A technical term in photography: starry mountain?

Starlight refers to the light sources in the shooting picture, mostly the sun and street lamps, which are generated when the aperture is very small, making these light sources look like stars in the picture and have many clear light thorns. You should be able to imagine this description. There is also a filter that can create the effect of starlight shining, called starlight mirror. The number of light thorns is related to the number of blades in the lens aperture.
