I’m not entranced with M42, it’s just kind of big and blah. I came across though a sequence I had taken and processed in January and decided to re-do it to see if my siril processing skills were any better. I would say not. Both images below are based on 60(!) 15 second shots at ISO 800. The second is the reprocessed one which theoretically would have better background removal and color calibration. The only thing I’d say is that i probably raised the black point more on the second one. I’m not sure why i did so many short exposures – maybe full moon or snow cover. it would have been better to lower the ISO and do fewer longer shots just to shorten processing. And I still don’t care about M42.
