Long-range optical device, in particular telescopic sight

Long-range optical device (1), in particular telescopic sight, comprising a reticle (6) that is adjustable in position and an associated device (7) for adjusting the reticle (6), characterised by

• a first magnetic element (10), in particular in the form of a ring magnet,
• a second magnetic element (11), in particular in the form of a bar magnet, which is motion-coupled to the reticle (6), wherein the second magnetic element (11) is mounted movably relative to the first magnetic element (10), wherein there can be formed or is formed in the first and in the second magnetic element (10, 11) in each case a variable magnetic characteristic value, in particular a variable magnetic field, as a function of the relative position between the first and the second magnetic element (10, 11),
• a detection unit (12), which is configured to detect a change in the magnetic characteristic value that can be formed or is formed in the first or the second magnetic element (10, 11), which change occurs in each case as a function of the relative position between the first and the second magnetic element (10, 11),
• a determination unit (13), which is configured to determine reticle position information describing the position of the reticle (6) based on a magnetic characteristic value of the first and/or second magnetic element (10, 11) detected by the detection unit (12) or based on a change in the magnetic characteristic value of the first and/or second magnetic element (10, 11) detected by the detection unit (12).
