Re: Best light pollution filters?

Here is a web page that was sent to me that I found particularly interesting. It does not contain all types of filters but you can see which ones pass the light you want to see and which ones miss the emission line/s and therefore would be a waste of money.... Additionally, you can see which ones call themselves OIII but really aren't.
