This stunning image of the Trifid Nebula was taken from Karnataka, India.

The Trifid Nebula (Messier 20 or NGC 6514) is a combination of emission nebula (the red area) and reflection nebula (the blue area) and dark nebula. [What Do You See? Strange Nebula Shapes (Photos)]
The Trifid Nebula is located about 5,200 light-years from Earth. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers). The Trifid takes its name from the dark dust bands that trisect its glowing heart. Astronomer Charles Messier first observed the Trifid Nebula in June 1764. Observations made about 60 years later revealed the dividing bands.
Unnikrishnan used a 11'' Schmidt Cassegrain Telescope, Canon 20D (Modified) with ISO 400 to combine 15 darks, 15 offset images.
