1. An optical observation instrument comprising:
an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path, the optics unit configured for recording a stereo image of an object field with the at least one electronic image recorder, and wherein the first and the second beam paths extend through the objective arrangement, and
a retaining apparatus, on which the optics unit is mounted, the optics unit rotatable about the objective arrangement, wherein the retaining apparatus comprises a retaining bracket, which a first axis of rotation, the first axis of rotation at least approximately corresponding to an axis of the objective arrangement, wherein the retaining apparatus comprises a retaining bracket, which engages over the optics units, which is arranged inside a housing, and on which the optics unit is mounted to be rotatable about the first axis of rotation, wherein an optical deflection element is retained at an object-side end of the retaining bracket, and wherein the optical observation instrument has a viewing direction that is angled in relation to the axis of the objective arrangement and comprises the optical deflection element, arranged on an object-side of the objective arrangement, and configured to deflect the first and the second beam paths into the objective arrangement.
