1. A long-range optical device comprising:
at least one sight channel;
an image capturing channel; and
a processing unit,
wherein the image capturing channel comprises a camera module with an autofocus function,
wherein the sight channel comprises a first focusing lens and a sensor connected to the processing unit for the detection of a movement of the first focusing lens,
wherein the processing unit is program controlled to trigger the autofocus function of the camera module when detecting a termination of a movement of the first focusing lens, and
wherein in the sight channel a first beam path is formed by a first objective, the first focusing lens, an erecting system and a first eyepiece, and wherein in the image capturing channel a second beam path is formed by a second objective, a second focusing lens, and a second lens group, and the camera module, wherein in the first beam path of the sight channel a reference image plane is determined by a reticle or by an image reproduced by projection optics, wherein the first eyepiece of the sight channel is displaceable by means of a second focusing unit for focusing on the reference image plane.
