Mike Lindner polishes an 18" mirror

S*T*A*R member Mike Lindner polishes a monster 18" mirror at an ATM (amateur telescope making) session.  Telescope mirrors are among the most accurately made surfaces produced - the difference between a good one and a bad one can be a few hundred atoms thick!  S*T*A*R members can learn how to make a mirror of better quality than those in the majority of commercial telescopes and borrow a grinding stand on which to make one.  For more details see the telescope making section.
