| Instrument | HST>ACS/WFC |
| Exposure Dates | July 16, 2009, Exposure Time: 3.5 hours |
| Filters | F475W (G), F625W (R), and F814W (I) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (G) Green: F625W (R) Red: F814W (I) |
