William Optics does it better and especially cheaper! Until today, you
could only choose between so-called 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 by
choosing William Optics Binoviewer
Optional 2x barlow/corrector 1.25" nosepiece and a 1.25" extender
nosepiece are available separately for customers with special focusing
needs. You can also purchase eyepieces for your binoviewer through our
online shop. We recommend 20mm to 15mm focal lengths. You can choose
between WA, SWA and UWA eyepieces.
