Eye relief is the distance from the outer surface of the eyepiece lens to the position where the exit pupil is formed (eyepoint). Looking through binoculars from the eyepoint, you can obtain the whole field of view without vignetting.

What is the advantage of a Picatinny rail?

A major advantage to a picatinny rail is the amount of surface area the shooter has to mount the rings. With a two piece set, if you cannot get the correct eye relief, you need to use an extension base. With a picatinny rail, you can simply move to a different slot.

Parallax is the tendency for a reticle to appear to move in relation to a target when the eye is moved behind the optic. If the position of the shooter’s head changes behind a magnified riflescope, the point of impact can shift.
