by Bob Lombardi

Last revised: September 22, 2008

On this web page, you'll find the complete text of a book originally written to help someone who has successfully built their first telescope design and build their second telescope - or third. There is a companion software package to help with calculations presented in the book. The book is presented as a series of Adobe Acrobat files. Chances are you have an Acrobat reader.
