Antares, M4, NGC6144 Globular Clusters
Orion 8" f/4 Astrograph

 
 This
            amazing field contains two well resolved globular clusters, and
            the red supergiant Antares on the left. I was not certain I could
            get M4 in the same shot, the field is very tight here! The main
            target of this shot however was the 9th magnitude globular NGC6144
            just above center. But the field is also filled with an orange
            glow - the largest orange colored reflection nebula in the sky.
            This is IC4606 and spans more than the 2.5 degree field of the
            8 inch.
