This filter is recommended for aperatures 10 inch and up as it will also cut back abit of the "good light". There is another version for smaller aperatures. Orion put out their versions as well and are about half the price and from what I hear work OK as well. Don't expect over the moon results with these types of filters but they are better than nothing for visual. Everything that helps if worthwhile IMHO.

This matches my experience as well with this filter...
The other thing to keep in mind is that in a light pollution situation, sometimes it is difficult for your eyes to ever get dark adapted...this is also a hinderance to pulling out those faint fuzzies from town...
The DGM Optics narrow passband filter is also one to consider...
