Please note that the black version shown in the photo above is William Optics' newest model released in late-2010. The white binoviewer you might see on other dealer sites - and even on William Optics' own website - is the older, discontinued version.
William Optics does it better and especially cheaper! Until today, you could choose only between high-end expensive binoviewers or monocular eyepiece observation. Today you can enjoy the benefits of BaK4 quality binoviewers in your refractor, Newtonian or SCT scope with a convenient package including:
• 1.25" Binoviewer with anti-marring compression rings
• 2x William Optics 20 mm WA 66 deg. eyepieces included
• 1.6x Barlow nosepiece for easier focusing with most telescopes! It can be mounted on other eyepieces too!
• Exclusive gift box.
The price is very inviting, but the experience of two-eye viewing is even better!
