This visual system pairs two fluorite apochromatic refractors so each eye receives its own optical path. The oil-spaced triplet objectives are combined with independent FeatherTouch focusers and Matsumoto image-erecting units.
Observing configuration
Matched eyepieces set the magnification. The documented mounting package includes a precision support, rings and rail, with a wooden transport crate. Allow for the complete binocular assembly when choosing a mount.
The 3-inch mounting rail is not an assertion about saddle compatibility or bolt pattern. EMS is an erecting mirror system; catalogue use of 'prism' is not repeated as an optical construction claim.
