Although I am in the suburbs I am not too deep in the suburbs but do have 2 streetlights about 15 meters away in the West one orange and one low intensity white. My Astrodon RGB filters have a spectral gap in the green blocking out 589nm sodium streetlights which helps with mild light pollution. I think Baader green filters have a similar gap.
