Here we see conventional telescope pointed at an opaque disk along an axis to a distant target. Rather than block the view, the disk boosts the resolution of the system with no loss of collecting area. This architecture, dubbed the “Aragoscope” by Webster Cash of the University of Colorado can be used to achieve the diffraction limit based on the size of the low cost disk, rather than the high cost telescope mirror used today. One can envision affordable telescopes that could provide 7cm resolution of the ground from geosynchronous orbit or images of the sky with 1,000 times the resolution of the Hubble Space Telescope.
