M8 Lagoon nebula HST


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.
