M15 is one of the
finer globular star clusters. Located in Pegasus about 4o
to the northwest of Epsilon Peg, M15 appears as a 7th magnitude
fuzzy star in binoculars. Small telescopes will resolve many of the
stars, but it takes a large aperture and a night of good seeing to
resolve stars all the way to the rich core.
This cluster contains
hundreds of thousands of stars within a diameter of 80 light years.
In his "Celestial
Handbook", Burnham said, "M15 is one of the richer and
more compact globulars, remarkable for the intense brilliance of its
central core where the countless stars seemingly crowd together into
a blazing nuclear mass..."
