Release Date: July 31, 2006

This image is a composite of many separate exposures made by the ACS and WFPC2 instrument on the Hubble Space Telescope using several different filters. Five 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:

F475W(B) blue
F502N ([O III]) blue-green
F550M(V) green
F658N(H alpha) red-orange
F775W(i) red
