Silly question. Can you do a "drive by". In other words not slow down. How much time you need to "take the photo". I am using terms like Randall in Thing Explainer here!!

Maybe it has further missions in deep space after that. Or look in other directions and use other stars.

I've actually just finished watching the video linked elsewhere in this thread and a drive-by is exactly what they propose, using multiple telescopes launched on staggered schedules in order to make repeated observations and gradually refine the image.
