Just an update, I've culled the data down to about 76 exposures by excluding subs with outliers in FWHM, eccentricity, SNR values, and cosmetic flaws.
After a week or so, and a few more iterations of editing, I definitely see an increase in detail compared to my original stack of exposures, through the whole process.
This is the latest iteration, but I think it's a bit overcooked.

I'll be going back to the stack after I stretched it to try another iteration. Maybe a little less reds, I was aiming for something between both my newer and older photo. Maybe a bit more yellow in the center bar, like some images hubble has taken.
