[QUOTE="diriel, post: 546283, member: 26983"] Objective Diameter Divided by power magnification of scope = Exit Pupil. An exit pupil of about 3.5 up to about 5.5 or so will tend to give you good results in low light situations. Of course the quality of the glass and coatings makes a huge difference too. Thing is, as a persons eyes get older you can't take advantage of as much exit pupil. A young set of eyes can take advantage of maybe an exit pupil of 6, while a guy in his mid fourties might be lucky to be able to take advantage of 4.5 to 5 or so. Gary [/QUOTE]
