       | Without beautiful images, the appeal to amateurs is very weak.
       | How complicated would be to use one of these for scanning so we
       | can obtain an image of the sky?

       | (Society of Radio Astronomers). A personal long-term project is
       | to use basic RA gear - which includes TV antennae - to
       | demonstrate detection of (strong and well-known) pulsars.
