Riding high in the south
            on warm summer evenings is this area in Corona Australis, the
            goal here was a composition which not only covered the globular
            NGC6723 on the upper right, but the dark nebula extensions perfectly
            aligned with the lower left corner. NGC6726 the blue reflection
            nebulosity is upper right of center, with dim red Herbig Haro
            objects near by forming new solar systems. Note the two butterfly
            like wings formed by the two loops of dark cloud on each side
            of NGC6726. This composition was also meant to carfully include
            those features as well.
