Messier 72 is a relatively dim cluster just
about 3 degrees away from the Saturn Nebula (NGC 7009) in the western part
of Aquarius. At about magnitude
9.3, it is not difficult to see in even small telescopes, but resolving its 15th magnitude stars requires a fairly large aperture. Through my 18-inch telescope at 175x, some of its stars can be resolved. The cluster is about 56,000 light years
away, a distance that is about half the diameter of our galaxy.
