Resolution is all about light gathering. That's what the image is when you're looking through a scope. It's light. Resolution of the image you see through your scope is only as good as the optimum exit pupil rating your scope is capable of producing in relation to what our eyes are capable of receiving. Light transmission through the lens is what makes resolution clearer. The better the light transmission, the better the image during low light conditions. That's the way it's been explained to me. Low power scopes do not need big obj. lenses if the glass and coatings are first rate.
