This was a challenging target mainly because half way through imaging over 5 nights, I realized that my secondary mirror had astigmatism, and I had to order a replacement and install it. But I pushed through, and it was worth all the hassle for this image.
Processed with Pixinsight;
Followed LVA's stacking tutorial,
Drizzle Integration,
Dynamic Background Extractor,
Processing the Nebulocity,
Histogram Transformation and match the Ha and Oiii backgrounds as much as possible,
Deconvolution,
Multiscale Linear Transform,
LRGB Combination, R-Ha, G-Oiii, B-Oiii
Starnet Star Remover, This is to remove the HOO stars to replace with RGB stars,
Curves Transformation, boost the saturation and increase contrast,
SCNR at 0.25 on Green, removing a little bit of the green,
HDR Multiscale Transform
Processing the Stars:
Histogram Transformation,
LRGB Combination R-R, G-G, B-B
Curves Transformation, saturation curve to increase saturation and remove a little green from the stars,
Automatic Background Extractor, removes the colors in the background without effecting the nebula or stars,
Combining the Stars and Nebulocity,
Pixel Math, $T + RGBStars, apply this to the HOO image,
Automatic Background Extractor,
Curves Transformation, Make the nebulocity pop a little.
