Descripción
We present deep and accurate Near-Infrared (NIR) photometry of the
Galactic Globular Cluster (GC) ω Cen. Data were collected using
the Multi-Conjugate Adaptive Optics Demonstrator (MAD) on VLT (ESO). The
unprecedented quality of the images provided the opportunity to perform
accurate photometry in the central crowded regions. Preliminary results
indicate that the spread in age among the different stellar populations
in ω Cen is limited.
