    Wouldn't he be able to see slightly better with the naked eye? I would think that since binoculars do not transmit the image perfectly he would see a brighter and more detailed image with the naked eye (though I'm sure at this level of glass the difference is slight).

Also, a larger objective will produce a better image with better control of aberrations. I...
