3. The device as claimed in claim 2 , wherein the ball joint comprises bearing surfaces on the eyepiece-side end of the lens tube and bearing surfaces in the bearing housing, wherein the bearing surfaces are formed by ball areas and wherein the ball areas are aligned to be at least approximately perpendicular to an optical axis of the observation beam path.

4. The device as claimed in claim 3 , wherein bearing surfaces in an eyepiece-side area relative to a pivot point of the bearing housing have a first middle radius r 1 relative to the optical axis of the observation beam path and a first ball radius R 1 and bearing surfaces in an object-side area relative to the pivot point of the bearing housing have a second middle radius r 2 relative to the optical axis of the observation beam path and a second ball radius R 2 and a ratio between the second middle radius r 2 and the second ball radius R 2 is smaller than a ratio between the first middle radius r 1 and the first ball radius R 1 .

5. The device as claimed in claim 2 , wherein a focal length of the front objective lens system is greater than a distance D of a pivot point of the bearing housing from the front objective lens system.

6. The device as claimed in claim 1 , comprising an opto-electronic display device for displaying variable data or a target mark, wherein a display beam path of the display device runs at least partly in the observation beam path for displaying a remote object, wherein the display device comprises an Liquid Crystal on Silicon (LCoS) display.

7. The device as claimed in claim 6 , wherein the display device comprises an illuminating prism and a display prism, wherein a section of a transition of the display beam path is localized into the observation beam path in the display prism.

8. The device as claimed in claim 7 , wherein the display prism is arranged between the lens reversing system and the eyepiece.

9. The device as claimed in claim 7 , wherein the display device comprises an illuminating prism and a display prism, and the device comprises a prism reversing system arranged between the objective and the eyepiece, wherein a section of a transition of the display beam path is localized into the observation beam path on a prism of the prism reversing system.

10. The device as claimed in claim 7 , wherein the illuminating prism and the display prism are joined together by adhesion.

11. The device as claimed in claim 7 , wherein between the illuminating prism and the LCoS display a wave plate is arranged, wherein the wave plate is formed by a λ/4 plate.

12. The device as claimed in claim 11 , wherein the LCoS display, and the wave plate and the wave plate and the illuminating prism are joined together respectively by adhesion.

13. The device as claimed in claim 6 , wherein it comprises a zoom sensor for detecting a value of a set enlargement.

14. The device as claimed in claim 13 , wherein the zoom sensor comprises a foil potentiometer and a trigger connected to a zoom adjusting ring.

15. The device as claimed in claim 6 , wherein the LCoS display is connected to a display control, wherein the display control comprises a Field Programmable Gate Array (FPGA).

16. The device as claimed in claim 1 , further comprising a rangefinder with a laser transmitter and a laser receiver.

17. The device as claimed in claim 1 , further comprising an inclination sensor.

18. The device as claimed in claim 1 , further comprising a main control unit with a ballistics computer.

19. The device as claimed in claim 18 , wherein the main control unit is designed for generating image information data for representing a variable graticule on a Liquid Crystal on Silicon (LCoS) display.
