Installation
Installation is straightforward and requires no special tools: unscrew the original eyecups counterclockwise and screw the new 44mm eyecups clockwise until they lock in place.
Note: Due to the diopter compensation mechanism on the right eyepiece, after installing both eyecups, the eyecup height may not be perfectly aligned. This is a completely normal phenomenon.
