Which still makes it about 1/300 degree (or 12 arcseconds) across. That's resolvable with a ground-based telescope, but only an extremely good one (atop Mauna Kea, the best observing site on the surface of the planet, the atmosphere imposes a limit of at best about 0.4 arcseconds). By eye? Not a chance.
