A sighting mirror, especially for sighting instruments, includes a stabilizing device for stabilizing the mirror position independently of the operating conditions, once the mirror has been trained on a target. A substantial accuracy in the stabilizing is achieved by providing a rough mirror frame stabilization and a fine mirror stabilization independently of the mirror frame stabilization. The fine stabilization is achieved by piezoelectric elements interposed between the mirror frame and the mirror which is pivotally attached to the mirror frame. A gyro provides electrical first control signals for the rough adjustment of the mirror frame, for example by a frame drive motor. The gyro also provides second control signals for the fine adjustment of the mirror by the piezoelectric elements. Movement translation may increase the effect of the piezoelectric elements.
