| Color: |
These images are composites of separate exposures made by the ACS instrument on HST. Each filter was used to sample a narrow wavelength range. The composite colors result from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
F658N (H-alpha+[N II]) |
red |
F625W (r) |
blue |
