Japanese made Masuyama eyepieces are available now!

After nearly 30 years, Masuyama eyepieces are back in production. Designed by the renowned optician Dr Masuyama and updated with five-element modified Plossl design, modern glass and multi-coatings. Among other things, Dr. Masuyama designed an eyepiece with a focal length of 100 mm, which was used on the historic 60-inch telescope at Mount Wilson Observatory in California. We are pleased to offer you these legendary eyepieces with the latest glass and coating technology.

The removable rubber grips makes these ideal for use in binoviewers.
