Details:
These are 4 views of the Horsehead Nebula, which I previously posted, captured from Rome using the Dwarf II (mini version). The original "Dual Band" (Ha+OIII) version is shown in the top-left panel. As noted in the image caption, I also performed a "true" HOO (Hydrogen-alpha/Oxygen-III) process. Processing note: All images are derived from the same dataset (Ha + OIII).
Processed using AstroWizard & Siril to ensure a consistent standard.
The HOO version represents the true palette based on actual data.
The "Pseudo-SHO" (orange/blue) and "JWST-style" (cream/red, reminiscent of the James Webb Space Telescope) versions are aesthetic simulations. No actual SII (Sulfur-II) data was captured; the SII channel is synthetic—a point I am, of course, explicitly stating.
