An operating microscope including an optical unit for forming an image of an object plane in oculars of the microscope, an optoelectronic image receiver coupled to the microscope and optics to form images, of objects placed in a region between a front objective of the microscope and an object plane of the microscope, on the optoelectronic image receiver. The microscope has a magnification factor of the optics to form images, and a system to detect optical markings forming a markings pattern placed on a surgical instrument or an object placed in the region between the front objective of the microscope and the object plane of the microscope. The system calculates a geometrical position and orientation of the markings pattern in relation to the optoelectronic image receiver, relative to the microscope.
