when needed. In some
Palomars, visual observers can resolve individual stars, while others look hazy. Palomar 9 (NGC 6717) is the easiest object to observe of the Palomar globulars, while Palomar 15 is regarded as the most difficult.

The
Palomar globulars have been discovered fairly late due to them being very faint, heavily obscured, remotely located or having few member stars. For this reason, these were discovered only with the enormous 48-inch

The
Palomar globulars can be observed and identified by amateur astronomers, however dark skies and high power are required. Astronomers have made reports on visual observations using 17.5 inch and larger
