Help me process this

Could someone help me process this

 

It's a Tiff filed made kn deepsky stacker from a combination of lights (34 x 180s), darks (5) and flats (15).

I know the original data is not yp to much. It I really struggle with processing and one of the problems I have is that I don't know just what can be achieved from given data so I never know when have maxed out the image, if that makes sense.

Any help would be appreciated.

I've downloaded the tif file, and I can see why you are struggling with it. It looks like the image is underexposed (too little data), probably due to light pollution. You also have excessive banding which is typical for Canon DSLRs. You used darks as calibration frames. With an uncooled dslr, this doesn't always work. Try calibration with bias and flats, where the flats are calibrated with the bias frames.

Here's the extracted luminance, which is an average of the red, green and blue channel and has less noise than the colour image.
