Color: |
The image is a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
F658N ([N II]) |
red |
F656N (H-alpha) |
green |
F502N ([O III]) |
blue |
