Wide View of Spiderweb Galaxy Field

About the colours

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (SDSS g) Green: F475W (SDSS g) + F814W (I) Red: F814W (I)
