@sundogplanets so sad when I saw my youngest son getting excited about pursuing using telescopes as a hobby. He spent a bundle on 2 types for use in the backyard. In 2014. In Phoenix, AZ.
Aargh. Since then the urban light pollution has gotten so much more pervasive. And then came the satellites. So so many satellites. Those telescopes have been packed up for almost ten years now.

@sundogplanets Yes! When we are at our cabin in the Upper Peninsula you can just watch satellite after satellite go by. It makes watching the night sky difficult and not very fun.

@sundogplanets City lights are (in some places at least) becoming better planned and less wasteful (I've done a few years in the smart street lighting business).
As systems are upgraded
* LED lighting uses less power than previous technologies
* switch on/off times can be calculated/measured more accurately, so lights are on for less time (they don't have to be switched on a few minutes early in order to be sure of meeting the regulatory spec)
* lights can be switched off in the middle of the night (which annoys punters) or dimmed down (which punters don't even notice, so is sometimes more politically acceptable)
* I'm assuming that better housings are also directing more of the light downwards rather than upwards.[There are also places which do weird stuff like dim the lights down when there's nobody around and then brighten them when cars are detected. This seems arse about tit to me - cars have got perfectly good headlights, it's pedestrians and cyclists who need help from the street lights.]
I realised at one point that I had all the passwords necessary to turn the lights in a particular city on and off so as to look like a smiley (or even a rude slogan) from overhead. But I never did, even when I was working out my notice.
Does anyone with the passwords feel like having Clacton say VOTE BINFACE as seen from a couple of thousand feet? It'd cost you your job, but plenty of people would cheer you on.
Oh, and one strange factoid as an aside: it seems that half the "street lights" in the USA are not lighting streets at all - they're lighting car parks.

@sundogplanets Yup. As a kid (a long time ago) I was able to see the Milky Way and the Magellanic Clouds from my backyard (I grew up on South America, on a suburb). Now, here on this Italian city sometimes it's difficult to see planets, let alone stars, due to light pollution.

@sundogplanets I will be at one of the few locations in my country that has excellent night sky visibility in about 2 weeks. It is really eye opening experience when you get from city with ~200 stars visible by eye to place like this.
Unfortunately I get to experience it max once per year. I hope that I will get nice clear weather at that night.

They have, in fact, taken the sky from us. -

@sundogplanets It is the one thing I miss most from my time training to be a merchant mariner now I live in a big city.
I don’t miss the social aspect of life aboard ship. I don’t miss the working conditions. I kinda miss the constant travel. But I really miss the night sky on a deep sea voyage. I miss it a lot. Nothing like it.
And now even that’s not the same anymore.

@sundogplanets I remember about 10-15 years ago when NASA meetings or dinners were paused to watch the ISS passing over. It was visible in small cities

@sundogplanets The local astronomy club I'm part of did a Perseids viewing for the public last night. We got about 200 people out and one thing that really struck those new to this was just how bright the nearby urban developments were. They were kind of depressed about it after showing them all the cool stuff to look at.
We'd show them M13, M6 and others in Sagittarius because the above and south view was mostly dark. But showing them M31 was tough because of all the light in the north and east. Multiple people gave that look of disappointment when you explained to them it was city glow making this difficult.
Also, I did not hear much enthusiasm for satellites. Because they were not meteors.

@sundogplanets @ariadne Living in London now I can't see much of anything. When I was younger I spent a lot of time north of Toronto. I remember the first time I really saw and appreciated the Milky Way, understanding instantly why it was called that.
I remember one evening 30, 35 years ago standing on the side of a lake with an astronomer describing everything. Pointing out the satellites because they were so rare and fleeting.
It is truly amazing when you really get to the see night sky.

@sundogplanets in Winnipeg, it usually just takes me a few minutes to spot a satellite. I didn’t know they were mostly starlink until I tried to see what they were. The starlink filter on heavens above is huge.
I have mixed feelings about sodium lights replaced by LED. Down facing better, but brighter & harder to filter. Purple was fun. They should be red (hah) so I can view the sky better, not on, or on-demand (motion censors, pressure sensors, magnetic sensors, cameras etc.).

@cobalt123 @sundogplanets it is. Binoculars are a great way to keep active watching the night sky. I know many that keep a pair in their car (along with a star chart/book).

@sundogplanets i've taken cpl cross-country (US) train trips, and was amazed to see total darkness. city-born, suburb raised, suburb living now, never see that. a single driveway light stood out as a lost soul in a very dark wherever we were. not much else to look at on a train at night. the sky, the sky..

Oh, and one strange factoid as an aside: it seems that half the "street lights" in the USA are not lighting streets at all - they're lighting car parks.
In Suffolk we've got the new LED streetlights pretty much everywhere and they get switched off after about 23:30.
There is slightly less light pollution, but what now happens is there's an "arms race" for security lighting on private dwelling houses - some folk leave their "low level" LED lights (not all of which are properly angled) on all night and others have IR triggered lights which randomly go on and off which can be jarring (and when driving at night sometimes make you think there are vehicles behind you which aren't there)

@vfrmedia @sundogplanets Interesting. That "arms race" was never mentioned whilst I was in the business.
I know about IR triggering. I considered connecting an IR triggered light to the burglar alarm until I discovered that it was continually being set off by cats and hedgehogs.

@TimWardCam @sundogplanets I do live in a suburb of Ipswich which once had a bad reputation for petty crime but got cleaned up to a great extent since about 2007/8 to the point house prices rose, its now popular with middle class familes and seniors, they still have a (maybe understandable) fear of crime and are determined to protect their property (every other house also has some kind of CCTV doorbell and often cameras guarding vehicles on the driveway if they have one)

@vfrmedia @sundogplanets Ah, Ipswich.
I recall an incident when the police called the council and said "hey, we think something might be going to happen in the city centre on Saturday night, can you leave those lights on all night please?"
On this occasion there was a couple of days' notice, but I think the council had to have someone on call 24/7 to switch the lights on at the request of the police if there was an emergency.

@sundogplanets they know, it’s all of it. That’s what they have lost. They don’t have the view or the time to appreciate it. For them a star, a planet, or a high flying plane are all the same thing. Until satellites start landing in cities they aren’t personally invested.
