Someone earlier in this thread mentioned a secondary mirror template for center-dotting purposes. Remember that if you have a fast system, the diagonal will not be centered. It must be off-centered slightly in order to provide an evenly illuminated focal plane. Hopefully the template will take this into account, I'm not familiar with the book mentioned.
