telescopes and the result of a two-year design effort at the Meade Irvine facility,
take previous telescope technology to a level heretofore unimagined. Announced in September, 2001, few telescopes in the thirty-year history of Meade Instruments have aroused such intense interest, or been so quickly accepted, among both beginning and experienced amateur astronomers, but
did.
