Lagoon & Trifid nebulae are one of the most interesting deep sky objects visible in summer night skies, in Sagittarius constellation. They are both hydrogen red emission nebulae, enough bright to be seen with a binocular in dark nights.

Here it is an old film photography of the area, that shows Trifid Nebula (Messier 20) and Lagoon Nebula (Messier 8).
