Scientific paper
Borra (1982) has argued that it is scientifically useful and should be technically feasible to build very large optical telescopes (diameters over 15 meters) having as primary mirror a rotating container filled with mercury. The authors report here the results of optical tests on prototype liquid mirrors. Knife-edge and Hartmann tests, as well as direct imagery, show that optical quality surfaces are attained. The largest mirror produced has a diameter of 1.65-m but the authors tested thoroughly only a 1-m diameter mirror.
