This image was processed before by the Hubble team but in a totally different way. In their image the hubble palette was used, using 3 images. For this image 6 different bands were used:
hst_06227_02_wfpc2_f658n_wf_sci
N2: used as yellow
hst_06227_02_wfpc2_f673n_wf_sci
SII: used as red
hst_06227_02_wfpc2_f953n_wf_sci
SIII: used as magenta/red
hst_06227_02_wfpc2_f487n_wf_sci
h-beta: used as lightblue
hst_06227_02_wfpc2_f502n_wf_sci
OIII: used as blue
hst_06227_02_wfpc2_f656n_wf_sci
H-alpha: used as green
The luminance was made from the SII and H-alpha channels.
In this way much more detail in the center can be seen than in the original hubble processing.
Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).
