Ceres varies between mag 9.3 and mag 6.7 which are below the nominal naked eye limiting magnitude of ~5. The gain in limiting magnitude for something like 10x50 binoculars (~4.5 magnitudes) would bring Ceres even at its faintest above the limiting magnitude of about 9.5.

$\begingroup$ Can't up-vote yet, but thanks, I can have a go with the binoculars without having to upgrade to anything serious. $\endgroup$– NeomadaFeb 20, 2015 at 23:00
