Abstract

The advantages of using a liquid mirror in a lunar telescope are summarized. Interferometric measurements of a 1.5-m diameter liquid mirror are presented which show that liquid mirrors can have the very high optical quality required of a lunar telescope. Some of the liquid metals that could be used are discussed.
