| Instrument | HST>WFPC2 |
| Exposure Dates | September 5-6, 2008, Exposure Time: 38 minutes |
| Filters | F336W (U), F502N ([O III]), F631N ([O I]), F656N (H-alpha), and F658N ([N II]) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Five filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Red: F658N ([N II]) Yellow: F656N (H-alpha) Green: F631N ([O I]) Cyan: F502N ([O III]) Blue: F336W (U) |
