Looks to me that light pollution has washed out some detail becuase apart from that they are cracking images!

Where did you shoot these? What cmaera? Modded?

I think the first one is a cracking shot despite the skyglow.

I'm no expert when it comes to editing images, believe me, I'm very much in the begginers club, but it looks to me as though your white balance is off.

How are you stacking them? dSS? If you are, set it to align the colour channels and set the black point to zero. Or adjust the whe WB yourself.

I had a few images that came out with the same brown cast and the above helped a lot.

I love that first shot! That's very nicely done indeed and very crisp.
I took the liberty of removing some of that skyglow and recalibrating the colors - hope you don't mind!

Honestly, that's how it's 'supposed' to look in real life - predominantly white (hence 'milky' way). The reason for that is that all the different star colors in the milky way will average to white.

You can actually use this as a pretty accurate technique for color calibration - use all the stars in an image and get the average color, or use a galaxy (make sure it's of the 'white' type) and grab its average color. Since the color you calculated is supposed to be white (e.g. equal amount for red, green and blue), you can now determine how far off the colors in your image are.

All I did was create a gradient model and subtract that from the original image.
