Levenhuk Plössl eyepiece with a focal length of 4 mm and a 50-deg field of view is one of the most popular models among stargazers. Such eyepieces perform best during visual observations, where image geometry and clarity is more important than field of view and contrast.
Two high-quality achromatic lenses of the eyepiece are fully multi-coated to produce exceptionally bright views of the observed part of the celestial sphere.
Levenhuk Plössl 4 mm has an eye relief of 3.5 mm and a soft rubber eyecup, which provide for additional comfort during observations. The barrel is threaded to accept filters.
