The well-known astrophotographer Roberto Colombari had an APOD with his picture of Messier 24 (M24) on June 29, 2018. Colombari is an expert on RGB photography, which is something I love, of course. I find Roberto Colombari's APOD easier to "read" than today's APOD.
There is a great picture by BQ Octantis at Cloudy Nights that helps you put M24 into perspective:
Star clouds, clusters and notable stars in M24.

The Large Sagittarius Star Cloud is the brightest part of the Milky Way. There is an opening in the thick central dust lane here that allows us to see the bright yellow bulge of the Milky Way.
M24 is a much smaller star cloud. Note, however, its blue color. The color is due to the fact that there are many young stars in M24. By contrast, virtually all the hundreds of millions (or billions?) of stars in the Large Sagittarius are old and yellow.
