It approximately 2,150 light years from Earth and has an apparent magnitude of 6.9. The cluster has a radius of 15 to 20 light years and contains 176 confirmed members (source: Messier Objects).
This is one of the few Messier Objects that I have left that I can actually image from my yard. This object, being in Sagittarius, is in the direction of the center of the Milky Way and, therefore, has lots of gas, dust, nebulosity, and stars. The cloudiness appears faintly in my image.
This brings me up to 93 Messier Objects captured so far...
