    Hypertelescope at 550 AU

    Would it make sense to palce a hypertelescope at the solar gravitational focal line of, say Proxima Centauri b? Or is there some reason this would not work or be an improvement?

    Improvement over what? How does that differ from what you'd normally do to observe Proxima Centauri b with a solar gravitational lensing telescope?

    The reason I wondered if it would work is because I don't know how tiny the focal point would be. It doesn't make sense to put two telescopes a kilometer apart if the observing area is only ten meters wide.
    I don't know enough about gravity lenses and hypertelescopes to know if there are other reasons it might be a nonstarter.

    You didn't mention anything about scale.
    The lines of focus for the nodes of an interferometer with a 1 km baseline would only be about 500 km apart at Proxima Centauri. I don't know of any particular reason why it wouldn't work.
