An aiming apparatus, for example, for aiming at a target, has an aiming head (11), an ocular unit (13) and a display section (22) between the aiming head and the ocular unit. The display section (22) has, for example, a thermal imager (24) and a cathode ray tube (26, 27) operated by the thermal imager for displaying a thermal image received through a beam splitter. The aiming head (11) and the ocular unit include the required optical elements and an ocular (19). Each section has its respective housing. The housing of the aiming head (11') is rotably interconnected for rotation about its normally vertical axis (30) at least with the thermal imager (24) rotatable about its horizontal axis (23) in a corresponding synchronous rotation, whereby the screen (27) and any image on the screen of the cathode ray tube (26) retain their relationship unchanged even if the aiming head is rotated by a pointer through an azimuth angle. This is so because the aiming head and the thermal imager rotate with the same angles.
