a "forward sweeping" finder bracket of own design and manufacture, and as a three piece set that also includes the Baader Planetarium "Standard Bracket" foot, which will mate your finder to most any OD tube with an OD of about a 144mm to 250 mm. For tube ODs larger and smaller than these, the use of a small spacer or shim between the Standard Bracket and tube should easily allow for a decent fit.

The EF-508 uses a very well made pechan prism internally, to right the upside down image coming from the objective lens. This prism gives surprisingly clear and bright views and in no way feels inferior to the image seen thru a typical upside down finder of the same aperature. An X type reticle, marked in 1 degree increments, uses a center bubble for putting your object of interest in the center of the FOV, without covering it up. A brightness adjustable red LED that illuminates the reticle is standard with your EF-508.



EF-508 finder and its newly redesigned finder bracket, in combination with the our original finder bracket. The EF-508 finder is also available as an optical tube by itself, or as an optical tube with only the bracket. A variable brightness red LED illuminator is also standard equipment.


Though optically of significantly high quality, the correct view EF-508`s greatest claim to fame, is, well, its correct view image. Objects appear in correct up/down/left/right orientation, as if viewing them either with the naked eye, a binocular or a spotting scope.This makes correlating stellar patterns in the FOV with your star chart a snap. And reading far away billboards, street signs, etc is a breeze (no more having to stand on your head ;- )

Each EF-508 is personally inspected before shipment and is accurately focused. Of course everyone has their own focus preferences, and you can easily adjust the infinity focus, and reticle focus with some quick turns of the adjustment rings.

To help deliver the brightest possible images, all optical surfaces are fully multi-coated.

The red LED unit is delivered with two LR-41 button batteries that are easily sourced where-ever batteries are sold.

The EF-508 is a robust optic, and is slightly heavier than a standard finderscope of the same aperture. We have seen very few problems over the years with the sale of over 4000 units worldwide to date (though almost all in Japan).







The EF-508 two piece set, the optical tube with our original finder bracket, also mates with a Vixen finder saddle plate, available separately at 1,210 yen. As the Vixen finder saddle is an industry standard that is used on many modern telescopes, the EF-508 finder bracket allows users of telescopes with this saddle arrangement an easy fit, with no modifications.



Our finder bracket uses oversize plastic tipped 5mm aluminum adjustment bolts to secure the finder telesope without scratching it. And custom made thin washers lock the collimation screws once put into postion.

The EF-508 correct view finder is made in China for us to our specifications, and each unit is inspected for quality here in Japan before we ship. We market and warrant our finders on the condition that you either LOVE your EF-508 or you get your money back.

 Accessories For Vixen PORTA / PORTA II

Slewing Handle : "New Guide Handle"

Carry Bag : "PORTA Bag"



The Vixen PORTA, and newest model PORTA II alt-azimuth mounts, have taken Japan by storm and I hear that they are hot sellers all over the world. And no wonder; the PORTA mount carries a decent payload up to about 5~6, maybe 7Kg, OTAs attach easily to it with the now nearly universal Vixen dovetail plate, it has competent dual axis slow motion handles, and comes complete with a very decent height adjustable aluminum tripod, all for a quite reasonable price. And it`s rather pretty too. But we did notice one aspect of the PORTA mount that, in use, sometimes proves to be amazingly annoying .....





Aiming your PORTA mounted OTA around the sky usually means grabbing the focuser or star diagonal and then using this "handle" to point your scope. This often results in twisting the star diagonal out of alignment, getting gear grease on fingers or even having the star diagonal+eyepiece combination fall off onto the hard ground below....Yikes! At any rate, the usual method is, oh, so, well,... inelegant....And perhaps not very accurate either. And certainly not convenient....

Instead of grabbing and then man-handling the focuser, the simple addition of a robust handle to the altitude axis of the PORTA removes all this lack of finesse with a quick and easy installation. Our own "New Guide Handle", designed specifically for use on both PORTA mounts, has a foam covered grip on the end that keeps fingers warm, and lets you become the true master of your trusty PORTA mount ;-)

"New Guide Handle", for both PORTA and PORTA II mounts, attaches in about 5 easy minutes, and the necessary tools are included with your PORTA mount as it comes from Vixen. Attachment involves removing the dovetail saddle plate on the altitude axis, slipping it over the New Guide Handle, then rebolting the combination back on to the altitude axis, a very simple procedure that is also kinda fun to perform. Highly recommended for all PORTA users!!

1) Gather your implements from under the rubber cover of your PORTA`s azimuth axis

2) Use this hex wrench to loosen the screws attaching the saddle plate to the altitude axis.

3) Get your New Guide Handle in hand, along with the included attachment screws.

4) Line up the holes in the saddle plate with the New Guide Handle and insert the screws

5) With the same hex wrench, screw the saddle plate, with the New Guide Handle sandwiched between it and the mount, back onto the altitude axis 6) Installation completed in 5 minutes or less! Make pointing of your PORTA easy, intuitive, accurate and for the first time, elegant!

The PORTA Bag

For both PORTA and PORTA II mounts, we also offer a PORTA specific carry bag that perfectly conforms to the hump of the alt-azimuth head assembly, and includes an inner pocket for holding the plastic parts tray from between the tripod legs. Rugged materials and strong zippers will keep your PORTA safe for a lifetime and it sure makes transporting and storing your PORTA mount a cinch. One of our most popular items in the Japanese market, this carry bag can also contain other makers` tripods or even complete telescope OTAs like a TAK FC125 (without removing the finder).

NIKON HYPER WIDE

NAV HW Eyepieces




Riding the wave of their international success with the NAV-SW series eyepieces, Nikon now offers the new hyper wide 102 degee FOV NAV-HW series eyepieces. This series consists of two focal lengths, the 12.5mm NAV-12.5HW and the 17mm NAV-17HW. Each eyepiece also includes, at no charge!, the unique benefit of an "EiC" tele-extender lens, specifically designed for each eyepiece, that shortens the focal length to 10mm in the case of the NAV-12.5HW, and the NAV-17HW to 14mm. 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 barrrel. The NAV-17HW is a dedicated 2" eyepiece. All surfaces are multi-coated with world class Nikon coatings and the mechanical and cosmetic finish is, well, perfect, as you would expect with any Nikon product.

Either eyepiece is delivered in a big package, making airmail shipping rates are a bit on the high side. But I am sure you will find your Nikon HW to be a superb addition to your eyepiece case and your pride and joy as you train it on the night skies. Available from Nikon in 2~3 days from your order.

NIKON NAV SW Eyepieces



Hot off their optical benches, Nikon commemorated the International Year of Astronomy 2009 with the birth of their brand new and long awaited NAV-SW series eyepieces. Manufactured in five different focal lengths, all are now currently available and shippng from order

Nikon NAV SWs, based on their excellent eyepieces for Nikon spotting scopes, have evolved to meet the requirements of high level astronomical observation, with the deepest attention devoted to exquisite rendition of astronomical point sources of light, while also taking a chapter for the digiscope design world, which demands flat fields and sharp images right to the very edge of the field of view. The NAV SW design emphasizes suppresion of field curvature and all astigmatism to bring about the maximum improvement in edge of field fidelity wthout sacrificing the quality of the image at the central of field.

The compact Nikon NAV SWs are 72 degree FOV eyepieces that come with 1.25" barrels that are threaded for standard filters. The comfortable eye relief specs for each eyepiece are designed to also harmonize with the optical performance of that eyepiece. Also, removal of exit pupil aberrations virtually eliminates any instance of kidney bean blackout effect, regardless of where the eye is placed during observation. The excellent color balance of the NAV SWs was derived through rigorous testing of this optical parameter on terrestrial objects, insuring the highest degree of planetary and lunar color rendition. Multicoatings on every optical surface make sure that these images are also as bright and otherwise distortion free as possible.

The Nikon NAV SW exterior design is somewhat reminiscent of the tried and true Nikkor lens design, with an attractive, high quality appearance, and rollets located around the entire circumference making the eyepieces easy and sure to grip even in darkness, or with gloved hands. A flexible silicone rubber eye shield on the top of the eyepiece helps block streets lights and other annoying sources of light pollution, especially a help when viewing sensitive planetary and lunar surface details at high magnifications. The rubber eyeguard is painted with a unique phosphorescent logo that glows ever so slightly to help make seeing the eyepieces (or finding them) in the dark just a little easier.

Nikon NAV SWs moisture resistant design will provide long years of constant and worry free service and viewing pleasure to discriminating astronomers in any observing environment worldwide.

The combination of the ideal optical qualities of a flat and wide 72 degree FOV that is sharp from edge to edge, excellent color rendition, comfortable eye relief intelligently designed to harmonzie specifically with each eyepiece, a beautiful and compact body design, highest quality Japanese glass, multi-coatings and exterior materials, and a good selection of focal lengths, makes the Nikon NAV SWs a true and new winner in the ever expanding world of 21 century astronomy.

 Pentax Eyepieces

 




70 degree apparent field of view, Eye relief 20mm
Practically waterproof, to assure you of years of problem-free observing
Beautiful to look AT, as well as look through

Kokusai Kohki offers the fabulous Pentax XO and XW series wide angle SMC (super multi-coated) eyepiece lineup.Though not rock bottom low price, this premium eyepiece provides tack sharp and bright images to the edge of the very wide field. Adding in superior light throughput and plenty of eye relief, the XW series deserves a place in every serious observer`s eyepiece case. The Pentax XW series also offers the discriminating observer the following benefits:

* All focal lengths standardized with a dazzling 70 degree field of view, and generous 20mm of eye relief, for ease of viewing even when wearing glasses.

* A brand new design that incorporates high refractive index Lanthanum glass elements. This sophisticated design corrects and balances all optical abberrations for images that approach optical perfection. An added plus is the extra effort made to compensate for spherical aberations found in the human eye, virtually removing kidney bean and blackout effects. A truly easy to view through eyepiece.

* Proprietary Pentax multi-coatings on every air to glass surface, with special coatings also applied to all cemented surfaces, assuring you of superior light transmission (550nm transmits at approximately 96%, and overall transmission of all visible wavelengths measured at over 90%)

* Computer designed field stops placed at critical locations provide the highest degree of high contrast views

* Choose from 3.5mm, 5mm, 7mm, 10mm, 14mm, 20mm, 30mm and 40mm focal lengths. A full lineup of all your favorite focal lengths let you choose exactly the right eyepiece for low power viewing of Milky way star fields all the way to medium and high power planetary and lunar observing.

* The XW series conforms to a JIS 4 "daily use" waterproofing rating, assuring you that your eyepiece will give you maximum value over the years by remaining unaffected by the usual dewing and wetness that occur during your observation sessions (Note: this level does NOT assure waterproofing if the eyepiece is totally immersed in water).

* The WX series 3.5mm to 20mm eyepieces use a 1.25" size barrel and the XW30mm and XW40mm come with a 2 inch barrel.

* Height adjustable rotating eye caps let you easily place your eye at the exact location for comfortable viewing and perfect eye relief. Removing the eye cap exposes a 43mm / P0.75mm pitch male thread, for accessory attachment.

* All Pentax XW and XO eyepieces are threaded for standard 1.25" , or 2" size filters, depending on their barrel sizes.

Tough screw-on plastic bolt covers protect eyepieces from dust, grime, wetness and abrasion. Choose from 3 sizes that will fit all but the latest super sized eyepieces. Low cost, light weight and with tight threads that do not come undone unless you want them to. Cheap insurance that will keep your eyepieces individually protected, probably forever, with no maintenance. Will also accept labeling with an oil based felt pen. (Water resistant but not waterproof- not to be immersed in water with your precious eyepieces inside!). These bolt cases probably have a thousand other uses as well. How about using them to store nuts and bolts, coins, gold dust, trail mix or even your favorite coffee beans.... ; - )
