Abstract
The mirror support arrangement of the invention takes up force components in the azimuthal axis of the primary mirror of a telescope as well as moments about the mirror axis at the location where they are developed. Although forces of this kind cannot occur in earthbound telescopes, a rapid rotation about several axes can generate such moments especially when the mirror is driven in a mount having three orthogonal drive axes. A hydraulic lateral support acts at several points on the rear side of the mirror. This support is realized in the form of a V-support. The lateral V-support can take up all lateral forces within the V-angle.
