Attention is drawn to the existence of three axes equatorial mounts for ground based observing. The additional third axis with respect to a conventional two axes equatorial or altitude-azimuth mount allows the position angle to be set at almost any predetermined value when observing close to the zenith. In addition to that, the quasi-total absence of cantilever parts is an asset for interferometric stability. The SIMURIS strategy uses some breadboard for fine structure imaging on the ground in the visible domain as an intermediate step between laboratory developments and flight operations; tactics for solar or stellar interferometric observations are investigated.
