A Ronchi screen is just a piece of glass with many lines to aid in focusing, right? This link has some explanation, but I'm not entirely sure how it works... Link - http://www.astropix.com/HTML/I_ASTRO...0816/I0816.HTM Is it like wearing spectacles with the glass replaced with a fine plastic mesh? That sort of corrects the focus. ![]()

As proper focus is approached the lines become farther apart and eventually "disappear" once perfect focus is achieved. To contrast this, the soft image at the top of this thread was focused by "eyeball" and guessing. |
