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.obin

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.obin

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!BrooksObs

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.
