Beyond imaging, a related paper I came across goes in-depth on identifying the interstellar nodes/constellations to furnish an actual network mesh:
> [ABSTRACT] An interstellar communication network benefits from relay nodes placed in the gravitational lenses of stars. The signal gains are of order 10^9 with optimal alignment, allowing for GBits connections at kW power levels with meter-sized probes over parsec distances. If such a network exists, there might be a node in our solar system: where is it?
