IC348 SHO Dynamic Narrowband Combination

According to Andre B. [ https://telescope.live/blog/dynamic-narrowband-combinations-pixelmath ] who in turns referred to The Coldest Night [ https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/ ] narrowband channels integration and combination is subjective and could not coincide with a simple channel combination of Sii Ha and Oiii masters within an RGB implementation, as also suggested by Edoardo Luca Radice during CEDIC 2019; cfr. “Creating near true color images for nebulae from narrow band data using PixInsight” [ http://www.arciereceleste.it/tutorial-pixinsight/cat-tutorial-eng/110-cedic19-art?fbclid=IwAR0ybmyfZCC8G2ykfgDavTpBY7tEjE_DhJOAeT_QM5gZpKSvAfSmiNOoznw ]
In my approach and attempt I used PixInSight > Pixelmath formula
R = (Oiii^~Oiii)Sii + ~(Oiii^~Oiii)Ha
G = ((OiiiHa)^~(OiiiHa))Ha + ~((OiiiHa)^~(OiiiHa))Oiii
B = Oiii
to generate IC348 integration and postproduction.

Descrizione
After James Webb Space Telescope MIRI and NIRCAM data, I focused about NGC 1365 Great Barred Spiral Galaxy, and found good calibrated data from Telescopelive archive to be downloaded and elaborated.
Telescope: Planewave CDK24 610/3962mm (CH-1-CCD)
Camera: Proline FLI PL 9000
Location: El Sauce Observatory, Chile

NGC1365, approaching to JWST MIRI data
According to James Webb Space Telescope official documentation (cfr. https://jwst-docs.stsci.edu/jwst-mid-infrared-instrument) the JWST Mid-Infrared Instrument (MIRI) provides imaging and spectroscopic observing modes from 4.9 to 27.9 μm. These wavelengths can be utilized for studies including, but not limited to: direct imaging of young warm exoplanets and spectroscopy of their atmospheres; identification and characterization of the first galaxies at redshifts z > 7; and analysis of warm dust and molecular gas in young stars and proto-planetary disks.
MIRI imaging filter curves and wavelenght are resumed below
From Mikulksky Archive for Space Telescopes I downloaded raw calibrated .tif data focused about NGC 1365 Great Barred Spiral Galaxy, a double-barred spiral galaxy about 56 million light-years away in the constellation Fornax.
Among all data available I picked-up 3 sessions: a wide field MIRI mosaic by filters f770W, f1000W, f1130W and f2100W, a small field MIRI mosaic by the same filters f770W, f1000W, f1130W and f2100W a small NIRCAM field mosaic by filters f200W, f300M, f335M and f360M.
