The telescope is provided with two mutually perpendicular rotation axes (K-K, V-V) and an optical axis (Z-Z) perpendicular to one rotation axis (K-K). The optical axis (Z-Z) is perpendicular to the rotation axis (K-K) and the latter is perpendicular to the rotation axis (V-V). Rotation about the rotation axis (K-K) pivots the optical axis (Z-Z) in that plane which also contains the rotation axis (V-V). An aiming marker carrier is arranged at least approximately in a vertical plane which contains the other rotation axis (V-V) as well as the optical axis (Z-Z). An aiming marker (Zi) mounted on the aiming marker carrier is arranged on the optical axis (Z-Z). The virtual image (Zi') of the aiming marker (Zi) is preferably situated at the common point of intersection of the optical axis (Z-Z) and the rotation axes (K-K, V-V) when viewing the aiming marker (Zi) from outside through the telescope lens. The aiming marker carrier can be constructed to be transparent and the aiming marker to be less light-transmitting, or the aiming marker can be constructed to be transparent and the aiming marker carrier to be less light-transmitting. The aiming marker carrier can be mounted fixed on the telescope or in a pivoting fashion in the telescope. The aiming marker can be illuminated by illuminating devices. The device facilitates the alignment of devices with one another by means of telescopes mounted thereon. The telescopes are orientated relative to one another after in each case sighting once with both instruments in both positions and setting the position determined. <IMAGE>
