The filter size of astronomical camera matches the aperture.

It depends on what kind of scenery we shoot to match.

Generally speaking, a lens with an f/2.8 or above can be called a large aperture lens, which is the best choice for astrophotography. For celestial photography, Lpro filter works well, but deep space photography may have some color cast.
