Reprocessing 2022 records focused about M42 region.
In this work there’s a main core in LRGB, background removed, SPColorCalibrated, Deconvoltued and denoised is then integrated and boosted by Ha and Oiii narrowband master (Bgremoved, Deconvoluted and denoised) with Ha applied to L and R channel, Oiii to Green and Blue.
Final starless and 0.65 stars pixelmath blended and Photoshop retouches.

In this workflow I used Ha narrowband as integration for Luminance and Red channel, and Oiii narrowband master as integration for Green and Blue channel as according to Kayron Mercieca, cfr.: https://www.lightvortexastronomy.com/tutorial-combining-lrgb-with-narrowband.html
Approved subframes detailed list (PixInSight weighted) resumed gathered by filter, all by Astronomic, recorded between 28/10/2021 and 25/04/2023.
Ha: 226 x 180″ -20C: 141 gain 139, 85 gain 173
Oiii: 159 x 180″ -20C: 94 gain 139, 65 gain 173
L: 636 x 60″ -20C: 553 gain 139, 83 gain 173
G: 532 x 60″ -20C: 373 gain 139, 159 gain 173
B: 500 x 60″ -20C: 298 gain 139, 202 gain 173
R: 614 x 60″ -20C: 438 gain 139, 176 gain 173
IC 2574 in HaR OiiiG OiiiB, William Optics Redcat 51, ASI1600mm Pro at Bin1, -20C: RGB subframes of 60″, Ha and Oiii subframes of 180″
Ha is used as integration of R channel, Oiii as integration of G and B channel by PixelMath, PixInSight.
IC 2574 (Coddington’s Nebula) – Intermediate Spiral(SABm) Galaxy in Ursa Major, an intermediate Spiral(SABm) Galaxy in the Ursa Major constellation, situated at about 17.000 Ly from us, appears close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere.
It is an outlying member of the M81 Group and is currently forming stars; a UV analysis showed clumps of star formation 85 to 500 light-years (26 to 150 pc) in size.

Comet C-2022 E3 ZTF from Livorno, Bortle 6 degree suburban sky.
Rare minutes of clear sky let me take about 10 subrafems of 60″ in LRGB between 4 and 6 a.m..
Very hard set to combine due to comet alignment shifting parameters.
Postproduction PixInSight, StarXtermintator, Adobe Photoshop.
