The image is a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges matching the emission of specific chemical elements. One filter was used to sample a broad wavelength randge in the visible. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F502N ([O III]) blue
F656N (H-alpha) green
F673N ([S II]) maroon
F606W (V) white
