 | | The stars, clusters and other objects of M24 form a portion of a spiral arm (the Sagittarius or Sagittarius-Carina arm) which fills a space of significant depth, at a distance of 10,000 to 16,000 light-years. |
 | | On about the western edge of M24, 12th-magnitude planetary nebula NGC 6567, of about 8 arc minutes diameter, can be found, a foreground object at a distance of about 4,000 light-years. |
 | | In the southern portion of M24, Delta Cephei variable WZ Sagittarii is found; this pulsating giant star varies in brightness between mag 7.45 and 8.53, and in spectral type between F8 and K1, in a period of 21.849708 days. |
