For vertical centering, make the wrapping div set to display-table and the child to display:table-cell with vertical-align:middle. Horizontal centering can then simply be accomplished with text-align:center;

Try the CSS:

.header {
    height: 600px;
    display:table;
    width:100%;
}
.homeImageText {
    height:100%;
    display:table-cell;
    vertical-align:middle;
    text-align:center;
}
