NGC1866: New analysis from HST-WFPC2 observations of the inner regions
  We report new results on the LMC globular cluster NGC 1866 obtained by analyzing F555W and F814W images from WFPC2@HST. On the basis of the CMD we derive information on the cluster distance and constraints on stellar evolution theory. Evidence of mass segregation are found in the cluster core.
