Product description

Masuyama eyepieces are known for their clear and high contrast imaging and velvet black background. The good contrast of these high-end eyepieces is achieved with a special cut, internal diaphragms and the best possible internal blackening. Due to the elaborate lens design, the eyepieces get by with only 5 elements, with good correction at the same time.

Despite the large field of view, the short focal length Masuyama eyepieces are highly recommended for planetary and double star observation. At the same time, the eyepieces are of course very nice overview eyepieces for deep-sky observation. The long focal length eyepieces are well suited for finding and observing large area deep sky objects.

The eyepieces were developed by renowned optician Dr. Masuyama. 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.
