Does anybody have a good collection of Rainbow magazine?
There was a mediocre article in it (all the really GOOD stuff about
flat field lenses, etc. got edited out)
Hi
To get a flat field, use a telephoto lens. The farther
away you can get from the unit the better the depth of
focus. It does require a tripod for a good image.
