Any area of a scopes E/P over the dia. of your individual eyes pupil is superfluous.
The only way to increase or maximise the amount of useful light through the scope to your retina from that point,
is by ensuring the optical device of choice has the best possible 'light transmission efficiency'
I hear that all the time and don't buy it. I believe what my own eyes tell me. The more light my scopes bring in the better I can see.
Your eyes are not telling you anything ,its your brain that actually tells you what you see.
The eye provides nerve signals from the retina to the optic nerve, which sends it to the brains visual cortex,
which provides you with a visual interpretation.
