About the colours
Each of these images are a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three 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: Blue: F502N ([O III]) Green: F656N (H alpha) Red: F658N ([N II])
About the data
The Hubble image was created from HST data from proposals 11090 and 11093 : K. Noll, H. Bond, C. Christian, L. Frattare, F. Hamilton, Z. Levay, M. Mutchler, and W. Januszewski (Hubble Heritage Team/STScI).
