About The Image
Color Info	The image is a composite of separate exposures made by the ACS 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: Red: F814W (I) + F658N (H-alpha + [N II]) Green: F625W (r) Blue: F435W (g)
