  About 2500 square degrees of sky south of declination -25 degrees and/or near
the galactic plane were surveyed for bright outer solar system objects. This
survey is one of the first large scale southern sky and galactic plane surveys
to detect dwarf planets and other bright Kuiper Belt objects in the
trans-Neptunian region. The survey was able to obtain a limiting R-band
magnitude of 21.6. In all, 18 outer solar system objects were detected,
including Pluto which was detected near the galactic center using optimal image
subtraction techniques to remove the high stellar density background. Fourteen
of the detections were previously unknown trans-Neptunian objects,
demonstrating that the southern sky had not been well-searched to date for
bright outer solar system objects. Assuming moderate albedos, several of the
new discoveries from this survey could be in hydrostatic equilibrium and thus
be considered dwarf planets. Combining this survey with previous surveys from
the northern hemisphere suggests that the Kuiper Belt is nearly complete to
around 21st magnitude in the R-band. All the main dynamical classes in the
Kuiper Belt are occupied by at least one dwarf planet sized object. The 3:2
Neptune resonance, which is the innermost well-populated Neptune resonance, has
several large objects while the main outer Neptune resonances such as the 5:3,
7:4, 2:1, and 5:2 do not appear have any large objects. This indicates that the
outer resonances are either significantly depleted in objects relative to the
3:2 resonance or have a significantly different assortment of objects than the
3:2 resonance. For the largest objects (H<4.5 mag), the scattered disk
population appears to have a few times more objects than the main Kuiper Belt
population, while the Sedna population could be several times more than that of
the main Kuiper Belt.
