Color

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Three filters sample broad wavelength ranges, one isolates the light of hydrogen. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F658N (Hydrogen-alpha) red/orange
F814W (I) red
F555W (V) green
F435W (B) blue
