Sextans A is a dwarf galaxy in our local cluster (outside the
milky way and indeed the member of the cluster furthest away form
us).
As a galaxy it contains millions of stars and you can not easily
identify the major stars in it.
However I do note that there appears to be a bright (orange
colored) star in Sextans A. This star is a member of our galaxy and
is not in Sextans A. I am afraid I do not know the designation/name
of this star, but one could look it up on star charts.
