One of the valedictory projects undertaken by WFPC2 was a survey of UV bright objects in 30 globular clusters. Eventually these results will be combined with similar results obtained by our group for 15 clusters. For most of these clusters observations were obtained with 4 or more filters. For a subset of clusters we also have observations from GALEX which will allow us see if the sort radial variations previously found in blue straggler stars (BSS) also exists in the hottest stellar populations. Here we present the case of NGC 6229. The data set has been obtained by combining high-resolution (HST/WFPC2 and ACS) and wide-field space (GALEX) observations and ground-based (MegaCam-CFHT) images. The photometric sample covers the entire cluster extension from the very central regions up to the tidal radius and beyond. We determine the radial density profile and we study the BSS population and its radial distribution.
