M19, is located across the border in the constellation of Ophiuchus and is nestled to the lower right of an arc of three wide binocular star pairs that include 26, 28, 31, and BF Ophiuchi, about 8 degrees east of Antares . These three pairs quickly become M19's distinctive landmark. M19 was one of Charles Messier's original discoveries, detected on June 5, 1764. While about 27,000 light years away from our Solar System, it is quite near to the Galactic Center, only about 4,600 light years away
and is visible as a small globular glow, with its ellipticity easily notable, shining about 7.15 magnitude. It is quite easily resolved.
A further globular cluster, NGC 6293, of mag 8.4 and 1.9' diameter is located 1.5 deg to the ESE, and another one, NGC 6284, of mag 9.5 and 1.5' diameter, 1.6 deg to the NNE. |
