Artificial lighting in urban and suburban areas brightens the night sky and reduces contrast, making faint deep-sky objects more difficult to observe. Skyglow caused by streetlights and industrial lighting often overwhelms delicate nebular structures. Unlike galaxies, globular clusters or reflection nebulae, emission nebulae radiate light at specific wavelengths. Because the human eye has limited sensitivity in the red spectrum, only the O-III and H-Beta lines are easily visible visually. Cameras, however, can record all these wavelengths, including the deeper red emissions.
