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.
