Last night @astrokiwi.bsky.social showed me that you can actually see the Milky Way from inside the city of Christchurch!

It makes such a difference what sort of street lights are used and especially where they're pointing. In Montreal, the newer lights only shine on a smallish area straight down, and it's much better than the old ones that blast light in every direction...!@jaddle @sundogplanets This is a very likely explanation. I heard of some places that mandate streetlights not spill upwards, and other places switched to colors (incandescent) that were easier to filter out for visible light astronomy.
Now that we have LEDs that can be set to nearly any frequency or range of frequencies, I would look again at rules for what color(s) they are allowed to emit.
