Every Celestron enthusiast will find this work fascinating! This unusual E-book (CD-ROM) is the most comprehensive work ever assembled on the early history of Celestron, and the early telescopes they produced. Part history book, part shop manual, part technical encyclopedia, part photo album, it tells the story of Tom Johnson, Celestron’s founder, his company, techniques, and telescopes, from their inception, in 1963, and how they evolved over the years. Information you will find NOWHERE else. Produced with full cooperation of Celestron. It also contains current interviews of 15 of their early personnel. Nearly 1300 pages of easy-to-read text, TONS full-color photographs. Too big to put into printed form at any reasonable price. (The photo shows a collage of compressed photos from the disc. The images on the disc itself are all HI-RES)
The PDF disc can be read with Acrobat Reader 4.0 or higher. (Windows 98 or higher recommended) It can also be read in MACs with appropriate disc & PDF software. (Contact me for MAC specifics.)
If you have either one of those systems, you can access this wonderful book. 75 chapters, all of which can be read or printed by the user at will, showing each of the early Celestron Blue-White scopes, their evolution into Orange-Tube models, and beyond. Technical info on all aspects of Schmidt-Cassegrain design, plus a large chapter on Collimation Techniques, containing some techniques never before published. Anyone who had ever had an interest in SCTs or used one will find something of interest in this book. $49.95 plus $3.00 for First-Class postage and handling in the US. New York State residents add 7.25% sales tax. I accept money orders and checks, as well as paypal. If anyone wishes, I will email them a copy of the Table of Contents and Foreword (Written by Tom Johnson).
