A globular cluster which may be visible to eagle-eyed observers
with the naked eye under very dark skies.
This impressive cluster is easily seen with binoculars as a round fuzzy patch.
M15 has a bright compressed core surrounded by a faint halo of stars.
With a larger instrument more stars become visible in the outer periphery
with some brighter members resolved in the center.
M15 is one of only a handful of globular clusters known to contain a planetary nebula.
