Abstract We use a combination of data acquired with the Advanced Camera for Survey on board the Hubble Space Telescope and the Large Binocular Camera (LBC-blue) mounted on the Large Binocular Telescope to sample the main sequence (MS) stars of the globular cluster (GC) NGC 5466 in the mass range from 0.3 to 0.8 solar masses. We derive the cluster's Luminosity Function (LF) in several radial regions, from the center of the cluster out to the tidal radius. (...) We compare the radial variation of ? from the center out to 5 core radii (rc) in NGC 5466 and the GC M10 (...) NGC 5466 is dynamically younger than M10, with two-body relaxation processes only recently starting to shape the distribution of MS stars. This result fully agrees with the conclusion obtained in our previous works on the radial distribution of blue straggler stars, further confirming that this can be used as an efficient clock to measure the dynamical age of stellar systems.
