Deep Ecliptic Survey


The Deep Ecliptic Survey obtained deep images within a strip 13-degrees wide covering the full circumference of the ecliptic, using the Mosaic CCD cameras on the KPNO Mayall and CTIO Blanco 4-m telescopes. The primary goal was to identify faint Kuiper Belt Objects (KBOs) with the goal of mapping out the structure and population of the Kuiper Belt. To detect KBOs, each field was imaged twice within a single night. Exposures are typically 4 min. Data products include the reduced and calibrated survey images.
