'Tis interesting to me that scope sights don't have an image resolution quality standard like camera lenses do. They focus target image in the reticle focal plane much like SLR cameras do in their 2 focal planes. Such a standard might want to use the second/rear focal plane because that's where the eyepiece lens focuses on. Like camera lenses, scope resolution at different powers will vary.
Cameras use lines per millimeter in their image plane as a standard. Their test subject is placed a fixed distance from the camera for each focal length. Scopes could use similar test targets at 100 yards. I'm working on how to use one with scopes.
Suggestions welcomed.
