About The Image
Color Info	The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Six filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: White: F673N ([S II]) Orange: F658N ([N II]) Brown: F656N (H-alpha) Cyan: F502N ([O III]) Blue: F469N (He II) Purple: F373N ([O II])
