NGC 1491 is a diffused nebula in Perseus with a mag 11 O6-type star BD +50°886 in its center . The radiation from this star is exciting the molecular gas causing the pinkish glow and also forming the bubble around it. The intense radiation is also eroding the gas clouds surrounding it. Above the image is the asteroid trail of Eris as seen through the red, green and blue filters.
