AbstractWe have made a very deep photographic R band survey of a region of the Virgo Cluster by utilising digital stacking of scans of Tech Pan films taken on 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 M R ≃ −11 or about 5 × 10−5 L *) is very steep, with a power law slope α ≃ −2, supporting previous observational evidence at somewhat higher luminosities in other clusters.
