M55

Messier 55 (also known as M55 or NGC 6809) is a globular cluster in the south of the constellation Sagittarius. It was discovered by Nicolas Louis de Lacaille on 1752 while observing from what today is South Africa. Starting in 1754, Charles Messier made several attempts to find this object from Paris but its low declination meant from there it rises daily very little above the horizon, hampering observation. He observed and catalogued it in 1778. The cluster can be seen with 50 mm binoculars; resolving individual stars needs a medium-sized telescope.It is about 17,600 light-years away from Earth.
