| Instrument | HST>WFC3/UVIS |
| Exposure Dates | August 2, 2009, Exposure Time: 1.8 hours |

| About The Image | |
| Color Info | This image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Four filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F438W (B) Green: F555W (V) Red: F680N (H-alpha + [N II]) + F814W (I) |
