Fig. 4From: Astrophotography, a portal for engaging non-STEM majors in scienceThe Orion Nebula. This nebula is a star-forming region as observed with an 8-in. refracting telescope. The final processed image allows the observer to detect as much of the nebular gas as possible. Contrast allows for colors to stand out and provide information upon sight, purple/red indicates the presence of ionized hydrogen, blue/green the existence of doubly ionized oxygen, white is produced by starlight, and irregular dark areas are dust/gas cloudsBack to article page
