| About The Image | |
| Color Info | These images are composites of separate exposures acquired by the ACS and the WFC3 instruments 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: Edge/Nebula Blue: F555W (V) Green: F555W (V) and F814W (I) Red: F814W (I) Central portion of Westerlund 2 Cluster Blue: F555W (V) Green: F814W (I) Red: F125W (J) |
