As a prerequisite for cosmological studies using adaptive optics techniques,
we have begun to identify and characterize faint sources in the vicinity of
bright stars at high Galactic latitudes. The initial phase of this work has
been a program of imaging conducted with SOFI at the ESO NTT.
From observations of 42 southern fields evenly divided between the spring and
autumn skies, we have identified 391 additional stars and 1589 galaxies lying
at separations
from candidate guide stars
in the magnitude range
. When analyzed as
a “discrete deep field” with
area, our dataset
gives galaxy number counts that agree with those derived previously over the
range
. This consistency indicates that in the
aggregate, our fields should be suitable for future statistical studies. We
provide our source catalogue as a resource for users of large telescopes in
the southern hemisphere.
