M23
NGC 6494
This is a relatively young star cluster, probably no more than 200 million years old. Consisting primarily of blue stars, it has some similarities to the better known Pleiades, but is somewhat more developed and about four times further away from Earth.

Relative Galactic Position of M23
The star cluster known as Messier 23 lies almost exactly in the direction of our Galaxy's core. It is more than 2,000 light years nearer to the centre than the Sun.
