star field is very crowded with dim stars, we're far from Milky Way and
no light pollition was present at the location. But a yellowish glow is
visible below center. That's the Gegenschein, the faint glow of the
dust in the Solar System, at exactly the anti-solar direction. The
mouseover data were obtained with Unimap and I've measured an elliptical
dimension of about 20° x 15°. The background stars are mainly
from Aquarius, with the well known "Mercedes" asterism at the top.
