These remarkable nebulae are close together both within a field of view of 2 degrees and in distance from Earth (4300 light years for the Lagoon Nebula bottom right and 5200 light years for the Trifid Nebula, top left. Both are bright enough to be directly observed through the eyepiece but long exposure astrophotography and the accompanying post processing techniques make them stand out especially with the varied colour of the smaller Trifid Nebula.
