NGC 6544 is located in the western part of the constellation of Sagittarius, on the edge of a rich star field. Easy to find since is just 50' towards the southeast of the well known Lagoon Nebula. It can also be noted from dark skies with 10 x 50 mm binoculars as a small white spot like a misty star.
