    Visual impressions

    Planets and some stars show a limited amount of color. Galaxies and nebulae show none. The Orion nebula looks slightly green to some observers. Below you can see two images of M42. One of the images was processed to simulate a telescopic view.

    Color can only be seen in the bright objects in the night sky, such as stars, planets, and bright planetary nebulae. However, experienced amateur astronomers realize that very few deep-sky objects, such as emission or reflection nebulae, will show any color at all visually, even in the largest telescopes. This is because most objects are just not bright enough to stimulate the eye's cone cells in the retina which detect color. The rod cells in the retina, which are sensitive to faint light, see only in black, white and shades of gray.
