Trying something different in editing Orion nebula

Hello people. So, last night I was trying to photograph Orion nebula with my camera and some vintage telephoto lens that is not sharp at all even when stopping down aperture. I made pretty short overall exposure for this photo because something happened with my camera and it stopped working, after few minutes it started working again but I didn't had time to photograph again because I had to go somewhere.

I did something that I've never done before when I photographed this nebula. First I stacked every exposure that I had, then lightly edited photo and saved it as TIFF 16bit file.

After that I used some software called StarNet++ which gave me starless photo with only nebula in photo, mostly. After I got that next thing to do was combining two photos together to get much more nebula in photo. It was better than just editing one TIFF photo, by combining these two images overall photo came pretty good.

This is just single exposure photo just for you to see how it is better to stack photos than editing single exposure. Noise here is pretty noticeable.
