Guest JohnGalway Posted August 23, 2008 Report Share Posted August 23, 2008 Little Butch said: Divide the Magnification by the Objective lens size and you get the Exit PupilFor low light levels they recommended an Exit pupil of 5 or over but we were talking about Binoculars... Butch I think for scopes the magic number is 7. This is why you see fixed mag scopes being multiples of seven or very close such as 6x42, 7x50 and 8x56. 42/6=7, 50/7=7.14, 56/8=7. Quote Link to post
