The only time I used auto-dev is to show any errors due to dithering so I know where to crop, changing between redo global stretch or stretch as is will give different results as well. Keeping the stars out of the colour module will stop the stars from blowing out and taking the focus away from the nebula. I do my mask early so a lot of the modules I do, deal with the nebula/galaxy, for me that has made a big difference.

When I stack my images I'll register them and not stack so I can check the FWHM on all the frames and then see which has the best score which them becomes my reference frame. The lowest score sub I check to see how bad it is, whether I've bumped the scope or a gust of wind moved it, any movement of the stars I de-check that image from the list. In the end you have only the best subs for stacking and the best of the best as a reference.

I can't think what my setting are at the moment for DSS and Star Tool adjustments vary, I rarely leave anything default anymore.

I don't use BYEOS or APT anymore, they're not bad programs but have found better in so may ways.
