What
            to shoot when the seeing is not so great? Rich open clusters.
            The slightly larger stars will show the star colors better, and
            as you see here, there is plenty of blues and golds. The stars
            in this cluster are also quite brilliant - and many left saturated
            blooms all over. Still, well worth the shot!
