This is my best image yet.  https://astrob.in/j39mte/0/

All processing was done in PixInsight.  WBPP with CosmeticCorrection was used with 30 flats and 30 flat-darks.

25 600s exposures were taken using the L-extreme filter.  RGB channels were extracted from the stacked master.  A color image was then made using PixelMath as follows:
R: .917*R + .071*G + .0336B (simulated Ha channel)
G: .083*R + .929*G + .9664B (simulated OIII channel)
B: .083*R + .929*G + .9664B (simulated OIII channel)

The idea here was to do a quasi-HOO palette.  I'm not sure if I did it correctly but the resulting image was a bit better so I went with it.

Thanks,
Casey

Your stars are great to start with so that’s good, but it seems that your gain might be too low? Check your R channel I would recommend you try using that for Luminous and see What you come up with!
