     The largest amateur scopes seem to be of size 1
    meter. Two meter and larger scopes are available at
    Some meter sized scopes available to amateurs:
    The Searchers.
    The World's Largest Amatuer Telescope Draws Scientists
    to the Wilderness.
    Dan Bakken & Hercules.
    The observatory of Puimichel.
     The Faulkes telescope project might be especially
    useful. It provides access to two meter scopes for
    educational purposes:
    Faulkes Telescope Web Site.
    "The Faulkes Telescope Project is the education arm of
    Las Cumbres Observatory Global Telescope Network
    "Our aim is to provide free access to robotic
    telescopes and a fully supported education programme
    to encourage teachers and students to engage in
    research-based science education.
    "Access to our resources and those of our partners is
    provided at no charge to teachers and students."
