Thanks men I assume Greg, lots of blue stars? I can't make out any HII but that could just be a resolution issue?..generally speaking we would assume blue stars are likely to be rather cosmically young...unless, like is hypothesised in globular clusters (think Blue Stragglers), they have resulted from the merger of two big old stars...?
