The only light pollution I have are the domes from town (west), and a city/town combination (south). They mainly stay within the 30° airmass unless there's excess moisture in the air. Guess I'm one of the lucky ones.

I'm not too bad here. I don't actually live in Oxford (the nearest City) but in a village 8 miles to the south.

I have mild light pollution (ZNELM = 5.8 on darkest nights) with the local towns causing light domes to the North, East and South-East, the worst of which, to the North is approx. 50 degrees in extent - though like Carol said they get worse with certain atmospheric conditions, especially clouds!!!

Just taken some photos for ya. (Not very good, due to rubbish camera and operator!! )


This is the view from my backgarden (where I do most observing) looking to the North over the houses [and a couple of tall trees].
Surprise, surprise ...it's cloudy tonight!!

And this is the view to the South East, where the light pollution from another town is slightly less.
(It looks brighter though because you can see closer to the horizon than in the other photo)

Living in central/eastern CT, most of the western sky is washed out to 40-45º from the horizon, thanks to Hartford nearby to the west, and New York city to the southwest. Otherwise, the skies are consistently magnitude 6ish everywhere else (on moonless, transparent nights, of course).

I took a couple of photos, but they actually came out pretty dark - so I am lucky. I live in an urban neighborhood that has plenty of street lights, but due to a fortunate and random combination of obstructions, almost all of the direct glare is blocked. I have a very dark corner of the yard that is shielded by trees, 8-foot privacy fence, the house, and the garage. But the price I pay for this localized darkness, is that my view of the north is almost completely blocked up to about 60-degrees or more, and my view to the west is 90% obstructed until you reach the zenith. I can observe to the east with a neighbor's house obstructing the view up to about 30 degrees. I have a good view due south, which is the darkest, but the garage blocks everything below 25 degrees or so.

The western sky is the direction where most of the development is taking place and towards the most populous part of the city. The entire western sky is a bright aquamarine color up to about 70 or 75 degrees. The east is a somewhat darker aquamarine up to about 40 or 45 degrees. The south and the zenith are a moderate navy blue color with a ZNELM of about 4.9 or 5.0 on very good nights with low humidity and low light scatter. On most nights the ZNELM is about 4.4 or 4.5

I would estimate the Bortle class here on the better nights is about 7 (red).

Clear skies,

"..a neighbor's house obstructing the view.."

What's a neighbor?

I have zero light pollution. One neighbor has a motion-sensor light on their approach to their gate, but it goes off in a few minutes. Their house lights are hidden behind large trees.
No other lights around, except a couple yard lights quite some distance away, maybe 8-10 miles.

Hey nytecam,
You can come to my place because I have no LP at all and probably mag 8-10 skies. The only thing that gets in my way is the crazy Georgia humidity. I have resided myself to the fact that fall and winter are the only good times to view here.

Thanks Eric - now this is getting silly with mag 8-10 skies - just bring mark-one eyeball and no need for a scope then

This handheld shot is looking due East toward the front of my home. The glow above the house is from the main boulevard about 8 blocks away. The house is illuminated by the high pressure sodium street light across the street. Yes, it's Moon and Planets only from this location. When this house was built back in 1973 you could see M-81/82 naked eye on a good night. How fast we grow lumens!

Some contrasting conditions in this thread!

Sadly, mine are in amongst the worst. I live between two cities in the Midlands of the UK, right on the border of red and yellow pollution levels as displayed on this page:
http://www.cpre.org.uk/campaigns/landscape/light-pollution/light-pollution-in-your-area

And that's just the ambient area conditions. My house is a 100 year old semi-detached on a "moneyed working class" street typical of that era (i.e. private houses packed in pretty close near the town centre). My back yard is overlooked by the windows of other houses, and very few people bother with blinds or curtains (the people directly behind have amazingly bright indoor lighting). All the neighbours have "security" / yard lights that are left on for extended periods. A new medical centre was recently built two streets away that is massively floodlit all night.

It's basically hopeless.

A 25 mile drive is needed just to get to the mid-blue levels in the link above. It's at least 70 miles to any dark-blue possibility. Note how much the light pollution has increased in the seven year period separating the maps - and that the most recent map is seven years old...

Either Carol can feel free to adopt me. Or both - I have a car.

Carol, I saw this and thought of you:
http://apnews.myway.com/article/20070825/D8R820QO0.html

Even though the meeja drone can't help himself but report it as a problem, the piece is actually covering a sustained economic success story in Montana.

So now is the time to start the campaign for preserving dark skies, otherwise it'll suddenly be too late. Seeing as a big part of the boom seems to be related to the environmental beauty of the state, this seems like a good angle to follow.

Tonk, I'm sorry to hear you fell into your pier excavation, but looking at your avatar, I guess you're well prepared for such eventualities. Try digging deeper, it's bound to go eventually!

Amazing...and pointless. I have a small community of 3000 some 3 miles to the south of me. What sky glow there is can be irritation, but nothing like the picture. I have about 11 acres with trees where I need them, so I have miminal problems. Thanks for the post. I am more grateful for what I have.
