There have been some great discussions and ideas in this forum about baffling and lining refractor tubes. But it seems like there is no one agreed upon method.
I understand we want block spurious light from the optical path. So we want the inside of the tube to be non reflective. But exactly how many baffles do we need and is their placement carved in stone? Or is there flexibility around placement and number so that we block stray light without inducing vignetting?
thank you, Bill
