Question: when you say you have mag 3 skies, what scale are you using? I may not understand the scales too well. I read up on the Bortle scale and determined that my skies are about 5-1/2. I thought they said that the lower numbers referred to darker skies and the higher numbers referred to more polluted skies. Do I have it backwards? I haven't studied other scales, so I don't have a clue what to estimate. Just curious.

Just NELM. That is, if I walk outside most nights, the dim objects I can see are about mag 3.
