The greatest advantage of a liquid mirror telescopic is its small cost, about 1% of a conventional mirror. This cuts down the cost of the entire telescope by 95%. Unfortunately, the mirror can only be pointed straight up. If it tilts from the Zenith , it loses its shape. The mirror's view changes as the Earth rotates and objects cannot be tracked. However, some types of Astronomical research are unaffected by these limitations, such as long-term sky surveys and Supernova searches. Since the Universe is Isotropic and Homogeneous , the investigation of its structure by Cosmologist s can also use liquid mirror telescopes. However, research is underway to develop telescopes that can be tilted. SOURCES
