Jscope 80-L 80mm F15 Refractor

The Jscope 80-L 80mm f/15 achromatic doublet is manufactured in Japan by Kubota Optical and distributed by Kasai Trading. 

This telescope excels at lunar and planetary observing and replicates the superb performance of previous classic Japanese-made 80mm F15 instruments from the likes of Nikon and Mizar. Modern lens polishing and multi-coating techniques bring this classic design into the 21st century.

It is equipped with a two-element air-spaced Fraunhofer-type achromatic 80mm F/15 objective lens manufactured by Kubota Optical in Japan.

HTM full multi-coating is applied to all four sides, achieving a high transmittance of over 99.8%.  Correction of chromatic and spherical aberrations is very good. In addition, Kubota Optical's careful and precise polishing technology has resulted in highly accurate and smooth optical surfaces, which provide the highest image quality.

Even at excessive magnifications of around 200-250x, there is no perceptible image breakdown, so you can enjoy sharp, high-contrast views with rich tones, especially on planetary surfaces. 

It is a premium objective lens that boasts ultimate performance and truly embodies the "Made in Japan' pride; the main reason Kasai decided to develop this product was because he was fascinated by the high potential of this lens. 

The Jscope 80-L includes a GSO-made 2" Crayford Focuser with 360-degree rotation with a 1:10 Micro Focuser.  The focuser provides a long back focus distance of 145mm and 80mm draw tube travel.

A 2" to 1.25" adaptor is included to enable the use of 1.25" accessories and eyepieces. The focuser is fitted with a generic Synta/Skywatcher/Vixen-style Finderscope shoe.

The optical tube is made from lightweight, robust aluminium alloy with a glossy white finish. Precisely positioned baffles are placed inside the telescope, and a black matte coating is carefully applied. This effectively blocks stray light and significantly enhances image contrast. The objective lens cell is made of thick-wall aluminium alloy to help maintain optical alignment. 

Also included are a set of Metal Tube Rings and a 335mm length Vixen-style mounting Dovetail Plate.

Most parts (except the focuser) are made in Japan, and all assembly is done in Japan.

For those looking for Japanese manufacturing and optical quality, we can highly recommend the Jscope 80-L
