I've never tried to see what the brain does the blind spot when at the eyepiece, which
must come into play with averted vision and the monocular view. Apparently, the brain
either fills in the blind spot by extrapolating from information surrounding it, or it
simply ignores it. You'd have to get the object to fall on the blind spot to see what
happens. 

You're right to guess that no extrapolation "error" could occur with a binocular or
binoviewer. But something this far off the fovea may not affect averted vision, either. I
don't know. May be an interesting experiment!
