I have various old aurora shots lying around. Here a few from Svalbard:

At 78N it's dark around the clock in mid winter. These following photos were taken around noon, but when the moon is up, it's reasonably easy to see things:

The last shot is from Mauna Kea in Hawaii. Which has an awesome view of the night sky. For this shot I directed a regular 80mm f/1.4 lens towards the center of the Milky Way and exposed for 16 seconds using 400ISO film, and I was pretty amazed when I got it developed. The naked eye can see some of the details, but not variations in colour.

Damn, north-Europe has nice skies surprised

You are both very lucky; I live in the most light-polluted country in the world and never have auroras either.

More light polluted than Singapore?

^Good point. I suppose many city-states are indeed more light-polluted, logically. I suppose we're the most light-polluted major country only.

Nah, I live in Oslo and there is a lot of light pollution here, and it gets worse every year. The Milky Way is impossible to see most of the time, even in the outskirts. I live a bit uphill, and only when low clouds block the lights from the city centre is it possible to see it if you know where to look. There is a shift now towards "greener" lighting, but it doesn't mean less energy used, just more light for the same bucks. And sodium lamps which can be filtered out pretty efficiently are becoming history. Now it's all about LED and metal halogen emitting a broad spectrum. And the snow on the ground in the dark season makes it really bad, since nearly all light then gets reflected upwards. Here's a comparison that I made a few years ago:

The pictures were taken at the same time of day two days apart, same exposure. The difference is the first October snow.

My Unihedron sky quality meter can reach 19.7 mag/arcsec² in the autumn before the snow if the conditions are perfect, but afterwards it barely ever exceeds 18 mag/arcsec², which is pretty bad. When the snow is gone, the sky is too bright naturally, so September and October are the only months offering reasonably good skies.

We have the option of heading away from populated areas, though, which is impossible in your country.

Yeah, we'd have to travel at least several hundred, if not thousand kilometers before we can find a good place and even then they're hard to find.

Yeah, this is what I meant; I suppose in/near a city there will be heavy light pollution even if that city is on an island in the middle of the ocean. Even in the countryside here, you're lucky if you can see magnitude 5 stars. It's not just the cities; lots of farmland here, especially in the west, uses greenhouses that are brightly lit night and day and even worse than cities (if you look at the Netherlands in SpaceEngine, you can actually see a few glowing yellow spots, even though those pictures were taken at day. Those spots are the largest greenhouse areas)
