Optical system for imaging an object

An optical system for imaging an object has at least a first objective, at least a first image stabilizing unit and at least a first eyepiece, wherein, as seen in the direction of the first eyepiece from the first objective, the first objective is arranged first along a first optical axis, then followed by the first image stabilizing unit and then followed by the first eyepiece. The first image stabilizing unit is rotatably mounted in cardan-joint fashion about a first hinge point, and the first hinge point is arranged between the first objective and the first eyepiece. The optical system is distinguished by virtue of the fact that the first image stabilizing unit comprises a first lens unit and at least a further optical element, wherein the first lens unit and the optical element are arranged such that the first lens unit is, together with the optical element, rotatably mounted in cardan-joint fashion about the first hinge point.
