The William Optics 1.25-inch Binoviewer gives you quality and affordability, the best of both worlds! Enjoy the benefits of a BaK-4 quality binoviewer in your refractor, Newtonian or SCT scope!

The WO Binoviewers offer exceptional quality and attention to detail. These telescope binocular viewers are standard with an anodized aluminum finish to compliment any telescope and the anti-marring eyepiece-compression-ring system guarantees stability and security. Large chromed thumbscrews hold the William Optics Binoviewer to your focuser and the system works with a 1.25-inch or 2-inch star diagonal for added viewing comfort. Its 4-inch optical path means you'll have less trouble getting these binoviewers to come to focus with your telescope and the high-quality multi-coatings mean brighter, more contrast-enhanced views! William Optics tests their binoviewers before they leave the manufacturer for collimation and offers a two-year warranty against product defects. Please keep in mind that damage or loss of collimation from dropping or rough handling of binoviewers is not covered under warranty.
