you can always do DBE a couple of times if the shot needs it, or keep the subtraction image and use pixel math to apply it again at a different percentage amount. PM is a powerful tool when you understand a bit more about whats needed. A lot of PixInsights tools can be duplicated using PixelMath and that gives you finer control and flexibility. Not an expert myself but part of my workflow uses it, I adapted an unrelated intermediate step from a tutorial I tried.
using STF is great to have a look at whats hiding in the signal to bring out or protect. Another trick I use is to plate solve my starting integration image and render an annotated image. Makes it easy to see if you've got a Messier or NGC target large enough in the shot to try to bring out. Sometime I go back over old data and use dynamic alignment around something i didnt realise I was shooting instead of just the star alignment.
Hope someone comes up with a tool to take all my plate solve integrated images and assemble a full sky mosaic for me or index all the deep space items I've captured
My astrophotography is half random and half planned, I love exploring my shots.
