This telescope eyepiece is made in Japan by one of the top optical designers — It features lens elements manufactured to a higher degree of polish than competitive models. It's a 5-element design using modern high-refractive-index glasses resulting in flat-field images superior to those of simpler 4-element Plossl and Ortho designs. The wide 52° apparent field of view with 21mm eye relief is a pleasure to behold.
It's Ultra Multi-Coated, which means every air-to-glass lens surface is vacuum coated with multiple antireflective layers. Ultra Multi-Coating is the highest level of multi-coating there is. The coatings on this eyepiece dramatically improve both brightness and contrast, increasing the visibility of faint nebulas and planetary details. A low-reflection barrel design with blackened lens edges provides a significant increase in contrast and a reduction of stray reflections. Weight is 6 ounces..
