Description
We present the preliminary results of the ground-based (MegaCam@ CFHT)
and space-based (ACS@HST) photometry for the Galactic globular cluster
M71. By comparing data and theory, we found that the age
(11.0±1.5Gyr) of M71 agrees well with the bulk of the more metal
poor globular clusters.
