Collimating a Newtonian Scientifically
In 2003 my partner Kathleen, proposed a bungalow with a great view of the night sky. December 2005 and one year into telescopes, the optics of the length halved again 8” Cape-Newise got me tasting my own medicine unwittingly and gladly. The confident advertising style mirrored mine for Bailey designed hi-fi speakers, making 100 in the 70’s, exporting 30 to Germany. My approach has been that of being Isaac Newton through the ages, and after each advancement writing down the achievements at the eyepiece. The 3rd edition of March 2014 was still only 16 pages, 6 of which were the instructions and still are. 50 pages of interest were enabled by 2 months in a recliner chair waiting for surgery. Edition numbers change only with improvements to method. They settled down in October 2014 and the 4th edition printings began in March 2015 and have been selling an average of 6 a day at events since 2012. Intuitive adjustments, too easily fallen into, are prevented by following the instructions chapter in this book. The first 2 sentences of stage [1] and all of stage [4] work equally well for Cassegrain type in-line optics. Mirror cleaning, vetted by a mirror manufacturer, has always been included.

This book de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. It demonstrates how inexpensive tools are revolutionizing imaging in amateur astronomy. Anyone with a modest telescope and a webcam can now obtain jaw-dropping lunar and planetary images to rival those taken with mid-range astronomical CCD cameras costing thousands of dollars. A glance through the images in this book shows just what spectacular results can be achieved by using a webcam with your telescope! Your scientific results will be sought by professional astronomers.
The New Amateur Astronomer

Amateur astronomy has changed beyond recognition in less than two decades. The reason is, of course, technology. Affordable high-quality telescopes, computer-controlled 'go to' mountings, autoguiders, CCD cameras, video, and (as always) computers and the Internet, are just a few of the advances that have revolutionized astronomy for the twenty-first century. Martin Mobberley first looks at the basics before going into an in-depth study of what’s available commercially. He then moves on to the revolutionary possibilities that are open to amateurs, from imaging, through spectroscopy and photometry, to patrolling for near-earth objects - the search for comets and asteroids that may come close to, or even hit, the earth. The New Amateur Astronomer is a road map of the new astronomy, equally suitable for newcomers who want an introduction, or old hands who need to keep abreast of innovations. From the reviews: "This is one of several dozen books in Patrick Moore's "Practical Astronomy" series. Amid this large family, Mobberley finds his niche: the beginning high-tech amateur. The book's first half discusses equipment: computer-driven telescopes, CCD cameras, imaging processing software, etc. This market is changing every bit as rapidly as the computer world, so these details will be current for only a year or two. The rest of the book offers an overview of scientific projects that serious amateurs are carrying out these days. Throughout, basic formulas and technical terms are provided as needed, without formal derivations. An appendix with useful references and Web sites is also included. Readers will need more than this book if they are considering a plunge into high-tech amateur astronomy, but it certainly will whet their appetites. Mobberley's most valuable advice will save the book's owner many times its cover price: buy a quality telescope from a reputable dealer and install it in a simple shelter so it can be used with aslittle set-up time as possible. A poor purchase choice and the hassle of setting up are why most fancy telescopes gather dust in their owners' dens. Summing Up: Highly recommended. General readers; lower- and upper-division undergraduates."( T. D. Oswalt, CHOICE, March 2005)
