Then used Russ Croman's StarXTerminator to remove the stars from the RGB and from the Luminance, stretched the starless images then put the stars back (stretching them somewhat but separately).
Blend of Luminance w RGB in PixInsight. Moved to Photoshop, added contrast via Curves. Moved to LR to add a linear gradient to darken the upper right corner. Back to PS and Save-for-web.
