You want to know about light pollution? I live in Los Angeles, and we've got it. I bought the 2" filter thinking it might be a cure-all for LP. Not so much, for this reason: UHC filters darken most of the objects you'll be looking at also. For photography, where longer exposures come into play, it's definitely helpful. For casual observing, it's not quite as helpful depending on the type of object you're viewing. I've had great success with this filter viewing a few nebulae and planets, as it makes certain details more noticeable for sure.
Pros: It makes the background sky darker; enhances details on some objects.
Cons: Also dims whatever else you view; imparts a blue-violet cast.
For a change of perspective, it's great to slap on a filter and see what you might be missing. I'm glad I bought it, but wonder if one of the other filters available would be better at increasing contrast without imparting so much color.

Happily the background sky looks natural through this filter and many stars are visible - I didn't know what to expect. The summer conditions have only allowed me to view the Ring and Dumbbell Nebulae under fairly light polluted conditions, but that was encouraging enough that I now look forward to more extended nebula and better seeing.
The filter threads seem to work ok in some eyepieces but get stuck in others. This may have to do with the different makes of EPs, adapters and barlows that I use and is probably not a filter issue. So far this filter looks very good.
