This in a very nice sight in binoculars. It's located below and to the left of M17, the swan. It's bright at magnitude 4.6, nice with several prominent members, and big at about 30 arc minutes in extent. Because of it's size, it's a bit big for a medium to large telescope, and the view looses it's context. Never-the-less it has a fine group of distinctively brighter central stars surrounded by a nice bed of the Milky Way's background stars. M25 has about 80 members which range around 90 million years old. They are about 2000 light years away spanning about 17 light years in extent.
