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.
