I just bought a pair from the WO eBay shop but disappointedly it wouldn't focus with my WO Megrez 90 together with the essential WO dielectric star diagonal.
Not enough inward travel even using the supplied 1.6x barlow nose-piece. I do not expect a WO product wouldn't work on a WO scope. What is your experience? Does the WO binoviewer works with other WO scopes or the ED80?
