The William Optics Binoviewers give you a completely new viewing experience. You look with both eyes at the same time, making observation feel much more comfortable and natural. This makes long sessions less tiring and gives a better sense of depth in planetary and lunar observations.

This set is ideal for refractors, Newtons or Schmidt-Cassegrains. The included BAK4 prisms and fully multi-coated optics ensure bright, sharp images. The compression rings hold everything firmly in place, keeping your image stable.
The binoviewer comes with two 20 mm eyepieces (66° field of view) and a 1.6× Barlow lens. So you can easily focus and use different magnifications without additional accessories. The optical path is 100 mm, suitable for most telescopes.
You can add additional eyepieces to expand your viewing experience. For best results, we recommend high-quality eyepieces such as Omegon LE. All in all, this makes a complete set for serious visual observation with more comfort and detail.
