[QUOTE="cajun, post: 2730928, member: 9772"] One thing I have learned regardless of scope quality. The human pupil can only expand to roughly 5mm in low light. So with a 50mm objective anything over 10 power at last light is pretty much useless. With a 40 mm it’s 8 power etc. 56 will get you 11-12. Not a whole lot of difference. Glass quality is such a subjective thing I dont know how you measure it. Is there an actual standard for light transmission tests or is that just manufacturer data? [/QUOTE]
