Colors: This image is a composite of separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope. 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:
F336W (U) purple
F438W (B) blue
F555W (V) + F547M (Strömgren y) green
F657N (H-alpha) orange
F814W (I) red
