It has three relatively bright nebulae The Lagoon Nebula (M 8) ,The Omega Nebula (M 17) both these object have an apparent magnitude of 6.0 and the Trifid Nebula (M 20) it has an apparent magnitude of 6.3. Together these three Nebulas are known as the Sagittarius Triplet.
The Lagoon Nebula (M 8)
The Omega Nebula (M 17)
The Trifid Nebula (M 20)
Apart from nebulas it also contains numerous star clusters.
M 22, apparent magnitude- 5.1
M 24, apparent magnitude-4.6, it also contains a faint cluster ngc 6603.
M 28, apparent magnitude- 7.66
Apparent from these and many more objects one can also see the limbs of the milky way galaxy which extends all the way to Scorpius. The picture below shows the exact location of the Messier objects.
