An exit pupil larger than 7mm isn't going to do you much good, unless you're a cat.
True. The point is that the 11.2mm of exit pupil delivered by the scope exceeds the 5.4mm my binoculars deliver yet I still couldn't resolve the animal. This eliminates exit pupil as the culprit and leaves only glass quality, magnification, and maybe eye relief as variables. Both optics were used at the same time, at the same distance (110yds), on the same target. One worked, the other didn't. BTW my binoculars are Pentax 8x42 DCF ED's for a point of comparison to the FX-II I mentioned.
