Messier 24 (IC 4715) - the Sagittarius Star Cloud; distance 10,000 light years from Earth and about 600 light years wide.

The Barnard Dark Nebulae B92 (middle right) & B93 (middle) comprise dense obscuring dust blocking light from more distant stars behind them.

The small star cluster in the lower middle is NGC 6603.

M18 is on top middle left margin.

The general pinkish-reddish hue is the larger emission nebula known as Sharpless 41.
