A stereoscopic viewing apparatus comprising:
- a pair of left and right spaced-apart ocular members, each ocular member comprising:
- a support arm with an aperture therethrough;
- and
- a surface defining an ocular window;
- a pair of left and right spaced-apart objective members, each objective member comprising:
- a support arm with an aperture therethrough;
- and
- a surface defining an objective window;
- and
- a common linkage defined by an alignment of the apertures of each ocular member and each objective member with a pin insertable therethrough, wherein the common linkage allows each ocular member and each objective member to be rotatably positionable with respect to one another in a plane that is perpendicular to both a plane containing each ocular member and a plane containing each objective member.
