| Instrument | HST>WFC3/IR and HST>WFC3/UVIS |
| Exposure Dates | July/August, 2009, Exposure Time: 23 hours |
| Filters | WFC3/IR: F140W (JH) WFC3/UVIS: F438W (B), F606W (V), F657N (H-alpha + [N II]), F665N (H-alpha + [N II]), and F814W (I) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Six 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: F606W (V) Red: F140W (JH) + F657N (H-alpha + [N II]) + F665N (H-alpha + [N II]) + F814W (I) |
