Claim:
1. A long-range optical device, comprising at least one optical channel having a housing and an arrangement of optical elements, at least one of the optical elements being movable relative to the housing for image stabilization in the event of perturbing movements of the housing, a carrier movable relative to the housing, a stabilization system for the at least one movable optical element, the stabilization system having an eddy current damper for damping movements of the at least one movable element, the eddy current damper in the event of a displacement of the at least one movable optical element generating a restoring force proportional to the displacement velocity of the at least one movable optical element, the restoring force being dependent on an amplitude of the displacement of the at least one movable optical element, the eddy current damper having a magnet system and an eddy current carrier interacting with the magnet system, wherein the magnet system has at least one magnet extending radially with respect to a longitudinal axis of the optical channel, and the at least one magnet has at least one surface which is curved, in such a way that a distance from the plate to the at least one magnet varies over the plate.
