1. A hydrostatic bearing for supporting a telescope comprising:
a foot part supporting a load-carrying unit, a head part having a first surface adapted to receive an external load (W) and a second surface opposite to the first surface, a body part arranged in between the foot part and the head part, the body part forming a lower chamber and an upper chamber, the upper chamber being provided with an inlet for a pressurizing fluid, a lower member supportable by the load-carrying unit and arranged inside the lower chamber, the lower member providing a first end surface facing away from the load-carrying unit and a second end surface facing the load-carrying unit, an upper member controllable by the pressurizing fluid and arranged inside the upper chamber, the upper member providing a first end surface facing the second surface of the head part and a second end surface facing the first end surface of the lower member, wherein the lower member is controllably moveable along a central axis (A) between a retracted state, where the first end surface of the lower member is distanced from the second end surface of the upper member, and an extended state, and wherein the first end surface of the lower member is in contact with the second end surface of the upper member. |
