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

      5.0 A solid performer

      Pros:

      Strong Construction,Easy to Use,Quality Lenses,Accurate,Compact

      Cons:

      Comments:

      Orthoscopic performance. Bright (i.e. no visible hue). Solid and weighty yet small and suitable for grab-and-go. Beautifully complements my 24 Pan. Ideal for medium power DSO and planetary work. If you are not worried about AFOV, you'll be pleased to have got this one.

      I use this in my 8'' sct and the veiws of Jupiters bands and great spot have extreamly good detail. You can see Saturn's Cassini division with great detail, and some faint galaxies. Love this product. Best ortho since Zeiss.

      5.0 Excellent Ortho

      Pros:

      Quality Lenses,Strong Construction

      Cons:

      Comments:

      Superb Ortho which is indistinguishable from my 9mm Baader Genuine Ortho, no longer made. The Baader Genuine Ortho has been noted indistinguishable from the much vaunted Zeiss Abbe Ortho, also no longer made.
