CCDtoRGB produces redâgreenâblue (RGB) composites from threeâband astronomical images, ensuring an object with a specified astronomical color has a unique color in the RGB image rather than burntâout white stars. Use of an arcsinh stretch shows faint objects while simultaneously preserving the structure of brighter objects in the field, such as the spiral arms of large galaxies.
