Refractor 135mm F/6.7 Binotelescope


This is our first product designed for using our eyes in a natural way. Built around two single optical tube assemblies, shortened to accommodate the 3-inch fusion image system, made in Japan (Matsumoto – EMS).
By using the maximum practical aperture for the focusers and EMS system, the bino will allow using 2″ eyepieces without any vignetting of the light cone.
It has the light gathering power of a 190-mm unobstructed objective while the use of our eyes in a natural way increases perceived resolution. Highly recommended for visual astronomy.
