Why the "petrol filter" is the fix for light pollution

I'm jealous, I have to drive about 30 or 40 miles to get to skies like yours.

Wow - I'm sorry. You must live in a big city. You would certainly be better off with 3 nm narrow band filters to fight LP like that.

Where I live is not all that big really, it just has almost no LP regulation. So it's LP profile is like a much larger city.

Well I've been using the diesel filter the last 6 weeks and I've gone through a few hundred litres of the stuff but I just can't seem to drive out from under all that cloud. Until last night when at 8 pm the skys cleared to show that big grinning full moon. It was like daylight all night. But I tried for some video on jupiter and the moon anyway... I dont expect much but we will see...

They are starting to replace the old sodium vapor lights where I live with LED's. I have urged the city to put dampers on them so the light shines down only and not out into the sky, so far the powers that be have thanked me for my input, but the ongoing resolution of this potential problem is unknown at this point.

The city replaced our street lights a few years ago with LED's and now the street is brighter

Good luck!
