Tried stacking with and without a light pollution filter from my backyard in Phoenix

Last week I shot the Orion Nebula with my 8-inch scope. I took 30 lights without a filter, then another 30 with a cheap CLS clip-in filter. The unfiltered stack was a washed-out orange mess. The filtered one actually showed some dark dust lanes and the core color. The difference was night and day, literally. Anyone have a favorite filter for heavy city glow?

Which specific CLS filter did you use for that result?

Wasn't a filter, @maxb46, that's just the raw data!
