Excuse me, where can I find the night sky brightness in major cities in China at present? I mainly want to get a horizontal comparison to see if astronomical observation is feasible.

Brother, your writing skills are really flattering. But I know what you mean.

I searched the internet for a long time, but I couldn't find it. No matter from the perspective of night sky brightness or light pollution.

But there is still a message. Yes, look:

Due to serious light pollution, the Shanghai Planetarium will be relocated.

So, I really can't find official information. However, we can give birth to speculation:

First of all, look at the city with planetarium:

Shanghai, Beijing, Nanjing and Hong Kong Space Museums.

There are no large planetariums in Hangzhou and Shenzhen, so the light pollution there is worth considering.

Shanghai, just excluded.

The capital Beijing has a lot of light pollution, but it can't be too much.

So Hong Kong is an advanced city and Nanjing is an ancient city. It is also the best astronomy university in China.

There will be less light pollution in Nanjing.

Answer over. ?
