The use of hydrostatic bearings for the support of the azimuth and elevation axes of telescopes offers a number of optical performance advantages. In addition to the benefits resulting from exceedingly low friction, the integration of hydrostatic bearings into the conceptual design of a telescope mount widens the range of geometric possibilities, particularly for larger telescopes. Mount stiffness and tracking accuracy are major advantages. This paper presents an overview of some of the design opportunities made possible by the use of hydrostatic bearings in addition to a discussion of the features and factor that are necessary for the their successful application.
