M25 (IC 4725) is a conspicuous cluster in the constellation Sagittarius
. For some unknown reason it was never deemed worthy of an NGC number, even though it is prominent even in the smallest binocular. The cluster is 2000 light years distant with a diameter of 19 light years and 90 million years of age.
