Which number on the scale best correlates with

your darkness conditions, and what can you see? To standardize things let's say under good, but not exceptional conditions. Although my wife disagrees, we're definitely about a 7 here, and that's under good conditions. I can make out the big dipper, the constellation Orion (I can see that Betelgeuse is definitely red, mistook it at first for mars being far away lol) and Cancer. There's probably more I can see but no telescope or binonculars and still trying to learn the constellations under trying light conditions.

You don't have to necessarily address my post here, but I think it would be fun for members to post their number, maybe scope size, and some of the notable objects they can see just for fun.

Does the emoticon mean you can't see anything....?

Anyway, at least in TX you can't be too far away from a dark sky. It doesn't get any better than 3 in the whole country here, and that would be hours from me.

The light pollution from the baseball parks, sports fields, plazas, and car dealerships is so bad that I can barely see the core of M31! The only salvation is when I get the gear out at 5 AM. The baseball parks and sports fields turn their lights off and I can see a tiny bit more.

Most constellations are completely missing several stars with the naked eye. I can't wait until a hurricane kills the power around here for a week or two. I think that only then will people realize just how much light pollution there is.

I have semi-dark skies about 20 minutes away and fairly dark skies an hour away. Other than that our Bortle 9 skies can ONLY be explored with astrophotography.

Might be worth a longer commute in the future, maybe. What's your personal sense of satisfaction when you're out in a fairly clear 9 sky? That's its worth it overall...?

Certainly! You just have to shift your interest into satellites, double stars, planets, clusters, and brighter nebula. After seeing something like TOPEX/Poseidon, a bright ISS pass, Saturn, Jupiter, or even the Orion Nebula it's well worth it though.

If I am able to distinguish the bands on Jupiter, the rings on saturn, some of the sattelites, find some nebulae and star clusters, and be able to split some doubles which will show their color difference right into my eye I think I'd be happy.

Aside from nebulae -- and to a lesser degree star clusters -- all of those are every bit as easy in a bright city as in the most remote rural location.

This may seem like a voice of discontentment, but its a sad state of affairs when we begin to settle for less and less and even less. I live is not so good skies and its very frustrating. I am trying to see if I can improve things where I am but its a rough uphill battle. Everyone afraid of the dark.

You should be able to without a problem. With an 80mm apo refractor and a 9mm eyepiece I can clearly split doubles and see color differences even from my front yard (which is far more light polluted than the back yard).

Currently, a 4 bordering on a 5.

20 years ago a 3.

40 years ago 1-2 and at 50+ years it must have been a solid 1 here...all at the very same location! Yet, I'm regarded as lucky by many!

On an average night, 7.
On a rare, very good night, 5.

To the person who posted earlier, I wouldn't say I'm satisfied at all, but personally considering I live in a metro area of 20 million or so I'm thankful for what I can see. Just a five mile ride towards the center of the city would let me see only a few dozen stars under good conditions. Under bad conditions people there can only see objects less than magnitude 1.

Would those of you who replied mind stating what are some favored objects that you are able to see from your mostly mediocre conditions

you know things are bad when a local power blackout makes things from 9 to just 8.

Ouch, well its definitely a 9 here most of the summer if not worse because of air pollution, as I'm doing more naked eye observations, I'm also realizing it's at least partly cloudy a lot more nights than I realized. You don't think much about a partly cloudy night when you aren't observing...

Well let's see hear I'd like to finish this off by comparing the amount of stars we can cover with one hand, naturally in theory only. My hand's on the small side and if I hold it up high it will end blocking on average 5 stars. I heard Betelgeuse is *BLEEP* about this so be careful around him.

That's too vague; the star density varies immensely from one part of the sky to another. At a typical suburban location it could easily vary from 20 in and around Orion to zero in parts of Aquarius.

Well you're right about that, especially when you have a washed out horizon to boot. Don't have twenty in any part of the sky here tho. But yes even straight up I can see a variance. I'm working on talking my wife into us moving to one of the few green zones in the country, she seems suprisingly receptive so far but we'll see how long that lasts

Just for sake of discussion I just went outside 5 minutes ago and counted all the stars visible from my backyard with the naked eye. Mind you I only gave myself about two minutes to acclimate to the darkness. Also the moon is quite full but not totally full. In any case I counted every star I could see. The grand total: 27. Yep. I can only see 27 stars with the naked eye. You guys that live in areas with less light pollution don't know just how good you have it. I remember looking up at a full moon sky and seeing countless hundreds of stars still visible. Not here.
