Q
Does this block mercury vapor light too?
Answer Question
A
LPRs are designed to filter both mercury vapor and sodium spectral lines. I cannot answer via personal observation how good of a job it filters Mercury Vapor as my city phased those out long ago. Of note, I would classify this filter as a broadband filter, if you have a higher amount of light pollution you might opt for a narrowband or line filter instead to see better results.
