Check out this excellent guide on luminosity masks. You'd be after the dark masks part.

Which software package are you using? Harrys astro shed has some really good stuff for pixinsight.

Yes, should point out that I assumed PhotoShop since the term "layer" mask was used. If I get a chance over the weekend, I have PS actions for luminance masks as per the link I gave above, and also have similar process icons using pixel maths for PixInsight if that's what you're using.
