When is the best time to shoot the star track?

It is best to shoot the star orbit from 9: 00 pm to 4: 00 am. Use my website to query through photography skills, and it is best to shoot the stellar orbit from 9 pm to 4 am. From 9: 00 p.m. to 4: 00 a.m., the camera is not easy to fog, the weather is cooler, and the cloudless sky in Wan Li is the best at night. Finally, avoid the moon, for example, it is not recommended to shoot two weeks before and after the fifteenth lunar month.
