This is the second Asiago blue objects field studied to determine the physical nature of ultraviolet excess objects (UVX) at high galactic latitudes using low dispersion objective prism plates. As the first of this series ( Abati 1982 )this work has a double aim:

  1. 1. to determine the proportions in the component populations of UVX objects selected by the two-colour method on Schmidt telescope plates;

  2. 2. to determine the surface density of quasars down to a limiting magnitude m = 18 mag.
