Amateur astronomers worried that Big Astronomy would render them obsolete can relax: the kinds of techniques used to create huge virtual telescopes are now being applied to the huge collections of astro-pics published on the Internet. 
As keen astronomy-watchers know, the effective aperture of telescopes can be expanded by linking multiple instruments in different parts of the world – in radio-astronomy, this is the principle behind the Square Kilometre Array, and the same techniques can be applied to optical telescopes (for example, in this proposal).
Such linking, however, is tightly-managed so that the images can be correlated, corrected, and merged to create a single composite. What’s different about the proposal in this paper at Arxiv is that its authors, led by Dustin Lang of Carnegie Mellon University (along with David Hogg of New York U and Bernhard Scholkopf of the Max Planck Institute in Germany) is that they want to correlate and combine the vast store of astronomy images that amateurs publish on the Internet.
