Color: This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. 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:
INT: H-alpha cyan
ACS: F606W (V) blue
ACS: F814W (I) red
