Is it just 'star-mask' or 'masked stretch' (both?). De-ringing? I'm playing with tutorials, but nothing seems to be making much difference.

Yes to all that. you can separate the two and work on them separately and yes deringing it vital and painful. the processing always depends on the image itself its NOT a set of values and buttons to push. Its a series of steps that varies depending on noise, faint structures and stars in the image. Understand what the purpose of each step is, some make no apparent change to the image but influence a later step if they were done several steps earlier. Take notes and follow/repeat them, learning and refining as you go, its hard work. Last Thursday I took a set of shots over an hour and I've only just got my subs registered yesterday, with another preprocessing step to go before i can attempt an integration. THEN will come actual stretching processing and no nebulosity in this image. Time and patience. Check out the Light Vortex Tutorials if you havent already, essential reading and learning resource.
Edit: go less agressive in your steps. Often its better to run one process with subtle settings a few times than running it once with heavy settings. Make use of previews to test settings and pay attention to the introduced artifacts, they will always be there but maybe not visible but can influence or multiply with later steps. Remember, signal and noise both exist at different scales in each image, so dont try to overprocess in one go to tackle all scales at once, you can go easy with smaller stepps at each scale separately.
