Bill, does the book expand on figures 213 and 215 from this page of telescope-optics.net?

215 yes (more designs addressed plus tables that relate ER from a formula basis, 213 no. I did not really address spots as to get an accurate spot you really need the exact prescription of the lens, and of course telescope focal ratio is vital as well.

Me? I'm not buying it!!! It seems that every time I read one of Bill's reviews, it winds up costing me a bunch of money. Can you imagine the financial grief if I had an entire book?
