1. A method for adjusting and/or calibrating a medical microscope, the following being implemented for at least one observer beam path of the medical microscope:
capturing respective image representations of an object at different magnification levels of a zoom optical unit in the at least one observer beam path by means of a capture device in the at least one observer beam path, and
determining a zoom center using the captured image representations as a starting point, and
i) capturing respective further image representations of the object at different axis positions of at least one linear or rotational movement axis of the medical microscope, a rotation of the capture device relative to the at least one linear or rotational movement axis being determined using the captured further image representations as a starting point, and/or
ii) capturing respective further image representations of the object in different focal planes and/or at different working distances in the case of an off-centered imaging optical unit of the medical microscope, a rotation of the capture device being determined using the captured further image representations as a starting point, and
determining a reference marking using the determined zoom center and the determined rotation as a starting point and being provided for adjustment and/or calibration purposes.
