Orientation/Scale:

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:

F336W (U)

blue

F547M (y)

green

F657N (H-alpha + [N II])

red-orange

F814W (I)

red
