Scientific paper

Observations of three clusters were obtained with the CCD camera of the La Silla ESO in order to study the stability of stars in open clusters. For the brightest stars, precisions per observation in the r filter of about 3 mmag are obtained. No Delta Scuti stars with amplitudes above 0.03 mag were found in the young clusters Melotte 105 and NGC 4755, while 12 Delta Scuti stars have been found in the old cluster NGC 2660. The results suggest the presence of a small group of variable Ap stars in Melotte 105, along with very active late-type stars in NGC 4755.
