I'm 45 and my Leupold LPVO at 24mm objective gives a big FOV and good low light capability. How is this explained with the exit pupil equation?
That's easy; FOV is a function of focal length, distance and CoC when the aperture is constant. In an LPVO, the focal length will be quite short and at low magnification, the CoC will be larger so you will have a very large FOV with little magnification. I haven't a clue what the specs of your Leupold LPVO are, but it probably has a low top magnification so the exit pupil will always be a good size. If your LPVO goes to 8X or 10X, you will see a drop off in exit pupil size, but you would probably not be using high magnification at night.
