Color: This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
F225W (UV), F336W (UV), F438W (B), and F487N (H-beta) blue
F502N ([O III]) and F547M (y) green
F657N (H-alpha+[N II]) and F814W (I) red
