HST ACS CMDs of both fields of NGC 2366 and Ho I presented in ACS instrumental filters F555W and F814W, contoured by stellar density on the CMD. Regions of density less than 4 stars dmag−2 (﹩0.1\times 0.1﹩ mag bins) are plotted as points. Contours are spaced by factors of 2 to show the detailed structure of the CMDs.
