Paper Abstract

Mercury liquid mirror telescopes work. This ia by now a well-established fact. However they suffer from a major limitation: they cannot be tilted. We have recently proposed that liquid mirrors can be tilted by several tens of degrees, provided one can develop a high-viscosity liquid having a high coefficient of reflectivity. The technology promises inexpensive large telescopes. We present the concept and some of the ongoing work.
