The William Optics Binoviewers<\/strong> 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.<\/p>\n\n\n\n

\"William<\/figure>\n\n\n\n

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.<\/p>\n\n\n\n

The binoviewer comes with two 20 mm eyepieces (66\u00b0 field of view) and a 1.6\u00d7 Barlow lens. So you can easily focus and use different magnifications without additional accessories. The optical path is 100 mm, suitable for most telescopes.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n
