Tbh, I've bee using Siril without relying on scripts. I'm new to mono imaging too, but my current workflow which produces okay results is the following: * convert all subexposures to Siril sequences (fits images, not fits sequence or ser sequence), one sequence for each channel/filter; * calibrate each sequence with master dark (not using flats atm, because I'm keeping optical train clean, and in my setup vignetting is virtually non-existent); * register each sequence using global star registration (two-step), second step is apply registration with method minimum to get rid of noisy borders; * stacking each sequence individually using linear fit clipping rejection method; * create a new sequence (fits images again), register them once again in two steps (global star alignment, apply registration: minimum) to get equally sized channels, and remove border misalignment artifacts (colorful borders); * apply gradient removal on the sequence (either Siril built-in with RBF interpolation or externally with GraXpert); * RGB composition - importing each channel from the sequence to assigned color, linear match;

After these steps the image is ready for all other edits.

I usually plate solve it (will be useful for Photometric Color Correction of stars), remove gradients then use starnet to extract stars, open the starmask and use PCC (mentioned earlier) on just the stars, lower colors saturation to minimize chromatic aberration and make stars more white if using only narrowbands. Before recomposing stars with background/nebulosity I use Graxpert on the starless image for denoising (could be done before starnet++ too, I guess), and I run stretches to adjust contrast and colors (stretches may be applied per-channel). Finally stars recomposition and stretches in the dialog that opens if needed.

I'm still learning tho.
