Optical observation instrument

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 configured to record a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement, and
• a retaining apparatus, on which the optics unit is mounted, wherein the retaining apparatus comprises a retaining bracket, the retaining bracket being movably connected to the optics unit at
• both a distal end and a proximal end of the optics unit and, at each of the distal and the proximal end of the optics unit, the optics unit is movably connected to the retaining bracket with respective bearings, a first bearing of the respective bearings being located at the distal end of the optics unit and a second bearing of the respective bearings being located at the proximal end of the optics unit, the optics unit rotatable via the respective bearings around a center axis, the center axis between optical axes of the first and the second stereo channel and running through a center of the first and second bearings, wherein the retaining bracket comprises an operating device with a number of operating elements configured to control a retaining arm, to which the retaining apparatus is connectable.
