OCKS: OGLE Carnegie Kuiper Belt Survey

OCKS is a Southern sky survey searching for Kuiper Belt objects and dwarf planets. This is a common project of the OGLE collaboration and the Department of the Terrestrial Magnetism of the Carnegie Institution of Washington.

Observations are carried out with the 1.3 m Warsaw Telescope at Las Campanas Observatory, Chile, equipped with the 32-chip, 256 Mpixel mosaic camera covering 1.5 square degrees in the sky with scale of 0.26 arcsec/pixel.
