What effect does the moon have on stargazing? Does-10 moon have a great influence on stargazing?

Remember the Tang poem I can recite in kindergarten: "My bed feet are so bright, is there already frost?"

The moon sprinkled silver moonlight on the earth like frost? Imagine how serious the influence of the sky will be.

There is a cloud in Cao Mengde: "There are few stars on the moon, and blackbirds fly south". The description of execution in the first half of the sentence is simple and clear, and it is not a loss for Jian' an Sanjie. I still remember coming to Tianhuangping in Anji to observe the Perseid meteor shower on August 13 this year. Due to the influence of the full moon, the observation conditions are not even as good as my community in Shanghai.

First, the moon will drown out the light of some stars. More importantly, the naked eye can't adapt to the darkness, and its light gathering ability is greatly reduced. If you can reach the limit magnitude of 4.5 at the full moon, it is already very good. And this value is not out of reach in a big city like Shanghai.

If you take pictures, the impact may be slightly smaller. After all, the camera has not adapted to the dark light, and the aperture and ISO can be adjusted by themselves. But the conditions for taking pictures of constellations are still not good. As long as the exposure time is long, wait to see the bright moonlight background. However, you can continue to observe after the setting of the first quarter moon these days, and the conditions will obviously be much better. Thinking about ancient poems in the middle of the night: "Thinking about a gentleman is like looking at the moon, and it decreases every night." I'm afraid I haven't felt such an artistic conception for a long time.
