After processing James Webb Space Telescope raw calibrated .fit data focused about NGC2070 by Photoshop screen colorized blending layers, with colours assigned according to NIRCAM filters guideline (cfr.: https://jwst-docs.stsci.edu/jwst-near-infrared-camera ) I was able to obtain this preliminary result.
According to spectrum values indicated by NIRCAM filters guidelines I decided a different approach for postproduction, considering the lowest nm values as “blue” colour band, the middle nm values as green, and the highest nm as red channel for an RGB combination.
Using Pixelmath I thus combined in PixInSight f090W and f187N masters creating my blue channel, f200W and f335N as the green channel, and f444W master for red channel.
Being NIRCAM data results of very narrowband recordings, I approach such masters as a peculiar SHO integration, and decided to attempt a starless integration for nebula details and colours work, and final recomposition of starry image using star luminance layer.
Starless version of each master I obtained by PixInSight > Starnet2. Each master I then stretched and export as .tiff in Photoshop for contrast adjustement, star residual removing and hot pixels fixing.
In Photoshop I imported each master into pertinent RGB channel. Then I provide to contrast, saturation and Brightness adjustement layers and fix other pixels problem emerged from channels combination.
Starry NIRCAM f444W filter master as luminance was finally imported as upper layer in luminosity blending mode, while starless f444W master for starless version.
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 600″ x LRGB subframes, taken between 28/01/2022 and 01/02/2022
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.

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.
