  Globular star cluster M62   (Site not responding. Last check: 2007-10-22)
The globular star cluster Messier 62 in Ophiuchus, shown in an R-band CCD image obtained with the UA 16-inch telescope.
M62 appears on the southern tip of Ophiuchus; against the star patterns it looks as if it ought to belong to Scorpius.
This image uses logarithmic intensity scaling to bring out both the central blaze of stars in the cluster and the very rich general field of stars toward the galactic bulge.

M62 is a tine globular cluster positioned almost on the boundary line between Scorpius and Ophiuchus.
Another globular cluster of M19, lying about 4 degrees north of M62, has almost same declination with that of Antares, so you can find M62 by tracing from Antares via M19 easily.

 Globular Star Clusters - Information and Observations
Globular clusters are the senior citizens of our galaxy - they contain suns at least 12 billion years old.
Summer nights are the best time to start hunting for globular clusters, almost one third of them are to be found in the summer constellation of Sagittarius.
For your first observation of a globular cluster choose M13, the brightest cluster visible from the northern sky, teetering on the edge of naked-eye visibility and appearing as a small, hazy glow in binoculars.

 Star Clusters - Globular
Globular clusters are not formed within the galaxy structure, but usually large numbers of them form a halo around the main galactic structure.
Globular clusters usually require a larger telescope and higher magnification to observe to best effect, although the larger and closer ones can be spectacular in small instruments.
Stellar concentration is average for a globular cluster and it is one of the metal-richest globulars.

 characteristics of globular clusters Text - Physics Forums Library
Globular clusters, on the other hand, are very old, large (as large 106 stars), and live in the galactic halo.
Globular cluster stars have typical velocities around 5 km/s, leading to proper motions of about 0.2 mas/yr at the typical distance of 5 kpc.
The apparent convergence of the proper motion vectors is due to overall motion of the cluster relative to the sun.

 Messier 62 - Wikipedia, the free encyclopedia
Messier 62 (also known as M62 or NGC 6266) is a globular cluster in the constellation Ophiuchus.
M62 is at a distance of about 22,500 light-years from Earth and measures some 100 light-years across.
The globular also contains a number of x-ray sources, thought to be close binary star systems, and millisecond pulsars in binary systems.

M62 is one of the most irregular shaped globular clusters, as was first reported by Herschel.
This deformation may be a result of the fact that M62 is one of the closest of Messier's globulars to the Galactic center (only about 6100 light years), so that it is deformed by tidal forces.
There are more intrinsic differences between these two globular clusters: M62 has the large number of 89 known variables (number of 1973 !), most of them of RR Lyrae type, while M19 has only 4.

M62 is one of the most irregularly shaped globular clusters, as was first reported by Herschel.
