William Optics Binoviewer Package

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, SCT or Newtonian scope with the William Optics Binoviewer Package including:

• 1.25” Binoviewer with anti-marring compression rings
• 2x William Optics 20 mm WA 66 deg. eyepieces included (available optionally too)
• Barlow nosepiece (1.6x) for easier focusing with most telescopes! It can be mounted on other eyepieces too!
• Exclusive gift box.

Or go for the ROCK-BOTTOM price of the OTA version, if you already own a set of eyepieces! The price is very inviting, but the experience of three dimensional two-eyed viewing is even better! https://youtu.be/pGIw91gEkQ4
