Our final images have a 3$\\sigma$ surface brightness detection limit of $\\mu_V\\approx 28.5$ mag arcsec$^{-2}$. The faintest central surface brightness that we measure is $\\mu_{0,V} = 26.1$ mag arcsec$^{-2}$. If these candidates are at the distance of NGC 2784, then they have absolute magnitudes greater than $M_V = -9.5$ mag and effective radii larger than 170 pc.
