On the basis of astrophotographic tests and zonal interferometry of the surface, it is shown that a parabolic mirror formed by rotating a reflecting liquid in a system of vessels floating freely in one another satisfies the demands imposed on the objectives of optical telescopes. With a stationary outer vessel (foundation pit) this scheme is distinguished by simplicity of realization, it eliminates factors distorting the shape of the reflecting surface, and practically removes the limits on the mirror diameter, providing the prospect of creating large zenith telescopes with liquid objectives as a basis.
