Naked Eye Limited Magnitude

I think this is pretty cool, I've been making estimated limited magnitude readings for nearly a couple months now but this PDF explains and shows it very well.
Its also well worth taking a look at the My Dark Sky website who uses NELM and SQM reading sent in to map the UK so we all have a better idea of where the dark skies are.

Try it yourself just download and print.
