Aims.We carry out and analyze new multi-color photometry of the Galactic globular cluster (GC) M 75 in and focus on the brighter sequences of the color–magnitude diagram (CMD), with particular emphasis on their location in U-based CMD. Specifically, we study the level both of the horizontal (HB) and red giant branches (RGB) relative to the main-sequence turnoff (TO) in the U magnitude.
