Science Team: |
This image was created from HST data from proposals 8133: P. Shopbell (Caltech), R. Dufour (Rice University), D. Walter (South Carolina State University), and A. Wilson (University of Maryland); and 10885: A. Aloisi and M. Sirianni (STScI/ESA), J. Mack and R. van der Marel (STScI), L. Angeretti, D. Romano, and M. Tosi (Astronomical Observatory of Bologona/INAF), and F. Annibali, L. Greggio, and E. Held (Astronomical Observatory of Padua/INAF). A. Grocholski (STScI) is the lead author on the science paper. |

Color: |
The image is a composite of separate exposures made by the ACS and WFPC2 instruments on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. One filter was used to sample broad wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
| ACS |
F658N (H-alpha + [N II]) |
red |
| ACS |
F606W (wide V) |
green/cyan |
| WFPC2 |
F502N ([O III]) |
cyan |
| WFPC2 |
F487 (H-beta) |
blue |
