Fighting some serious moonlight over a few nights, one set was not useable as per subframe selector. ASIAir pro to acquire ~60 x 300s images @ -10c & 120g for Ha, Sii, & Oiii, ~65% were usable. For RGB, for stars, 10 x 10s images @ -10c & 120g.
Blink / Subframe Select, Calibrated (60 Dark, 60 Flat, 100 Bias), Star Aligned all images with PixInsight. Used the Normalized Scale Gradient for integration.
For Ha, Sii, & Oiii channels: Cropped, DBE, TGV, MLT (& duplicated the Ha here for the Lum), EZ Soft Stretch, StarNet for star removal, and channel combined with Sii to R, Ha to G, & Oiii to B.. The duplicated Ha -> Lum was Mask Stretched, STF Stretched, HDR, LHT, TGV, MMT, EZStar Reduction, and LRGB Combined with the SHO image.
RGB filter data combined with Channel Combination, Image was masked with an inverted Star Mask and replaced with SHO image using Pixel Math to add the nebulosity around the stars.
Final image was Curves modified w/ & w/o masks. DSE, TGV, MMT, Saved as 16 bit tiff to export to PS for further noise reduction. Imported back to PI and Resampled, Cropped, and Annotated.
