Release Date:

Color:

This image is a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope using several different filters. Three filters were used to sample broad wavelength ranges. Four filters were used to sample narrow wavelength emission. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F439W (B), F469N (He II), F502N ([O III])

blue

F555W (V), F656N (H-alpha)

green

F658N ([N II]), F675W (R)
