Deep Images of Bright Galaxiesng magnitudes, especially for extended objects. This limit can be extended even further by applying special photographic techniques to the plates and combining the enhanced information from several deep plates. This allows us to reach a limiting (B) surface brightness of about 28 B mag aresec., whic

A Deep Tech Pan Survey of Dwarf Spheroidal Galaxies in Virgo the U.K. Schmidt Telescope. The objects we detect have the same physical sizes and surface brightnesses as Local Group dwarf spheroidal galaxies. The luminosity function of these extremely low luminosity galaxies (down to .. ≃ −11 or about 5 × 10...) is very steep, with a power law slope . ≃ −2, su

Surveys with a 4m Liquid Mirror Telescope is its very low cost, is particularly well suited for the search and study of gravitational lenses, type Ia supernovae, faint nearby red, brown and white dwarfs, halo stars with high proper motions and, more generally, all variable phenomena like quasars, variable stars, micro-lensing effects, etc.
