Project AstroFly Examples: Colors of Stars of the Constellation of Orion


This image, generated by AstroFly, shows the stars forming the constellation of Orion, depicted with their "real" colors. The term "real" means that the color of a depicted star corresponds to the color that the human eye would perceive if the light from the star was not affected by the Earth's atmosphere. The computation of each star's color is based on its effective temperature; the detailed description is available in the AstroFly Help.
(No gamma correction was imposed on this picture.)

Compare the colors of stars in the above image with those in this impressive photograph.
