The Great Hercules Globular Cluster - M13
Orion 8" f/4 Astrograph

 
 There
            are few globular clusters that compare with the concentration
            and brilliance of this object. Settled in a field of colorful
            stars in the Hercules Milkyway, you can also see NGC6207 a small
            12.2 magnitude inclined spiral to the lower left. But look more
            closely at the larger image, about half way in between M13 and
            NGC6207 is a faint edge on galaxy IC4617, a 15.5 magnitude test
            for 12 inch telescopes visually.
