Even at magnitude 11.40 240 sec exposures blew out the Nebula. I rescued it by using Histogram transformation in PixInSight. I adjust the center slider to the right, lower the exposure intensity. I then used StarNet++ to split the fore and background stars. I only worked the over colored stars and re-combined with Pixel Math.

I had taken 13 images but lost the sky to clouds,,,,I dumped the last 3 after using "Blink" in Pix and discovered the last three were garbage.....
