No, the Rayleigh Criterion is still correct, you just have to consider the "aperture size" to be the size of the combined multi-telescope device (which would be the size of the Earth if the telescopes are on the opposite sides of the Earth). In practice to get the best quality image you need a telescope every X meters (I'm not sure the exact distance required) but even a 2x2 telescope array over a large distance would still give you significantly more resolving power than just a single telescope on it's own. |
