Hi, I am having a bit of a problem in fully understanding some measurements I'm getting from Newt.
The angular field of view for the 100% and 75% illuminated area, and the diameter of those fields.
I get the numbers but do not know what would be considered good or bad and some designs throw up e numbers (that I cannot relate to)
Also what does it mean when the 100% zone rays is identical to the on centre zone rays?
Charles
