The Corona Australis
            molecular cloud complex sits low on the horizon even for those
            of us living in Arizona. Still, Its complex dusty brownish tint,
            two blue reflection nebula within and the blazing globular cluster
            in the background make this for a captivating composition. NGC6723-NCC6726-IC4812
            Nebulosities.
