All i can think of is that it is light pollution.
I grabbed an old DLSR image i had from when i first started.
I get the same thing, but more blueish. I had a LP filter on which gave the image a blue tint.
To remove it you need to get rid of the color cast.
Nebulosity 3 does a decent job of this.
Go Image -> Adjust Color Background (offset).
It will automatically try and find the best setting. If its still redish or whatever, you can play with the sliders.
Click ok and see how that goes.
See attachments for an example.
