Comments: The seeing got worst when taking the subexposures for this image, also, I think I had not perfect focus.
The Lagoon Nebula (catalogued as Messier 8 or M8, and as NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. It is estimated to be between 4000 and 6000 light-years from the Earth
The Trifid Nebula, also known as M20 or NGC 6514, is also located in constellation Sagittarius at an uncertain distance between 2000 and 7000 light-years from the Earth. This very beautiful object is an unusual combination of an open cluster of stars, an emission nebula (the red portion), a reflection nebula (the blue portion) and a dark nebula (the apparent ‘gaps’ within the emission nebula that cause the trifid appearance; these are also known as Barnard 85).
