Is it feasible to shoot deep space with super telephoto lens?

Telefocus is not designed for shooting at infinity, but it is suitable for shooting relatively distant objects. Shooting at infinity is not suitable for refraction, but for using a mirror. Because mirrors avoid chromatic aberration in principle. For deep space shooting, the reflector is the most ideal lens. In addition, the influence of telephoto shooting on the earth's rotation in the starry sky can not be ignored, and it is necessary to track a constellation with an electric orbiter.
