Optical telescopes are powerful eyes for terrestrial and astronomical detection. Here we propose a new detection method with high efficiency, strong robustness and super precision, as an enhanced technique for optical telescopes in angular locating. In detail, our method requests only small number of incident single-photons, holds strong fault tolerance to any noise and improves the precision by magnitude orders comparing with current optical telescopes. Given these advantages, our method promises an important progress in remote sensing and astrometry, especially in locating the very dark object.
