Abstract

Four probable Ap members of the open cluster NGC 6475, were investigated through detailed spectrum synthesis. Cluster membership was confirmed for all four stars, however chemical abundance analysis shows that only three are truly Ap. Derived $v \sin i$  values and chemical abundances for 20 elements ranging form C to Eu are presented.
