  We employ the recently installed near infrared Multi-Conjugate Adaptive
optics demonstrator (MAD) to determine basic properties of a newly identified,
old and distant, Galactic open cluster (FSR1415). The MAD facility remarkably
approaches the diffraction limit, reaching a resolution of 0.07 arcsec (in K),
that is also uniform in a field of ~1.8 arcmin in diameter.
  The MAD facility provides photometry that is 50% complete at K~19. This
corresponds to about ~2.5 mag below the cluster main sequence turn-off. This
high quality data set allows us to derive an accurate heliocentric distance of
~8.6 kpc, a metallicity close to solar, and an age of ~2.5 Gyr. On the other
hand, the deepness of the data allow us to reconstruct (completeness-corrected)
mass functions indicating a relatively massive cluster, with a flat core MF.
The VLT/MAD capabilities will therefore provide fundamental data in
identifying/analyzing other faint and distant open clusters in the Galaxy III
and IV quadrants.
