I use
VizierR to look up stellar magnitudes across several catalogues. If you input 09 38 00.15 -30 08 32.1 (that's your northern star in PA 12°) into "Search by Position" and set the "Target dimension" to 0.04 arcminutes, you'll get several results, including Gaia DR1 and USNO -B1.0. In this case, though, there are no V magnitudes -- only Rmag and Gmag. It's possible a Vmag can be estimated from these, though from different sources I'm not sure that would be very accurate.
For the southern star input 09 37 59.944 -30 09 14.42 with a Target dimension of 0.06 arc minutes. USNO -B1.0 has a Bmag of 18.8, but again there are no Vmags listed. These are dim stars!
