CoRoT records simultaneously on its 4 detectors the brightness variations of 10 bright stars (with magnitudes between 6 and 9.5) for the sismology program and 12000 faint stars (with magnitudes between 11 and 16) for the exoplanet program.

These stars are chosen in order to reach the scientific objectives of the mission, relying on ground-based observations. However, the sky which can be observed by CoRoT is limited by the performance of the satellite and by the necessity of observing in the shade of the Sun.

The scientific qualities of the targets and the technical constraints define the "eyes of CoRoT" : two circles with a radius of 12 degrees, diametrically opposed on the sky, centered at the intersection of the galactic plane and the equatorial plane. One can be observed in winter and is located near the Orion and Monoceros constellations. The other is observable in summer and is located near the Eagle and Scutum constellations.
