Nit: Lucky imaging requires multiple frames, not long exposures. In short, you need multiple frames to be able to reject any. Long exposure times are still important for astronomy because they improve the noise floor.

long exposure was intended to describe the photography analogy.
Im not an expert in digital radio astronomy, but my understanding is that data is generally sampled at a high rate.
