About the author:
David A. Harbour is a long-time amateur telescope maker
and designer of optical telescopes and mirror testing
apparatus. He is a skilled photographer and pilot and
owner/operator of Great Plains Instruments, of Enid,
Oklahoma. Now retired, he has permitted some of his

Understanding Foucault
By David A. Harbour
David A. Harbour presents a brilliant narrative for the
Amateur Telescope Maker (ATM), on exactly how the "Foucault
Test" is interpreted. Through a series of "foundation
lessons" Mr. Harbour ensures the ATM understands what the
Foucault Test is revealing, and what to do about it as he
figures the telescope mirror to achieve the perfect
paraboloid.
Imagine if the makers of the Hubble Space Telescope had used
this book as a guide to test the HST's primary before
launch! The savings would have been in the millions! Well,
that may be a stretch, but for the ATM, who has taken on the
delightful but challenging task of making his own telescope
mirror, how nice it would be to have a guide to ensure
success!. Success is at hand. Dave Harbour presents a
thorough and informative instruction on just how to be sure
the mirror is perfect! This book is for the ATM bookshelf to
accompany the classics of Porter, Texereau and others.
