  We discriminated the extragalactic objects (galaxies and quasars) from stars
for Basle star fields, Plaut I, SA 54, and SA 82 by comparison of Basle fields
and APS POSS I finder charts. Their numbers are 187, 70, and 93 for Plaut I, SA
54, and SA 82, respectively. Most of these objects are apparently faint in V,
and they cause an overestimated local luminosity function for absolutely faint
magnitudes, M(V) > 5. This effect is more conspicious for the field Plaut I.
