Thanks. I miss being on a repair ship with a best friend being the chief in charge of the optical shop. I remember the big collimation tubes and could et work done like that for free. I have a set of older Bushnell that I use for checking out our sheep. Whenever I use them we have twice as many sheep as when I walk down and count. I am thinking I will try to use the step by step on the link. Can't hurt.
