| Color: |
This image is a composite of many separate exposures made by the WFPC2 and ACS instruments on the Hubble Space Telescope using several different filters. Three filters were used to sample various wavelength ranges in each instrument. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
|
WFPC2 |
|
ACS/HRC |
| F410M (Strömgren v) |
blue |
F550M (R; POL0V) |
cyan |
| F547M (Strömgren y) |
green |
F550M (R; POL60V) |
yellow |
| F656N (H-alpha)+F1042M |
red |
F550M (R; POL120V) |
magenta |
