M19: Globular Star Cluster (Ophiuchus) RA: 17h 02.6m / DEC: -26° 16'.1
Instrument: 10-inch Starfinder

M19 is another of the fine globular star clusters scattered throughout Ophiuchus. You'll find M19 adrift in the far southeastern corner of the Coffin, about three degrees west of 4.3 magnitude 36 Ophiuchi. This 6.8 magnitude globular is a wonderful sight in my 10-inch. The drawing, made at 129X, shows an irregular core about 3'x2' in size. This core is populated by several 13th and 14th magnitude stars. The surrounding glow extends to a diameter of 10' with a line of four 11th magnitude stars along the west-northwest border. A pair of 12th and 13th magnitude stars form a nice double just a few arc minutes east of the globular.
