Sorry, I didn't reference the LULA article on T/S.
That was John MacLean.
When I acquired my 24TSE three years ago, I posted an image on Naturescapes (I had been trying to use tables). I received a reply from Royce Howland (one of the Naturescapes editors), and adopted the method.
No tables, no tape measures, just LV and focusing. It's so dumb-a$$ simple it still amazes me.
