Product Info

Manufacturer Description

Astro Hutech has resurrected the famed orthoscopic eyepiece series that was sold under the label of Kasai Trading Company of Japan for many years. These eyepieces are based on the classic Abbe Orthoscopic (3 + 1 element) design. The true Abbe Orthoscopic has long been recognized for its ability to deliver the highest resolution, contrast and light throughput of any modern eyepiece design.

The three cemented elements are hand-aligned by Japanese craftsmen. All components of this eyepiece, including all glass and other materials, are manufactured and assembled fully in Japan. 

Fully multicoated lenses provide clean, high-contrast images suitable for optimum planetary and lunar viewing. On-axis images are essentially perfect and the orthoscopic design ensures freedom from distortion. Contrast and throughput are maximized by its minimum of lens elements, coatings, and only 4 air-to-glass surfaces.

Features:

  • Fully multi-coated optics
  • 42 degree apparent field of view.
  • Eye relief: ~80% of focal length
  • Smooth-sided 1.25" eyepiece barrels
