thanks everyone. My first attempt at editing. I had some issues again with the histogram. Opening in Photoshop showed the histogram HARD up against the left (clipped blacks) yet the image contained no clipped blacks at all. Switched to 16bit mode and it gave me room on the left to stretch.
Still a heck of a lot to learn here. This was only 11 unguided subs due to high wind (shooting into the wind). I took about double that.
No darks, no bias, only lights and flats (might try it again with all four, I just didn't get good results earlier)
